Gargoyle Stoneplate

Gargoyle Stoneplate is an Arena-exclusive Prismatic Tank item providing +15 Ability Haste, +65 Armor, +65 Magic Resistance, and +10% Movement Speed. Its active UNBREAKABLE grants the carrier a shield for 300 (+ 100% bonus health) that decays over 5 seconds, plus 25% increased champion size for the same 5-second duration. 30-second cooldown. UNBREAKABLE is auto-targeted, has no cast time, and does NOT break stealth. Gargoyle Stoneplate is the Arena Prismatic pure-defense reactive shield item — its stat bundle (65 armor, 65 MR, 10% MS) is the most balanced mixed-resistance package of any Prismatic in the documented pool, and UNBREAKABLE’s bonus-health-scaling shield provides a substantial on-demand HP buffer precisely when the tank is about to absorb the largest burst. Strategy note: UNBREAKABLE is best activated right before taking high amounts of damage — its 5-second decay window is the tank’s primary survival tool during the opponent’s peak burst window.

📊 Stats at a Glance

💡 Gargoyle Stoneplate vs Radiant Virtue — Two Tank Prismatics With Different Roles: Both Gargoyle Stoneplate and Radiant Virtue are Arena-exclusive Prismatic tank items, but they serve fundamentally different functions. Radiant Virtue is a team-support tank item — GUIDING LIGHT passively heals the partner on ultimate cast, with no active defensive ability of its own. Gargoyle Stoneplate is a personal-survival tank item — UNBREAKABLE is an on-demand reactive shield that protects the carrier during burst windows, providing no team healing. The choice between them in an Anvil: Radiant Virtue for tank+carry compositions where the carry needs passive sustain; Gargoyle Stoneplate for solo-carry tanks or compositions where personal survival is the constraint and the team doesn’t need healing support.

💡 The 100% Bonus Health Shield Scaling — Why HP Stacking Is Mandatory: UNBREAKABLE’s shield scales at 100% of the carrier’s bonus health — one-to-one. Every point of bonus HP (item-granted health) adds exactly one point to the shield. At 500 bonus HP: shield = 800. At 1500 bonus HP: shield = 1800. At 3000 bonus HP (extreme HP build): shield = 3300. The 300 flat component is almost irrelevant at high bonus HP — the scaling entirely dominates. A tank who builds Gargoyle Stoneplate with zero HP items activates UNBREAKABLE for only 300 HP total — a meaningless shield in Arena’s damage environment. A tank who builds Heartsteel + Warmog’s + Sunfire Aegis alongside Gargoyle Stoneplate accumulates 2000-3500+ bonus HP, generating a 2300-3800 HP shield from one active — equivalent to absorbing one full health bar of damage instantly.

💡 Decaying Shield — Not the Same as a Static Shield: UNBREAKABLE’s shield decays over 5 seconds — it loses value continuously over the duration, not all at once at the 5-second expiry. If the carrier activates UNBREAKABLE with a 2000 HP shield and takes no damage, the shield depletes to 0 at the 5-second mark through natural decay alone. This is the critical distinction from Sterak’s Gage LIFELINE (which persists until broken by damage): UNBREAKABLE’s shield must absorb incoming damage before it decays away naturally. Activating UNBREAKABLE when no burst is incoming wastes most of the shield value through decay before damage arrives. The strategy note is explicit for this reason: activate immediately before high incoming burst to maximize shield absorption vs decay ratio

UNBREAKABLE Shield Reference Table

The Three Core Properties of UNBREAKABLE

1. No Cast Time — True Instant Activation: UNBREAKABLE activates with zero cast time — no wind-up, no animation, no delay between clicking the active and the shield appearing. This is the same zero-cast-time property as Galeforce CLOUDBURST, and it is the defining survivability advantage in high-stakes moments: when a Zed Death Mark is about to detonate, when a Malphite R is in mid-air toward the carrier, when Syndra’s R orbs are being scattered — UNBREAKABLE can be activated at the last possible moment with no reaction-time gap between the input and the shield. Against telegraphed burst abilities with visible animations, an experienced tank player can activate UNBREAKABLE at the instant the opponent’s burst arrives, maximizing the shield’s value against exactly the damage spike it is designed to absorb.

2. Does NOT Break Stealth — The Stealth Positioning Advantage: UNBREAKABLE is one of the few item actives that does not break the carrier’s stealth when used. Galeforce CLOUDBURST breaks stealth on dash. Night Harvester SOULREND passively triggers from damage events that break stealth when that damage ability does. UNBREAKABLE explicitly does not reveal the carrier when activated. In Arena matchups where a tank has stealth access (Evelynn Arena pairing, Twitch support, items or runes granting stealth), activating UNBREAKABLE while invisible allows the carrier to approach with a full shield already active before the engage reveals position. The opponent faces a shielded tank materializing from stealth — with no window to pre-empt the shield before the engage begins.

3. Auto-Targeted — Zero Execution Complexity: UNBREAKABLE requires no target selection, no directional input, no position setup. One button press shields the carrier immediately. In Arena’s high-stakes 2v2 moments where split-second decisions determine the fight outcome, the zero-execution requirement of UNBREAKABLE means it can be activated under maximum pressure with no mechanical difficulty. Compare to Everfrost GLACIATE (requires directional aiming for root placement) or Galeforce CLOUDBURST (requires location targeting for the dash). UNBREAKABLE’s auto-targeted design is the most reliable item active under pressure in the entire Prismatic pool — it never misses, never misfires, and never requires setup

🎯 Who Benefits Most From Gargoyle Stoneplate in Arena

Champion Archetypes — Arena Specific

• HP-Stacking Tanks Whose Primary Threat Is Burst Damage: UNBREAKABLE’s bonus-HP shield scaling rewards the same HP-investment strategy as Radiant Virtue and Sundered Sky (missing-HP heal). The difference: UNBREAKABLE provides the shield before damage reaches HP, while Radiant Virtue and Sundered Sky recover HP after damage reaches HP. For tanks who face opponents capable of dealing burst damage exceeding the tank’s HP in a single combo window (burst mages, ADC crit builds), UNBREAKABLE’s pre-emptive shield provides protection against the one-shot threshold that HP recovery cannot retroactively address.
• Tanks Who Engage Into Multiple Opponents and Need a Burst Absorption Window: In Arena’s 2v2, the tank’s role often involves absorbing the combined burst of both opponents simultaneously during the engage window. A Malphite R, Amumu R, or Nautilus Depth Charge R lands in the middle of both opponents — the 1-2 seconds after engage landing is the highest incoming damage moment. UNBREAKABLE activated at engage landing absorbs both opponents‘ immediate burst simultaneously, giving the tank 1-2 seconds of shielded combat during which the carry has full time-on-target without the tank being eliminated.
• Tanks in Compositions Where the Partner Cannot Provide Healing or Recovery: In Arena compositions where the partner champion is a pure damage dealer with no sustain mechanics, Gargoyle Stoneplate provides self-sufficient survival that doesn’t depend on team healing. Radiant Virtue heals the partner (requiring the partner to need healing). Goredrinker heals the carrier from missing HP (fighter-specific). UNBREAKABLE shields the carrier independently of the partner’s kit — the tank’s survival is self-contained within one button press.

⏰ When to Take Gargoyle Stoneplate From a Prismatic Anvil

Take Gargoyle Stoneplate When:

• Playing a tank who will face concentrated burst damage in Arena 2v2: UNBREAKABLE is a pre-emptive burst absorption tool. Against Arena opponents who deal concentrated burst (Syndra R, Zed Death Mark, Galeforce CLOUDBURST into burst combo, Lux R into Q into SOULREND), UNBREAKABLE provides a shield that absorbs the burst window before it depletes the tank’s HP. Against sustained-damage compositions (auto-attack DPS, extended trades), the 5-second decay means UNBREAKABLE’s shield still runs down even while absorbing damage — the value is highest against burst rather than sustained damage
• Building a high-bonus-HP build where UNBREAKABLE’s 100% bonus HP scaling generates 2000+ HP shields: The 300 flat shield at zero HP is irrelevant — Gargoyle Stoneplate requires a committed HP investment to be worthwhile. Taking it from an Anvil at a stage where the build already includes or will include 1500-3000+ bonus HP (Heartsteel stacks, Warmog’s, Sunfire Aegis, Thornmail HP components) generates shields in the 1800-3300 HP range — meaningful burst absorption in Arena’s endgame damage environment.
• Needing a tank Prismatic that doesn’t require ultimate-casting to activate: Unlike Radiant Virtue (GUIDING LIGHT triggers on ultimate cast — champion-ability-dependent), UNBREAKABLE is a standalone active with no dependency on ultimate availability. A tank whose ultimate is on a long cooldown or was recently used can still activate UNBREAKABLE on the item’s own 30-second cooldown. For champions with infrequent ultimate access, Gargoyle Stoneplate’s independent active is more reliably accessible than Radiant Virtue’s ultimate-gated passive.

Consider Alternatives When:

• The team composition needs the partner to be sustained rather than the tank personally surviving: Radiant Virtue’s GUIDING LIGHT heals both the tank and the carry partner — the heal is a team resource. UNBREAKABLE only shields the tank. In compositions where the carry partner is the fragile element who needs sustain to survive the fight, Radiant Virtue’s team healing may provide more fight-winning value than Gargoyle Stoneplate’s personal shield.
• The opponent composition uses sustained damage rather than burst: UNBREAKABLE’s decay mechanic means sustained damage compositions (auto-attack DPS, DoT-heavy opponents) partially defeat the shield through natural decay even while dealing damage. Against an ADC who deals 200 DPS continuously, a 2000 HP shield absorbs 2000 HP or decays to 0 in 5 seconds — whichever comes first. Against 200 DPS over 5 seconds: 200 × 5 = 1000 damage absorbed (shield decays faster than damage arrives). Against a 2000 burst in 1 second: full 2000 absorbed before decay. Against sustained damage opponents, the decay reduces UNBREAKABLE’s effective absorption below its face value

💡 Synergies — Arena Specific

Best Item Pairings (Arena Legendaries)

• Heartsteel: Heartsteel’s COLOSSAL CONSUMPTION permanently adds 5-40 HP on champion hit procs — each stack directly scales UNBREAKABLE’s 100% bonus health shield. Heartsteel is the single highest-value pairing for Gargoyle Stoneplate because the HP stacking is continuous and compounding: each Heartsteel proc permanently increases every future UNBREAKABLE activation’s shield size. At 500 Heartsteel stacks (2500 HP added): UNBREAKABLE shield increases by 2500 HP from Heartsteel alone — on top of other HP items. A tank reaching 3000 bonus HP through Heartsteel stacking generates a 3300 HP UNBREAKABLE shield — the highest achievable value in the pool.
• Warmog’s Armor: Warmog’s provides +1000 HP — the largest single-item HP contribution to UNBREAKABLE’s bonus-health scaling. Warmog’s 1000 bonus HP adds 1000 HP directly to UNBREAKABLE’s shield through the 100% scaling. Combined with Radiant Virtue (for team healing) or as a Legendary alongside Gargoyle Stoneplate Prismatic: Warmog’s + Gargoyle Stoneplate creates a 1300 HP minimum shield before any additional HP items or Heartsteel stacks. Warmog’s HEART regen between fights restores HP after UNBREAKABLE has been used, ensuring full HP going into the next fight.
• Sunfire Aegis: Sunfire Aegis IMMOLATE scales with 1% bonus HP — the same bonus HP that scales UNBREAKABLE’s shield. Building toward 2000+ bonus HP simultaneously amplifies both IMMOLATE’s sustained AoE damage and UNBREAKABLE’s shield size. High bonus HP is efficient for both offensive and defensive purposes with Gargoyle Stoneplate + Sunfire Aegis: the tank deals more IMMOLATE damage AND generates larger UNBREAKABLE shields from the same HP investment.
• Sterak’s Gage (Similar Item): Sterak’s Gage provides LIFELINE — a shield at 30% HP threshold. LIFELINE activates automatically when HP drops below 30%, providing a brief shield. UNBREAKABLE is a manual active shield activated before the HP drops. Layering UNBREAKABLE and LIFELINE creates sequential shield windows: UNBREAKABLE absorbs the first burst wave (pre-emptive), HP drops, LIFELINE activates at 30% HP (reactive backup shield). The two shields cover different timing windows — UNBREAKABLE for the expected burst, LIFELINE for the unexpected follow-up.
• Thornmail: Thornmail THORNS reflects physical damage on hit while applying Grievous Wounds. Combined with Gargoyle Stoneplate: UNBREAKABLE absorbs incoming physical damage while THORNS reflects it — the attacker receives THORNS damage for attempting to break through UNBREAKABLE’s shield. Against auto-attack-heavy opponents (ADCs), activating UNBREAKABLE while THORNS is active means the ADC both fails to deplete the tank’s HP (absorbed by shield) and takes THORNS damage for each auto. The combination punishes auto-attack focus on the tank during the UNBREAKABLE window.

Champion Synergies — UNBREAKABLE Timing Combos

• Malphite R into UNBREAKABLE at landing: Malphite Unstoppable Force R is untargetable during the dash — damage cannot reach Malphite during the R animation. UNBREAKABLE activated at R landing (when Malphite becomes targetable) creates an instant shield as Malphite lands in the middle of both opponents. The landing moment is the maximum incoming damage point — both opponents are adjacent and targeting Malphite. UNBREAKABLE absorbs the first 1-2 second burst from both opponents simultaneously while Malphite deals R knockup and follow-up damage. The knockup delay (opponents CC’d for ~1.5s) further reduces incoming damage during the first UNBREAKABLE window, meaning the shield absorbs opponent damage starting after the knockup ends — preserving more shield value through the CC window.
• Cho’Gath Feast R + UNBREAKABLE — Each R cast creates compound value: Cho’Gath’s Feast R permanently increases max HP with each stack. Using Feast during combat triggers UNBREAKABLE (if timing the R activation for the UNBREAKABLE window) — but more critically, each Feast cast increases bonus HP for all subsequent UNBREAKABLE activations. A Feast stack at 500 bonus HP means the next UNBREAKABLE is a 500 HP shield. Five Feast stacks later at 1200 bonus HP: UNBREAKABLE is 1500 HP. Ten Feast stacks at 1800 bonus HP: UNBREAKABLE is 2100 HP. Every fight where Cho’Gath lands Feast stacks on opponents compounds into larger shields in every subsequent fight.
• Zac Cell Division passive revive + UNBREAKABLE: Zac’s Cell Division passive causes Zac to revive when reaching 0 HP (1-second death, 10% HP revival, limited frequency). Activating UNBREAKABLE at the moment of Cell Division revival creates a full shield on a champion who just returned from death at 10% HP. The opponent has typically exhausted their cooldowns killing Zac — UNBREAKABLE at revival gives Zac a fighting chance with a large shield buffer while the opponent waits for cooldowns to return. A 2000 bonus HP UNBREAKABLE at Cell Division revival = 2300 HP shield at 10% HP — meaning Zac effectively has 10% HP + 2300 HP shield simultaneously at revival.

❌ Common Mistakes & How to Avoid Them

• Activating UNBREAKABLE too early — before the burst window: UNBREAKABLE’s shield decays over 5 seconds regardless of incoming damage. Activating it 3 seconds before the opponent’s burst lands means the shield is already 60% decayed when the damage arrives. The official strategy note is direct: UNBREAKABLE is best activated right before taking high amounts of damage. ‚Right before‘ means within 0-1 seconds of the expected burst — not at the start of the fight, not when approaching the opponent, not at full HP. The timing discipline of holding UNBREAKABLE until the last moment before burst defines whether the item provides full value or partial value.
• Building Gargoyle Stoneplate without HP items: UNBREAKABLE at zero bonus HP is a 300 HP shield. At standard fight-start HP loss rates in Arena, 300 HP is absorbed in under 1 second against most damage sources — providing essentially no protection. Without HP items, Gargoyle Stoneplate provides 65 armor, 65 MR, 15 AH, 10% MS as pure stats, with the active being irrelevant. Building Gargoyle Stoneplate without HP items wastes the defining mechanic entirely. Commit to HP-stacking build from the first Legendary purchase or choose a different Prismatic.
• Confusing UNBREAKABLE’s decay with Sterak’s LIFELINE’s static shield: Sterak’s Gage LIFELINE provides a static shield that persists at full value until broken by damage (within its duration). UNBREAKABLE’s shield decays regardless of damage taken — it drains away even if no damage hits the carrier. This is a fundamental behavioral difference: Sterak’s shield can wait until attacked, UNBREAKABLE’s shield cannot. Players who activate UNBREAKABLE and then reposition for several seconds before engaging lose shield value to decay before any damage is absorbed.
• Not using the stealth non-break property for pre-engage shielding: UNBREAKABLE does not break stealth — this is explicitly documented as a unique property. In Arena matchups where the tank has stealth access (Evelynn pair, Twitch support, Camouflage from augments or runes), activating UNBREAKABLE before the engage begins while still invisible creates a shielded engage with no tell to the opponent. The opponent sees a tank materialize from stealth already carrying a 2000+ HP shield — the window for the opponent to react and pre-emptively burst the tank before the shield is active disappears entirely when UNBREAKABLE is used in stealth.
• Not accounting for the size increase in hitbox-sensitive matchups: UNBREAKABLE increases champion size by 25% for 5 seconds. While primarily visual, larger champion size can increase hitbox — making the carrier easier to hit with skillshots during the UNBREAKABLE window. Against opponents with high-velocity skillshots (Lux Q, Syndra spheres, Ashe R), the 25% size increase may marginally increase the hitbox width, making skillshots easier to land during the window. In practice this is a minor consideration — the shield benefit overwhelms any marginal hitbox increase — but worth being aware of when activating UNBREAKABLE against skillshot-heavy opponents.

⚔️ Counterplay Against Gargoyle Stoneplate in Arena

Breaking UNBREAKABLE’s Shield

• Sustained Damage Over Time — Decaying Alongside Shield Decay: As documented in the decay section, sustained damage sources partially defeat UNBREAKABLE through the decay race. If the opponent’s DPS rate is lower than the shield’s decay rate per second, the shield decays away naturally without being fully absorbed through damage. Against a Gargoyle Stoneplate tank, sustained DPS at 300-400 DPS is less efficient against UNBREAKABLE than burst — the shield decays faster than it absorbs at those DPS rates. High-burst opponents who deal 2000+ damage in a 1-2 second window fully stress UNBREAKABLE’s capacity.
• Grievous Wounds on the Partner, Not the Tank: UNBREAKABLE provides no healing — it is a shield, not a heal. Grievous Wounds does not reduce shield absorption capacity. However, pairing Grievous Wounds applied to the carry partner alongside burst to the Gargoyle Stoneplate tank creates a double-threat: the tank’s UNBREAKABLE absorbs burst temporarily, but the partner cannot sustain through the fight period while GW is active. Attack both simultaneously — the tank’s shield expires in 5 seconds, and without healing the partner takes full DPS from the onset.
• Waiting Out UNBREAKABLE’s 5-Second Window: The simplest counter: don’t burst during UNBREAKABLE’s active window. Against a tank who has activated UNBREAKABLE, holding burst abilities for 5 seconds until the shield expires fully wastes the shield through decay rather than letting it absorb burst damage. After UNBREAKABLE decays: 30-second cooldown before the next activation. Opponents who can gap-close, apply CC, and delay their burst by 5 seconds defeat UNBREAKABLE’s shield entirely through patience rather than power.

FAQ

Q: Does UNBREAKABLE’s 100% bonus health scale with temporary bonus HP from item actives?

A: UNBREAKABLE scales with bonus health — item-granted permanent HP additions. Whether temporary bonus HP from actives (other item actives that temporarily increase max HP) contributes to UNBREAKABLE’s scaling depends on whether those temporary HP sources count as bonus health in the game’s stat classification. For conservative build planning, assume only permanent item-granted bonus HP (from stat lines, not temporary effects) reliably scales UNBREAKABLE. Radiant Virtue’s GUIDING LIGHT 12.5% temporary max HP expansion is max health increase, not bonus health — likely not scaling UNBREAKABLE’s 100% bonus health.

Q: Can UNBREAKABLE be activated while in Zhonya’s stasis?

A: Zhonya’s Hourglass stasis makes the champion untargetable and unable to act for 2.5 seconds — during stasis, the champion cannot activate items, cast abilities, or take any action. UNBREAKABLE cannot be activated during Zhonya’s stasis. However, UNBREAKABLE can be activated immediately before entering stasis (no cast time means zero-delay shield application before the stasis begins) or immediately after stasis ends. Using UNBREAKABLE in the frame before Zhonya’s activation layers both protections sequentially: UNBREAKABLE shield absorbs pre-stasis damage, stasis prevents damage during 2.5s, UNBREAKABLE has 5-second decay — approximately 2.5 seconds of shield remaining when stasis ends.

Q: Does the 25% size increase from UNBREAKABLE affect abilities that scale with champion size?

A: Certain champion abilities have effects that scale with the champion’s size (Cho’Gath’s Vorpal Spikes E range increases with Feast stacks that also increase size). Whether UNBREAKABLE’s temporary 25% size increase contributes to size-scaling ability effects depends on the specific champion’s size-scaling implementation. For most champions, the 25% size increase is primarily cosmetic with potential minor hitbox implications. For Cho’Gath specifically, stacking Feast increases permanent size and ability ranges — UNBREAKABLE’s temporary 25% size increase likely provides proportionally smaller benefit than Feast’s permanent stacking but may briefly extend size-dependent effects during the 5-second window. This is an edge case worth in-game verification for size-scaling champions.
