The Lich King 25 Heroic is the final boss of WotLK 3.3.5a and the most prestigious kill on WoW Forever in 2026. The fight is 3 phases, ~136 million total HP, and the reward table includes the Invincible mount (1% drop) plus the Val'anyr hammer (2% drop, the BiS healer weapon in the entire expansion). A successful clear is the pinnacle of any WotLK character's career.
This guide is for WoW Forever players in 2026 who are attempting Lich King 25 Heroic. By the end, you'll know the full 3-phase mechanics, the soul harvest timing, the Defile positioning, and the loot drop rates.
Quick answer up front: Lich King 25 Heroic requires 258+ iLevel average, 2 Resto Druids or 2 Disc Priests for the soul harvest, 20-25 players, and 6-12 hours of wipes. The Invincible mount drops at ~1% per kill, so expect 100-300 kills for a drop. Most guilds clear the fight weekly, so 2-6 months of raiding.
Raid requirements for Lich King 25 Heroic
Minimum gear
- Average iLevel: 258+ (T10 4-piece + Emblem of Triumph + Tier 10 weapons).
- Tanks: 250,000+ effective HP.
- Healers: 2,000+ HPS during Harvest Soul.
- DPS: 3,000+ DPS during the Defile phases.
If your raid is below 258 average, you're not ready. Do ToC 25 Heroic 25 for the weapons first. See our WoW Forever Tier 10 Set Bonus Guide: Every Class and Spec (2026) for the full T10 gear list.
Minimum composition
- 2 Tanks: 1 Main Tank (Blood DK or Prot Paladin), 1 Off Tank.
- 18 DPS: 8 Melee (Arms Warrior, Frost DK, Unholy DK, Feral Druid, Enhancement Shaman, Combat Rogue), 10 Ranged (Frost Mage, Fire Mage, Affliction Warlock, Shadow Priest, Beast Mastery Hunter, Survival Hunter).
- 5 Healers: 2 Resto Druids, 1 Disc Priest, 1 Holy Paladin, 1 Holy Priest / Resto Shaman.
The 2 Resto Druids (or 2 Disc Priests) are not optional. The Harvest Soul phase requires 2 healers who can move and heal independently. See our WoW Forever Healer Tier List: PvP and PvE (2026) for the healer compositions.
Phase 1: Necrotic Plague (100% to 70% HP)
The mechanics
- Soul Reaper (every 12 seconds): Applies a 15-second debuff that deals 15,000 shadow damage to the target. Tank swap immediately.
- Necrotic Plague (every 12 seconds): Applies a 12-second DoT to 5 random players that spreads to nearby players. Must be dispelled or healed through.
- Raging Spirits (every 15 seconds): 4 vengeful spirits spawn that must be tanked and burned.
- Defile (every 20 seconds): Creates a shadow patch under the boss. Move out.
The positioning
- Raid: Stack tightly behind the Main Tank. This minimizes the Necrotic Plague spread (the closer players are, the more the DoT spreads between them — so actually spread out).
- Correct positioning: Spread in a 10-yard circle around the boss. Necrotic Plague jumps to the 5 nearest players; spreading reduces the damage each player takes.
- Defile: The boss casts Defile under himself every 20 seconds. Move out of the patch before it lands.
The rotation
- Main Tank: Tank the boss, swap on Soul Reaper.
- Off Tank: Pick up Raging Spirits as they spawn.
- Melee DPS: Stand at the boss's side, spread 5 yards apart.
- Ranged DPS: Stand at 20-30 yards, spread 5 yards apart.
- Healers: Pre-heal for Necrotic Plague 3 seconds before it ticks. Have 2-3 cooldowns ready per Raging Spirit wave.
The wipe points
The Phase 1 wipe points are:
- Necrotic Plague spreading — if the raid stacks too tight, the DoT spreads to everyone.
- Soul Reaper not dispelled on the tank — if the Main Tank dies to it, it's an instant wipe.
- Defile — if 3+ players are in the Defile patch, they take lethal damage.
Phase 1 is the easiest phase. Most guilds clear it in 30-60 seconds.
Phase 2: Val'kyr Shadowguard (70% to 40% HP)
The mechanics
- Harvest Soul (at 70% HP, every 45 seconds): The Lich King pulls 5 random players to Frostmourne. The pulled players must clear 4-spawn adds within 50 seconds. If they fail, the raid wipes.
- Infest (every 20 seconds): Applies a 6-second DoT that deals 4,000 shadow damage per second. Heal through or dispel.
- Soul Reaper (every 12 seconds): Same as Phase 1.
- Defile (every 20 seconds): Same as Phase 1.
Harvest Soul — the hardest mechanic in the fight
At 70% HP and every 45 seconds after, the Lich King pulls 5 random players to Frostmourne. Those 5 players must:
- Kill 4 spawned enemies within 50 seconds.
- If they fail, the whole raid dies. (Even the players not pulled.)
The correct strategy: Pre-assign 5 players to go frozen the moment Harvest Soul is cast. Do not let the boss pick randomly — the picked players should be your 5 best-damage players who can also survive.
The 5 pulled players should:
- Kill the 4 adds in under 30 seconds.
- Then move to Frostmourne and kill the Lich King's heart (a 30k HP object).
The correct positioning
- Frostmourne group: 5 players on the platform, spread out.
- Main group: 20 players stacked behind the Main Tank.
The wipe points
- Harvest Soul not cleared — the pulled players fail the 50-second timer.
- Infest on the frozen players — the 5 frozen players take Infest damage. One of them must be a healer, or the main group needs to pre-assign a healer to the frozen team.
- Defile — same as Phase 1.
Phase 2 is where most wipes happen. Most guilds wipe 30-60% of attempts here.
Phase 3: Frostmourne Harvest (40% to 0% HP)
The mechanics
- Harvest Soul (at 40% HP, then every 45 seconds): Same as Phase 2, but more frequent.
- Soul Reaper, Infest, Defile: All continue.
- Frostmourne: The Lich King is 3x stronger; the adds are faster.
- The Healing Curse (at 20% HP): The Lich King casts a 30-second curse that must be dispelled or cleansed. Holy Paladins and Restoration Shaman can cleanse.
The strategy
- Speed is the answer: The faster you clear the adds during Harvest Soul, the fewer Harvest Soul casts you see.
- Save raid cooldowns for the 2nd and 3rd Harvest Soul casts.
- Use Bloodlust / Heroism on the Frostmourne team, not the main team.
The wipe points
- Harvest Soul fails in Phase 3 — the adds are faster and harder, so the 5 players must be your 5 best-damage players.
- Healing Curse not dispelled — 1 uncleanse curse can wipe the raid.
- Raid cooldowns all used — if you burn everything on Harvest Soul #1, Harvest Soul #2 will wipe.
Phase 3 is the DPS check. If your raid does less than 3,000 DPS, you'll see 3-4 Harvest Soul casts and likely wipe.

Random drops
| Item | Drop rate | Notes |
|---|---|---|
| Val'anyr (healer mace) | 2% | The BiS healer weapon in the entire expansion. |
| Invincible (310% flying mount) | 1% | The most prestigious mount in WotLK. Account-wide. |
| Sanctified Dark Culling | 10% | Tier 10 helm. |
| Sanctified Obsidian | 10% | Tier 10 shoulders. |
| Sanctified Crimson | 10% | Tier 10 chest. |
| Sanctified Darkmarch | 10% | Tier 10 legs. |
The Invincible mount (the most prestigious drop)
The Invincible mount is the BiS 310% flying mount in WotLK 3.3.5a. It drops from Lich King 25 Heroic at ~1% per kill.
Expected time to drop: With a guild that clears weekly (4 Lich King 25 Heroic kills per month), that's 100 kills = 25 months. Most players who get the mount run it 5-10 times per week, so 100-300 kills = 6-18 months of active raiding.
The realistic approach: Most guilds have 1-2 "Shadowmourne hunters" who run the fight as often as possible. Everyone else gets drops through DKP/EPGP distribution.
The Shadowmourne connection: Killing Lich King 25 Heroic also drops Shadowfrost Shards, which are the currency for the Shadowmourne legendary 2H axe. See our WoW Forever Shadowmourne Questline Guide (2026) for the full questline.
