Kaenic Rookern

What is Kaenic Rookern? đŸ›Ąïž

Kaenic Rookern is the premier passive magic resistance shield item for tanks and frontline champions facing heavy AP burst or sustained magic damage. Its MAGEBANE passive automatically generates a shield equal to 15% of the holder’s maximum health after 15 seconds without taking magic damage — a shield that scales directly with the tank’s HP investment and renews itself in every fight where a 15-second magic-damage-free window can be established. The item quote captures the concept: “Destiny is shaped through cunning, sweat, and steel. Magic violates this principle no longer.”

What distinguishes Kaenic Rookern from other MR items is the self-renewing, HP-scaling shield. Unlike flat MR items (Force of Nature, Spirit Visage) that reduce magic damage proportionally, MAGEBANE provides a total magic damage absorption buffer that stacks on top of the tank’s existing MR reduction. At 4,000 HP (a modest tank HP pool), 15% = 600 magic damage absorbed before any MR calculation applies to the overflow. At 6,000 HP (late-game full tank), the shield reaches 900 HP of pure magic damage absorption.

At 2,900 Gold, Kaenic Rookern provides the highest MR per gold among tank MR legendaries (+80 MR), plus substantial HP (+400) and +100% base HP regen. Building from Spectre’s Cowl and Negatron Cloak with an 800g combine. Sell price: 2,030 Gold. ID: 2504.

📊 MAGEBANE Shield Value — HP Pool ScalingShield = 15% of maximum health. Scales with ALL sources of maximum HP (base HP, item HP, rune HP, ability HP stacking).2,000 HP total: 15% = 300 magic damage absorbed.2,500 HP total: 15% = 375 magic damage absorbed.3,000 HP total (typical early tank): 15% = 450 magic damage absorbed.4,000 HP total (mid-game 2 HP items): 15% = 600 magic damage absorbed.5,000 HP total (late-game 3 HP items): 15% = 750 magic damage absorbed.6,000 HP total (full HP tank — Warmog’s + Heartsteel stacks): 15% = 900 magic damage absorbed.Key insight: building more HP items directly increases MAGEBANE shield size. A Heartsteel-stacking tank accumulating 8,000+ HP late game reaches 1,200+ magic damage absorption per shield activation — more than most AP burst combos deal in one rotation against an 80 MR target.Additionally: MAGEBANE shield absorbs magic damage BEFORE MR reduces it. The shield is consumed first, then remaining magic damage is reduced by MR. This means the shield provides full face value in absorption before the MR calculation applies — effectively functioning as bonus magic EHP beyond the standard MR reduction.

💡 Spectre’s Cowl vs Negatron Cloak — Which to Buy FirstSpectre’s Cowl (1,250g): +HP + MR + regen — the component that provides early durability AND regen for the laning phase. Buy first when taking mixed physical/magic poke in lane and needing HP to survive early all-ins.Negatron Cloak (850g): +40 MR — the highest MR-per-gold component in the game. Buy first when the enemy AP threat is the priority and HP is less critical (sufficient HP from level-ups + runes, but magic damage is the lethal vector).Negatron Cloak first back is often optimal against AP-heavy lanes where getting the MR advantage early in the laning phase provides the most value per gold. At 850g it provides more MR than most full MR items at 3,000g in terms of raw stat.Spectre’s Cowl path: 1,250g first back → full Kaenic Rookern on second back (~1,650g remaining). Negatron Cloak path: 850g first back → Spectre’s Cowl (~1,250g) → combine (800g). Both paths complete Kaenic Rookern at similar total gold investment (~2,900g).

🔼 MAGEBANE Passive — Complete Mechanics Reference

Shield Generation and 15-Second Timer

MAGEBANE generates a magic damage shield automatically after 15 consecutive seconds without taking any magic damage. The shield is not manually activated — it generates passively during any 15-second window where the holder avoids magic damage entirely. Between fights, in base, or during phases where the enemy AP champion is not in range, the shield generates and persists until the next magic damage hit.

The shield value scales with maximum health at the time the shield is checked — if the holder has 4,000 HP when the shield activates, it absorbs 600 magic damage. If the holder then gains more HP (e.g., from Heartsteel stacks or Warmog’s Armor), subsequent shield activations are larger. The shield is a dynamic value tied to current maximum health, not a fixed number at item purchase.

Refresh Timer — The Critical Mechanic

The refresh timer restart mechanic is the most important MAGEBANE rule to understand: the 15-second cooldown for the shield to regenerate starts the moment the shield absorbs any amount of magic damage — even 1 magic damage. This means a single DoT tick, a low-damage ability, or any magic damage source that hits the shield resets the entire 15-second window from zero.

Critically, any remaining shield value is not lost when the timer resets — the wiki explicitly states that “any remaining shield will be restored to maximum value after the refresh.” This means: if the shield has 200 HP remaining when it absorbs magic damage, the refresh timer starts, and after the next 15-second window, the shield is fully restored to the 15% maximum rather than maintaining the depleted 200 HP value. The shield always recharges to full, regardless of how much was absorbed in the previous cycle.

Shield Absorption Priority — Before MR

MAGEBANE’s shield absorbs magic damage before the holder’s MR reduces it. This is a fundamental EHP advantage: a 500 magic damage ability hitting a champion with 80 MR (which would reduce it to ~278 effective damage) instead first hits the MAGEBANE shield for 500 raw magic damage absorbed — the MR calculation never applies to the shielded portion. Only magic damage that exceeds the shield’s remaining value passes through to the HP bar, where MR reduction then applies.

In practice at 4,000 HP (600 shield): a 600 magic damage burst combo is entirely absorbed by the shield. The holder’s HP bar takes zero damage from that combo. A 900 magic damage combo is reduced to 300 that passes the shield, then MR reduces the 300 further — at 80 MR, approximately 167 effective HP damage reaches the bar. The combined EHP contribution of the shield + MR creates a significantly higher magic damage survivability ceiling than either stat alone.

💡 MAGEBANE — EHP Math vs AP BurstScenario: Tank with 4,000 HP and 80 MR (Kaenic Rookern) vs 600 magic damage burst combo (Orianna R).Without MAGEBANE shield active: 600 magic damage → MR reduces to 600 / (1 + 80/100) = 333 effective damage to HP bar.With MAGEBANE shield active (600 HP shield at 4,000 max HP): 600 absorbed by shield, 0 reaches HP bar. Tank takes zero HP damage.Scenario 2: 800 magic damage Syndra R at full combo.With 600 HP shield: 600 absorbed, 200 passes to HP bar. MR reduces 200: 200 / 1.80 = 111 effective HP damage. Tank survives what would have been 444 effective damage without the shield.Full late-game tank at 6,000 HP + 80 MR vs 900 damage AP ultimate: shield absorbs all 900 (900 HP shield). Zero HP damage. The tank is functionally immune to one full AP burst rotation per 15-second cycle.The compounding of 80 MR (55% magic damage reduction) + 15% max HP shield creates a dual-layer magic defense that is uniquely strong against AP burst champions who fire one large combo per rotation window.

💡 Arena Kaenic Rookern — Minor AdjustmentsHP 400→350: minor 50 HP reduction — at 15% scaling, this reduces the MAGEBANE shield by 7.5 HP (at exactly 350 HP from Kaenic alone). The impact on total shield value is negligible since the shield scales with total max HP, not just Kaenic’s HP contribution.Base HP regen 100%→0%: the regen component is entirely removed in Arena. The item’s out-of-combat sustain shifts to natural HP regen from other sources or combat-based healing from augments.MAGEBANE shield (15% max HP, 15s timer): completely unchanged in Arena. Against the AP-heavy augment builds common in Arena, the 15% max HP shield remains fully effective and renews every 15-second window between combats.Arena evaluation: the core defensive value (80 MR + 15% HP shield) is preserved entirely. The HP and regen reductions are minor trade-offs for a slightly lower gold cost environment. Kaenic Rookern is strong in Arena against AP-heavy duo partners or champions with AP-dominant augment sets.

🎯 When to Build Kaenic Rookern

Kaenic Rookern is most effective against AP burst champions who concentrate their damage into one large rotation per cooldown window — the exact pattern that MAGEBANE’s 15-second regeneration cycle is designed to counter. Between the burst champion’s ability CDs (which are typically 15-90 seconds for major ultimates), the shield regenerates and is ready for the next rotation.

✅ Build Kaenic Rookern When:

  • Enemy has a high-burst AP champion: Orianna (Shockwave R), Syndra (Unleash the Scourge R), Veigar (Primordial Burst R), Lux (Final Spark R), Karthus (Requiem R global) — one large magic damage rotation per 60-120 second ultimate CD is the ideal MAGEBANE scenario; the shield absorbs the burst, then regenerates before the next CD window
  • Playing HP-stacking tank or frontline: Cho’Gath (R HP scaling), Sion (P HP growth), Ornn, Malphite, Volibear — every HP item stacked increases MAGEBANE shield value; the item rewards the HP-stacking strategy by converting HP investment into a scaling magic shield that grows larger as the tank builds bigger
  • Enemy AP damage comes in distinct combat windows: the 15-second timer is manageable in fight patterns where the AP champion is not constantly dealing magic damage every second; against sustained DoT mages (Cassiopeia E every 0.3s, Brand Blaze stacking, Malzahar Voidlings) the timer may rarely reach 15 seconds without resetting
  • Laning against an AP top or mid assassin: in matchups like Grasp Tank vs Sylas, Malphite vs any AP assassin, Cho’Gath vs Akali — MAGEBANE provides a persistent shield that regenerates between ability rotations when the opponent isn’t continuously dealing magic DoT damage

❌ Do NOT Build Kaenic Rookern When:

  • Enemy AP damage is sustained magic DoT: Cassiopeia (Twin Fang every 0.3s poisons), Malzahar (Void Swarm + Malefic Visions persistent DoT), Brand (Blaze stacks + repeated casts) — these champions deal magic damage almost every 0.5-1 second, making the 15-second timer nearly impossible to reach. MAGEBANE perpetually resets without generating. Force of Nature (STEADFAST MR stacking during combat) or Spirit Visage (BOUNDLESS VITALITY healing amplifier) provide more consistent value against sustained AP DPS
  • Primarily physical damage threat: MAGEBANE only absorbs magic damage. Against an AD-heavy enemy team, the 80 MR and shield provide no mitigation for physical damage incoming. Sunfire Aegis, Thornmail, or Randuin’s Omen provide more relevant physical mitigation per gold against physical-dominant compositions
  • Need immediate magic damage mitigation: if the game reaches a crisis point where magic damage is already killing the tank before any 15-second window can establish, Kaenic Rookern provides immediate +80 MR (which reduces magic damage proportionally) but the shield may never regenerate under continuous combat pressure. Force of Nature‘s stacking MR during combat (STEADFAST stacks) provides more progressive magic damage reduction in prolonged combat

đŸ‘„ Best Champions for Kaenic Rookern

✅ Ideal Picks — HP-Stacking Frontline Tanks

  • Cho’Gath — Feast (R) increases maximum health permanently with each kill. Every Feast stack directly grows the MAGEBANE shield value — at 10 Feast stacks adding 1,500 HP, MAGEBANE’s shield increases by 225. Cho’Gath naturally reaches some of the highest HP totals in the game (8,000+ HP with full stacks), making the 15% shield scale to 1,200+ magic damage absorption in late game. Rupture (Q) + Feral Scream (W) CC pattern creates windows of 15+ seconds where the enemy AP champion is not able to reach Cho’Gath with magic damage, regenerating MAGEBANE between rotations.
  • Sion — Glory in Death (P) HP growth on kills/minion kills. Every 100 kills adds approximately 3,000 HP — at maximum farm, Sion’s HP pool multiplies MAGEBANE’s shield enormously. Unstoppable Onslaught (R) dive + Decimating Smash (Q) CC creates windows where the enemy AP champion must respect Sion’s initiation, providing MAGEBANE regeneration time. Soul Furnace (W) shield stacks alongside MAGEBANE for layered magic damage absorption in fights.
  • Ornn — Ornn builds Kaenic Rookern and masterworks it into a higher-tier version via Artifacts of the Forge. Call of the Forge God (R) + Bellows Breath (W) + Searing Charge (E) engage rotation establishes Ornn as frontline tank who benefits from MAGEBANE between R cooldown windows (R CD: 130-90 seconds — well above the 15-second threshold for full shield regeneration between fight initiations).
  • Malphite — Granite Shield (P) periodic shield regenerates when out of combat for 8 seconds. The combination of Granite Shield + MAGEBANE creates two independent layered shields: Granite Shield (HP scaling armor shield) + MAGEBANE (HP scaling magic shield). Together they provide dual physical and magic absorption layers simultaneously. Unstoppable Force (R) into burst mage matchups — MAGEBANE absorbs the counter-burst AP damage from the enemy team during the R engage.
  • Maokai — Nature’s Grasp (R) AoE root + Bramble Smash (Q) + Twisted Advance (W) CC chain. Maokai’s sustained CC patterns create windows where the enemy is not able to deal magic damage — MAGEBANE regenerates during hard CC lockdowns. Sap Magic (P) healing passive provides additional HP sustain alongside MAGEBANE’s 100% base HP regen on SR.
  • Dr. Mundo — Going Where He Pleases (R) massive HP regeneration. Mundo stacks HP items for W Burning Agony + R regeneration scaling. MAGEBANE shield at 6,000+ HP (Mundo late game) = 900+ magic damage absorbed per cycle. The combination of Mundo’s R out-of-combat regen, Kaenic’s HP regen, and MAGEBANE’s 15-second shield cycle creates extraordinary in-and-out-of-fight survivability against AP threats.

Situational Picks

  • Volibear — Sky Splitter (E) AoE magic damage + The Relentless Storm (R) AoE lightning — Volibear deals magic damage but also needs to survive AP threats. Against AP-heavy teams where Volibear is the primary AP-diving frontline, MAGEBANE provides the 80 MR + shield layer before Volibear dives into the AP team.
  • Galio — Bulwark of the Ancients (W) magic shield + Colossal Smash (P) magic damage on auto. Galio’s base kit revolves around magic resistance scaling (Colossal Smash deals bonus magic damage based on MR). Kaenic’s +80 MR directly amplifies Galio’s P damage while MAGEBANE adds additional magic damage absorption on top of his existing MR synergy.

❌ Less Optimal

  • AP mages (wrong stat profile): the +80 MR and HP provide zero offensive value; AP mages building defensively should prefer Zhonya’s Hourglass (armor + STASIS) or Banshee’s Veil (MR + spell shield once per 40 seconds) for their magic defense needs
  • Champions facing sustained AP DoT (Cassiopeia matchup): as covered in the when-not-to-build section — the 15-second timer rarely reaches completion against sustained magic DoT; Force of Nature‘s in-combat STEADFAST MR stacking provides proportionally better magic damage reduction during the sustained combat periods where Kaenic’s timer resets

⚙ Recommended Build Paths

Cho’Gath — Maximum HP Scaling Anti-Mage

  1. Spectre’s Cowl — First back (~1,250g) — HP + MR + regen; early durability in AP matchups; component-level stats provide immediate lane sustain while stacking Feast (R)
  2. Kaenic Rookern — First full item — MAGEBANE shield live; +80 MR + +400 HP + +100% HP regen; shield scales with Feast stacks as HP grows; each R stack increases future shield activations
  3. Warmog’s Armor — Second item — WARMOG’S HEART regen; massive HP scaling; at Cho’Gath + Warmog’s HP pool (~6,000+ HP with Feast stacks), MAGEBANE shield reaches 900+ absorption; Warmog’s regen compensates for HP lost between MAGEBANE reactivations
  4. Heartsteel — Third item — COLOSSAL CONSUMPTION: stacking HP on champion hits; every Heartsteel proc permanently increases HP → directly grows MAGEBANE shield cap; Cho’Gath + Heartsteel + Feast is the highest HP ceiling build in the game
  5. Thornmail — Fourth item — GRIEVOUS WOUNDS on physical hits + SPIKESHELL reflected damage; armor + HP; physical damage mitigation to complement Kaenic’s magic damage layers
  6. Spirit Visage — Fifth item — BOUNDLESS VITALITY: +25% healing/shielding received; amplifies MAGEBANE shield restoration value (MAGEBANE shield restoration is not healing, but Spirit Visage amplifies other healing sources including regeneration)

Malphite — Dual-Shield Tank

  1. Negatron Cloak — First back (850g) — +40 MR immediately; highest MR-per-gold component; against AP-heavy mid/top matchup, early MR is the highest priority stat
  2. Kaenic Rookern — First full item — MAGEBANE shield + +80 MR total; combined with Granite Shield (P), Malphite has two independent HP-scaling shields: Granite (armor-type) and MAGEBANE (magic-type)
  3. Sunfire Aegis — Second item — IMMOLATE AoE magic damage in teamfights; HP + armor; physical damage mitigation to complement Kaenic’s magic layer
  4. Warmog’s Armor — Third item — HP scaling amplifies MAGEBANE shield cap; Warmog’s regen sustains between fights; at Malphite + Kaenic + Warmog’s HP: ~5,000-5,500 HP → MAGEBANE shield 750-825 magic absorbed
  5. Force of Nature — Fourth item — STEADFAST stacking MR during combat; at max STEADFAST stacks, Force of Nature provides more in-combat MR than Kaenic in sustained fights; the two MR items together create an extraordinary magic damage resistance ceiling
💡 Kaenic Rookern + Force of Nature — Dual MR Layer StackKaenic Rookern: +80 MR + MAGEBANE shield (15% max HP magic absorption, renews every 15s without magic damage).Force of Nature: +50 MR base + STEADFAST: +5 MR per magic damage hit (stacks up to 10 times, 12 seconds, total +50 bonus MR at max stacks = 100 total MR from FoN alone).Combined MR at base: 80 (Kaenic) + 50 (FoN base) = 130 MR (73% magic damage reduction).Combined MR at max STEADFAST stacks: 80 + 100 = 180 MR (64% effective magic damage after higher MR formula).On top of 130-180 MR: MAGEBANE shield absorbs the first 15% max HP magic damage before MR even calculates. At 5,000 HP: 750 magic damage absorbed free, then remaining damage hits at 73-82% reduction.Practical result: a full AP burst combo needs to exceed 750 magic damage (shield) PLUS deal enough to kill through 73%+ MR reduction on the overflow. Against most AP assassins, this combination makes the tank functionally unkillable by magic damage alone within one combo window.When to build both: when the enemy has 2+ AP threats (AP mid + AP jungle, or AP mid + AP support) where sustained magic damage exposure justifies doubling the MR investment.

❌ Common Mistakes & How to Avoid Them

  • Building Kaenic Rookern against sustained magic DoT: the 15-second timer requires 15 consecutive seconds without any magic damage. Against Cassiopeia (E every 0.3s), Brand (Blaze stacking + repeated E/W/Q), Malzahar (W Void Swarm + E Malefic Visions persistent), or Teemo (Toxic Shot P on every auto), the timer resets constantly and MAGEBANE never generates. Force of Nature‘s STEADFAST stacks actually build during sustained magic damage combat, making it the superior choice specifically against these sustained AP patterns
  • Not understanding the refresh restores to maximum: after the shield mitigates any magic damage, the refresh timer starts — but critically, the shield doesn’t need to be fully destroyed for the refresh. A shield with 300 HP remaining that absorbs 1 magic damage starts a 15-second refresh, and after 15 seconds, regenerates to full 15% max HP. This means partial shield usage followed by the refresh cycle produces full-value shields consistently — the item doesn’t need to be ‘used fully’ to provide maximum value
  • Forgetting the shield only absorbs magic damage: physical abilities, physical basic attacks, and true damage all bypass MAGEBANE entirely. Against an AD heavy team (3 physical champions), the shield absorbs nothing — the +80 MR provides proportional reduction to any magic damage present, but the shield’s 15% max HP absorption is inactive. Assess the composition’s magic/physical damage split before committing to Kaenic
  • Rushing Kaenic Rookern when behind in lane: Kaenic’s +80 MR and +400 HP are strong, but the shield provides maximum value against specific AP burst patterns. If the game’s primary threat is a fed AD carry, a second armor item provides more relevant mitigation per gold. Match the item choice to the actual damage source killing you — don’t autopilot Kaenic Rookern because the enemy has one AP champion if that AP champion isn’t the primary lethality threat
  • Not stacking HP items alongside Kaenic: the 15% shield scales with maximum HP — every additional HP item improves MAGEBANE’s effective absorption value. Running Kaenic Rookern without subsequent HP items (Warmog’s, Heartsteel) leaves significant shield potential unused. At 2,500 HP the shield is 375; at 6,000 HP it reaches 900. A Kaenic Rookern + Warmog’s combination provides both the shield scaling and the HP pool to maximize it

✅ Best Practices

  • Buy Negatron Cloak at first back (850g) against AP-heavy lanes: +40 MR immediately at the highest MR-per-gold in the component shop; establishes immediate magic resistance before Kaenic Rookern completes
  • Stack HP items after Kaenic for maximum MAGEBANE scaling: every HP item purchased after Kaenic Rookern grows the shield value; Warmog’s Armor and Heartsteel are the highest-impact HP items for maximizing MAGEBANE absorption ceiling
  • Use the 15-second window strategically: in fights where the enemy AP champion has just used their ultimate (Orianna R, Syndra R — 80-120 second CDs), the full rotation window provides MAGEBANE regeneration time. Disengage or position away from magic damage sources after the burst rotation to let the shield regenerate before the next R CD window
  • Pair with Force of Nature against 2+ AP threats: the Kaenic + Force of Nature dual MR stack creates the highest sustained magic damage resistance available in the item shop; build both when the enemy has AP mid + AP jungle or other multi-AP compositions where magic damage represents the primary lethal vector
  • On Cho’Gath: buy Heartsteel for permanent MAGEBANE ceiling growth: every Heartsteel Colossal Consumption proc permanently adds HP, growing the MAGEBANE shield ceiling indefinitely over a long game; the HP stacking trio of Feast + Heartsteel + Warmog’s creates the game’s highest MAGEBANE shield values

FAQ

Q: Does MAGEBANE shield absorb magic damage before or after MR reduces it?

A: A: Before — MAGEBANE shield absorbs magic damage BEFORE the holder’s MR reduction applies. Raw pre-mitigation magic damage is consumed from the shield first. Only the overflow that exceeds the shield’s remaining value reaches the HP bar, where MR then reduces it. This means the shield provides its full stated value in absorption rather than a MR-reduced value.

Q: What exactly restarts the 15-second timer?

A: A: Any magic damage mitigated by the MAGEBANE shield restarts the 15-second timer — including a single point of magic damage. Even a 1-damage magic source resetting the timer to zero. Once the shield is active, any magic damage contact (DoT tick, low-damage auto, low-damage ability) resets the full 15-second regeneration window. Plan for the timer reset whenever any magic damage source is active in the fight.

Q: What happens to remaining shield HP when the timer resets?

A: A: Remaining shield is restored to maximum value after the refresh completes. If the shield has 200 HP remaining when it absorbs magic damage, the 15-second refresh starts. After 15 seconds without further magic damage, the shield regenerates to the full 15% max HP value — not just restoring the consumed portion. The shield always recharges to full regardless of how much was absorbed in the previous cycle.

Q: Does Kaenic Rookern work against AP DoT champions like Cassiopeia?

A: It is significantly weaker against sustained AP DoT patterns. Cassiopeia (Twin Fang every 0.3s), Brand (Blaze + repeated casts), and Malzahar (Voidlings + Malefic Visions) deal magic damage every 0.3-1 seconds, making the 15-second timer restart constantly. MAGEBANE rarely regenerates against these patterns. Force of Nature‘s STEADFAST passive stacks MR during sustained magic damage combat — it actually builds strength under the same sustained magic DoT conditions that prevent MAGEBANE from regenerating. Against dedicated sustained AP DoT champions, Force of Nature is the superior MR item choice.

Q: Does building more HP increase MAGEBANE shield after the item is purchased?

A: A: Yes — the shield value is calculated from CURRENT maximum health at the time of shield activation, not at item purchase. Every HP item built after Kaenic Rookern directly increases future MAGEBANE shield values. A Warmog’s Armor adding 800 HP increases the MAGEBANE shield by 120 HP (15% of 800). Heartsteel stacks permanently adding HP grow the shield ceiling indefinitely over the course of a game. Maximizing HP investment directly maximizes MAGEBANE’s anti-magic-burst value.

Q: Is Kaenic Rookern better than Banshee’s Veil for magic defense?

A: Banshee’s Veil provides: +50 MR, +250 HP, and a spell shield that blocks the NEXT ability (any type: AP or otherwise) — 40-second CD on SR. Kaenic Rookern: +80 MR, +400 HP, +100% HP regen, and MAGEBANE shield (15% max HP pure magic shield, 15-second regeneration cycle). The key differences: Banshee’s spell shield blocks ONE ability regardless of damage type and resets on a 40-second CD; MAGEBANE absorbs ONLY magic damage but scales with HP and resets every 15 seconds without magic damage. Against AP burst champions with one specific kill ability (Veigar R execute, Syndra R), Banshee’s block prevents the ability entirely. Against sustained AP burst (Orianna multiple combos, Karthus repeated rotations), MAGEBANE’s 15-second cycling shield provides more total absorption over a fight. Kaenic also provides significantly more MR (+30 more than Banshee’s) and HP (+150 more).
