Bloodsong

What is Bloodsong? ⚔️

Bloodsong is the aggressive kill-pressure support quest final item — the choice for supports who deal damage, set up kills, and want to amplify their physical attack combos through ability-then-auto weaving. As one of 5 final items in the support quest chain (World Atlas → Runic Compass → Bounty of Worlds → Bloodsong), it’s acquired for free via quest completion and targets a fundamentally different playstyle than the tank-oriented Celestial Opposition or the heal-utility Dream Maker and Solstice Sleigh.

The SPELLBLADE passive converts the support’s ability cast into an empowered auto-attack setup: use any ability, and the next basic attack within 10 seconds deals bonus physical damage equal to 100% of the holder’s base AD as an on-hit proc. The Expose Weakness debuff applied to champion targets is where Bloodsong’s carry-setup utility lies — for 4 seconds after the SPELLBLADE empowered hit lands, the affected champion takes 8% increased damage from ALL sources (melee holder) or 5% (ranged holder). Every attack and ability from every ally on the team deals 8% more damage to that target during the window.

This transforms Bloodsong from a pure damage item into a damage amplification platform for the entire team. A Pyke hook-into-SPELLBLADE sequence marks the hooked target with Expose Weakness before Pyke’s support partner (the ADC) bursts them — the ADC’s entire rotation benefits from the 8% damage amplification on every hit. For supports whose primary role is creating kill windows through hooks, stuns, and CC chains, Bloodsong converts each CC into a team-wide damage multiplier on the CC’d target.

📊 Base Statistics

⚡ SPELLBLADE — Complete Mechanics Reference

Core Loop — Ability → Empowered Auto → Expose Weakness

The SPELLBLADE loop is straightforward in theory: cast any ability → land the next basic attack within 10 seconds → deal 100% base AD bonus on-hit → if the target is a champion, apply Expose Weakness. The practical execution involves two decisions: when to weave the empowered auto into the ability rotation (immediately after the ability, or after a CC window), and how to position the empowered auto to hit a champion rather than a minion.

The 10-second window is generous — most support ability rotations complete within 3–5 seconds, leaving ample time to land the empowered auto. The consecutive ability cast refresh extends the window further: if a second ability is cast before the empowered auto lands (e.g., using a hook ability immediately followed by a stun ability), the 10-second timer resets from the second cast. This means supports with multi-CC ability sequences (Thresh Q hook + W lantern + E flay) can weave the empowered auto at the end of the full CC chain without the window expiring.

SPELLBLADE — Critical Interaction Rules

Expose Weakness — Team-Wide Amplification Window

Expose Weakness is the component that elevates Bloodsong from a personal damage tool to a team-wide damage multiplier. The 4-second window after SPELLBLADE hits a champion covers a full ADC auto-attack sequence, most mage ability rotations, and the primary burst of most assassin combos. Against 2,000 HP targets receiving the full team’s DPS under 8% Expose Weakness, the amplification represents a substantial burst of bonus damage distributed across every attacking team member.

The melee vs. ranged distinction (8% vs 5%) affects how valuable Expose Weakness is depending on the holder’s range classification. Melee supports (Pyke, Pantheon, Thresh in melee range) apply the more powerful 8% amplification — appropriate since melee supports are expected to be in close proximity where the empowered auto naturally hits the intended champion target. Ranged supports (Lux, Karma, Brand) apply 5% but from safer distances where the empowered auto can be landed without diving into melee range.

🎯 When Bloodsong Is the Right Choice

Choose Bloodsong When:

• Playing an aggressive kill-pressure melee support who combos ability use with auto-attacks: Pyke, Pantheon, Camille support, and other melee supports who engage with abilities and follow up with auto-attacks maximise SPELLBLADE value. Every engage becomes: ability (CC or damage) → empowered auto → Expose Weakness → carry finishes the kill. The 8% melee Expose Weakness amplifies every ally’s follow-up damage on the target for 4 seconds, often determining whether a kill completes within the engagement window.
• Your carry benefits from the Expose Weakness amplification on the specific enemy champion: Expose Weakness’s 8% damage increase from ALL sources applies to the carry’s full damage rotation — auto-attacks, abilities, items. Against high-HP targets (tanks, bruisers) where every percentage of damage amplification translates to significant absolute damage, Bloodsong’s Expose Weakness converts the support’s SPELLBLADE application into a meaningful contribution to the carry’s effective damage output against that target.
• The enemy champion lineup has high-priority kill targets (carries, squishy mages): Expose Weakness and SPELLBLADE’s kill-setup identity is most impactful against targets who can actually be killed within the 4-second window. Against a fragile ADC or mid-lane mage, a Pyke hook → SPELLBLADE empowered auto → Expose Weakness → ADC burst often results in a kill within the window. Against tanks with 4,000 HP, the 8% amplification adds less absolute damage — the kill window is harder to close.
• You want to deal meaningful personal damage as a support: SPELLBLADE’s 100% base AD on-hit is a real damage contribution from the support — not just a utility setup for the carry. Supports with high base AD (Pantheon at 100+ base AD at level 18) deal 100+ bonus physical damage per SPELLBLADE empowered auto in addition to their ability damage. For supports who want to be an active damage contributor rather than purely setting up others, Bloodsong’s SPELLBLADE makes each ability-auto sequence a personal kill-pressure contribution.

Consider Alternatives When:

• Playing a frontline tank support who absorbs damage rather than dealing it: Celestial Opposition’s BLESSING OF THE MOUNTAIN (35% damage reduction while taking hits) is the better quest final item for Leona, Nautilus, Alistar who are consistently targeted in teamfights. Bloodsong’s SPELLBLADE requires landing empowered autos on champions — a tank absorbing AOE hits from the entire enemy team has limited ability to consistently execute the ability→auto SPELLBLADE loop during their dive.
• Playing an enchanter who heals, shields, or peels from range: Enchanters (Sona, Janna, Nami, Lulu) primarily support through healing and shielding rather than damage. SPELLBLADE’s 100% base AD bonus is modest on low-base-AD enchanters (some enchanters have 50–55 base AD at level 18), and the playstyle of staying behind the carry conflicts with landing champion-targeted empowered autos to apply Expose Weakness. Dream Maker or Solstice Sleigh are more appropriate final items.
• You want AP damage amplification for a mage support build: Bloodsong’s SPELLBLADE deals physical damage and Expose Weakness amplifies ALL damage (including magic) — but Zaz’Zak’s Realmspike directly amplifies ability hits with VOID EXPLOSION AoE AP damage. For AP mage supports (Brand, Zyra, Vel’Koz) who deal magic damage as their primary contribution, Zaz’Zak’s provides direct ability damage amplification that scales with AP, while Bloodsong’s SPELLBLADE adds physical damage that doesn’t contribute to the AP build’s scaling.

👥 Best Champions for Bloodsong

Optimal — Kill-Pressure and Damage-Setup Supports

• Pyke: Bloodsong is Pyke’s definitive support quest final item — the SPELLBLADE ability→auto loop slots directly into every Pyke combo. Bone Skewer (Q hold) grabs the target → SPELLBLADE empowered auto lands → Expose Weakness applies → Pyke’s Phantom Undertow (E) stun + Death from Below (R) execute window during the 4-second Expose Weakness. Death from Below’s execute kills generate bonus gold for Pyke and a full gold bounty for a randomly selected ally — Bloodsong’s SPELLBLADE setup is a direct catalyst for R execute conditions since Expose Weakness amplifies the carry’s burst that chips the target below the R health threshold.
• Pantheon (support): Pantheon is arguably Bloodsong’s strongest holder by base AD value — Pantheon’s base AD at level 18 approaches 120+ base AD, making SPELLBLADE’s 100% base AD on-hit deal ~120 bonus physical damage per empowered auto. Shield Vault (W) stun → SPELLBLADE granted → empowered auto lands → Expose Weakness during Comet Spear (Q) follow-up. Grand Starfall (R) repositioning globally also benefits from SPELLBLADE since the R cast time grants SPELLBLADE — arriving in a fight via R with an already-active SPELLBLADE empowered auto ready for the first post-R attack.
• Senna (carry support build): Senna’s Absolution (P) soul collection enables an indefinite AD scaling identity — Senna’s AD grows continuously through game length. SPELLBLADE’s 100% base AD bonus scales with Senna’s base AD (separate from bonus AD from souls, which affects Senna’s scaling differently). Bloodsong fits Senna’s dual identity: the WARD charges provide support vision, the g/10 supplements carry-support income, and SPELLBLADE converts every Absolution (W) root + Dawning Shadow (R) light beam into empowered auto setups. Expose Weakness amplifies the ADC partner’s damage on soul-marked targets.
• Camille (support): Hookshot (E) + Wall Dive engage into Hextech Ultimatum (R) isolation — Camille support creates 1v1 kill windows using R isolation that cuts off the target from ally assistance. SPELLBLADE empowered auto in the isolation window applies Expose Weakness before Camille’s Precision Protocol (Q) double-hit physical damage, amplifying the Q’s second hit (bonus % physical damage) by 8%. In the Hextech Ultimatum isolation where only Camille and the trapped target are present, Expose Weakness amplifies Camille’s own damage exclusively — making it a self-amplifying as well as team-amplifying effect.
• Renekton (support — unconventional): Renekton’s Ruthless Predator (W) empowered stun has a very short cast time → SPELLBLADE granted immediately → empowered auto during the stun window → Expose Weakness on the stunned target. Renekton support is a niche pick, but SPELLBLADE’s interaction with Renekton’s rapid W → auto → Q (Cull the Meek with Fury) → auto sequence creates high physical damage output with Expose Weakness setting up the kill.
• Nautilus (with Bloodsong emphasis): Dredge Line (Q) hook → SPELLBLADE → empowered auto → Expose Weakness during Depth Charge (R) chain knockup. While most Nautilus players prefer Celestial Opposition for the damage reduction, Bloodsong Nautilus is viable in compositions where the primary need is kill setup rather than tank durability. The hook + SPELLBLADE combo marks the hooked target for 8% amplification before the R knockup chain — the carry’s burst into the air during R fires on an Expose Weakness-amplified target.
• Thresh: Death Sentence (Q) hook → SPELLBLADE granted at Q cast → Flay (E) second ability refreshes window → empowered auto at end of chain → Expose Weakness → The Box (R) slow wall containment during 4-second window. Thresh’s multi-CC chain creates extended disruption windows ideal for landing SPELLBLADE at the optimal moment (after all CC has landed, when the target is most vulnerable). Dark Passage (W) lantern use also refreshes the SPELLBLADE window without consuming the charge.
• Blitzcrank: Rocket Grab (Q) hook → SPELLBLADE → Power Fist (E) knock-up → empowered auto during Q displacement → Expose Weakness → ADC follow-up burst. Blitzcrank’s Q instantly pulls the target to melee range, creating the ideal landing condition for the SPELLBLADE empowered auto before the target can reposition. Static Field (R) silence can also be woven into the chain. The hook + SPELLBLADE sequence is clean and fast — less telegraphed than multi-step Thresh chains.

Situational

• Lux (support): Ranged — 5% Expose Weakness (not 8%). Light Binding (Q) root → SPELLBLADE → empowered auto from range → Expose Weakness. Situational because the 5% ranged penalty reduces amplification value, and Lux’s kit has a stronger case for Zaz’Zak’s Realmspike AP build. Bloodsong Lux is viable in AD-forward team compositions that don’t need AP amplification from Lux.
• Karma: Inspire (E) shield + Focused Resolve (W) root — Karma’s root creates SPELLBLADE landing windows. Situational between Bloodsong (for kill-pressure team comps) and Dream Maker/Zaz’Zak’s depending on build direction.

Not Recommended

• Pure enchanters (Sona, Janna, Nami, Lulu): Low base AD makes SPELLBLADE’s on-hit bonus modest; playstyle of staying behind the carry prevents reliable champion-targeted empowered auto application; Expose Weakness is occasionally applicable but not the consistent pattern these champions execute.
• AP mage supports (Brand, Zyra, Vel’Koz) building AP: Zaz’Zak’s Realmspike directly amplifies AP ability hits. Bloodsong’s physical SPELLBLADE adds AD on-hit that doesn’t scale with AP — the wrong damage type for the AP mage support identity.

⚠️ Bloodsong Item Limitations

❌ Common Mistakes & How to Avoid Them

• Not weaving the empowered auto immediately after ability use — letting the 10-second window expire: SPELLBLADE grants the empowered auto at the start of the ability’s cast time with a 10-second window. In the chaos of a teamfight, it is easy to cast multiple abilities without ever landing the empowered auto — each ability cast refreshes the timer, but the empowered auto must actually land to apply Expose Weakness and trigger the cooldown. Develop the habit of always auto-attacking after every ability in champion combat: ability → auto → ability → auto. The 10-second window is forgiving, but the Expose Weakness is only applied when the empowered auto actually lands on a champion.
• Wasting the empowered auto on a minion instead of a champion: SPELLBLADE applies the on-hit bonus physical damage to any basic attack target — including minions. Expose Weakness, however, only applies when the target is a champion. Landing the SPELLBLADE empowered auto on a nearby minion deals the bonus damage but does NOT trigger Expose Weakness, and the cooldown starts from that non-champion hit. In champion fights, ensure the empowered auto targets the enemy champion, not incidental minions or jungle camps in the area. Deliberately target the enemy champion before pressing the auto-attack.
• Building a second SPELLBLADE item alongside Bloodsong — the inactive item wastes gold: Bloodsong’s SPELLBLADE item limitation means holding a second SPELLBLADE item (Trinity Force, Lich Bane, Essence Reaver) results in one of them being inactive. In unusual support builds that want fighter items, check whether a SPELLBLADE conflict exists. If it does, sell the weaker SPELLBLADE item to activate the stronger one — an inactive SPELLBLADE passive is a dead item slot.
• Attempting to build Bloodsong on AP mage supports expecting SPELLBLADE to scale with AP: SPELLBLADE deals 100% BASE AD bonus physical damage — base AD only, not bonus AD, and not AP. An AP mage support building Bloodsong deals SPELLBLADE on-hit damage based on their base AD (typically 50–70 at level 18 for mage champions), not their AP. The Expose Weakness 5% (ranged) amplification is useful but not the reason to build Bloodsong over Zaz’Zak’s for a mage. Choose the right quest final item for the damage type the champion primarily deals.
• Forgetting that SPELLBLADE is proc damage and does not trigger spell effects: Builds relying on spell damage interactions (Electrocute from 3 unique hits including spell damage, or other spell-effect dependent runes/items) should not assume SPELLBLADE’s on-hit counts as a spell effect for those interactions. SPELLBLADE is explicitly proc damage, not spell damage — it does not satisfy conditions that require ability or spell hits for triggering.

✅ Best Practices

• Build the ability→auto habit before every champion interaction — it is the entire item’s value: SPELLBLADE requires only one behaviour change from a standard support playstyle: always auto-attack a champion immediately after using an ability. In lane trades, this means ability-into-auto weaving is mandatory, not optional. In teamfights, prioritise landing the empowered auto on the primary kill target (highest priority carry) rather than any nearby champion. The habit of auto-attacking after abilities is the single most impactful mechanical adjustment for Bloodsong adoption.
• Use consecutive ability casts to extend the SPELLBLADE window during CC chains: If a support uses Thresh Q (hook) and then immediately follows with E (Flay) before landing the empowered auto, the Flay cast refreshes the 10-second SPELLBLADE window. This means multi-CC ability chains allow the support to complete the full CC sequence and then land the empowered auto at the optimal moment — after all CC has landed and the target is fully disrupted — rather than rushing the auto between abilities and potentially missing during animation.
• Prioritise landing Expose Weakness on the highest-threat target the carry is focusing: Expose Weakness’s value is proportional to how much damage the team’s carries deal to the marked target within the 4-second window. Against the enemy ADC (who the carry is likely focusing), 8% damage amplification on a target taking 1,500+ damage from the carry + AP carries = 120+ bonus damage effectively granted by the Bloodsong SPELLBLADE application. Against a tank the carry is not prioritising, the same Expose Weakness generates less total bonus damage due to less damage being dealt into the window.
• Combine with Black Cleaver for the dual physical debuff stack on aggressive melee supports: Black Cleaver’s CARVE armor reduction and Bloodsong’s Expose Weakness from SPELLBLADE both apply from physical hits. The SPELLBLADE empowered auto contributes a CARVE stack on landing. For Pantheon support or other melee supports building both items, the combined debuff (−30% armor + 8% increased damage from all sources) is the most powerful physical damage amplification a support can apply. Recommend Black Cleaver as the first purchased item after Bloodsong for aggressive physical supports who want the dual debuff.
• Track the SPELLBLADE cooldown (1.5 seconds post-empowered-auto) for maximum cycle rate: The SPELLBLADE cooldown starts after the empowered attack is consumed — not from ability use. After the empowered auto lands, 1.5 seconds until the next ability use can prime another SPELLBLADE. Monitoring this 1.5-second window during sustained fights lets the support cycle SPELLBLADE → Expose Weakness → ability → SPELLBLADE → Expose Weakness repeatedly, maintaining near-permanent Expose Weakness uptime on the primary target throughout a sustained multi-second engagement.

🎬 Final Summary

Bloodsong is the kill-pressure support’s quest item — built for the supports who set up kills rather than absorb damage, who deal physical damage as a meaningful contribution rather than purely providing utility, and who want their ability use to trigger a team-wide damage amplification on their primary CC target. The SPELLBLADE passive’s 100% base AD on-hit converts every ability cast into a kill setup, and the Expose Weakness 8% amplification window makes every Bloodsong-holder’s ability→auto sequence a gift to the carry: the next 4 seconds of the carry’s damage output against the marked target is multiplied by 8% — a meaningful number when the carry’s full rotation deals 2,000+ damage into the window.

The extensive SPELLBLADE rule set — proc damage (not spell effects), context-dependent spell shield blocking, blocked vs dodged behaviour, SPELLBLADE limit preventing second SPELLBLADE items, lifesteal applicability with Lich Bane/Dusk and Dawn exclusions, structure triggering, jungle plant non-triggering — defines the technical knowledge layer required to play Bloodsong correctly. Most of these rules are edge cases that rarely matter in standard games, but they become critical in specific matchups: against Sivir E spell shield (SPELLBLADE auto is not blocked), against Nocturne W (standard case not blocked), and in builds where a second SPELLBLADE item is accidentally added.

The most effective Bloodsong supports are Pyke, Pantheon, Thresh, Blitzcrank, and Camille support — champions whose CC chains create natural, reliable SPELLBLADE landing windows where the empowered auto can be precisely directed at a helpless champion target for maximum Expose Weakness value. For these champions, Bloodsong transforms the support quest chain from a passive utility progression into an active kill-pressure system that contributes offensive output and team amplification in every fight.

FAQ

Q: Does SPELLBLADE’s bonus damage crit or scale with crit chance?

A: No — SPELLBLADE explicitly is not affected by critical strike modifiers. The 100% base AD on-hit bonus is a flat proc that does not crit. A critical strike auto-attack with SPELLBLADE active deals the crit-amplified base auto damage PLUS the flat 100% base AD SPELLBLADE bonus separately. Only the auto-attack portion crits; the SPELLBLADE proc does not.

Q: Is SPELLBLADE blocked by Sivir’s Spell Shield?

A: Spell shield does NOT block SPELLBLADE if the empowered attack is delivered as a basic attack (the standard case). SPELLBLADE is blocked by spell shield only if the effect is applied by an ability that triggers on-hit effects — an edge case. In standard play (casting an ability → auto-attacking with the empowered attack), Sivir E or Nocturne W spell shields do not block SPELLBLADE’s on-hit bonus or Expose Weakness application.

Q: Can I hold both Bloodsong and Trinity Force for two SPELLBLADE stacks?

A: No — Bloodsong is limited to 1 SPELLBLADE item. Holding Trinity Force alongside Bloodsong results in one SPELLBLADE passive being inactive (typically the one purchased second or the lower-priority item). Only one SPELLBLADE item can be active simultaneously. Sell the inactive SPELLBLADE item if a conflict arises and keep only the one providing more value for the current build.

Q: Does Expose Weakness apply to the SPELLBLADE hit itself?

A: Yes — the note from the wiki states ‚SPELLBLADE’s triggering attack will benefit from Expose Weakness.‘ This means the empowered auto-attack that applies Expose Weakness also receives the benefit of that Expose Weakness on the same hit — the debuff applies simultaneously with the hit that triggers it, so the SPELLBLADE hit itself deals damage with the 8% amplification factored in.

Q: Does SPELLBLADE trigger against towers?

A: Yes — SPELLBLADE triggers against structures including towers, inhibitors, and the nexus. This makes Bloodsong useful during tower dives and structure-taking scenarios: ability → empowered auto against the tower deals bonus physical damage to the structure. Note that Expose Weakness only applies to champion targets — structures do not receive the Expose Weakness debuff from SPELLBLADE hits.

Q: What happens to SPELLBLADE if the empowered auto is blocked?

A: If the SPELLBLADE empowered auto is blocked (by Braum P passive’s damage reduction mechanic, or other block effects), the block negates the damage, consumes the SPELLBLADE effect, and places it on the 1.5-second cooldown — even though no damage was dealt. The effect is spent. Contrast this with dodge: a dodged SPELLBLADE empowered auto does NOT consume the effect and does NOT start the cooldown — the empowered attack window continues after a dodge.
