Professor Putricide Guide: Strategy, Achievements & Loot (ICC WotLK)

Professor Putricide stands as one of the most challenging encounters in Icecrown Citadel, serving as the final boss of the Plagueworks wing. This Professor Putricide Guide will help you understand every mechanic, optimize your raid composition, and execute the perfect strategy to defeat this notorious fight. Whether you’re progressing through Normal or Heroic difficulty, this Putricide walkthrough covers everything you need to know.

To reach Professor Putricide, you must first conquer his two abominations, Festergut and Rotface. Putricide is the final boss of the Plagueworks wing, and these two prerequisite fights are mandatory. Once Professor Putricide is defeated, the raid gains access to the next wing of the citadel, the Crimson Hall, which houses the Blood Prince Council encounter.


Professor Putricide Overview

We emphasize that this encounter is widely regarded as the second hardest fight in ICC, trailing only The Lich King himself. The three-phase structure, combined with constant add management, environmental hazards, and a brutal Phase 3 DPS race, makes this fight a true test of raid coordination and execution.

Professor Putricide Abilities for Icecrown Citadel in Wotlk

This table summarizes every core ability, add mechanic, and phase-specific power used during the encounter.

Ability / Mechanic Phase Type Critical Effect & How to Counter
Slime Puddle P1, P2 Environment Creates a Growing Ooze Puddle that expands infinitely. Counter: Mutated Abomination must use Eat Ooze to consume them.
Volatile Experiment P1, P2 Green Add Summons Volatile Ooze, which immobilizes a player. If it reaches the target, it explodes for massive damage. Counter: Slow with Regurgitated Ooze; all DPS focus kill; stack to split explosion damage.
Unstable Experiment P1, P2 Red Add Summons Gas Cloud, which chases a player with the Gaseous Bloat debuff. Counter: Target must kite constantly (use Nitro Boosts). Must not catch the target (for “Nausea…” achievement).
Mutated Abomination P1, P2 Tank Role Controls the three primary abilities that manage the fight’s adds and puddles. Counter: Off-Tank must maximize Puddle consumption and use Regurgitated Ooze on adds.
Unbound Plague P1, P2 (Heroic) Raid Debuff Damage increases exponentially per second; transferable. Counter: Modern strategy is to let a single player die and resurrect them to avoid the Plague Sickness debuff.
Ooze Variable Intermission (Heroic) Debuff Allows the player to only damage Ooze-type creatures during the intermission. Counter: DPS must swap targets based on their variable color.
Gas Variable Intermission (Heroic) Debuff Allows the player to only damage Gaseous-type creatures during the intermission. Counter: DPS must swap targets based on their variable color.
Malleable Goo P2 Ranged Attack Bounces a goo projectile at 3 ranged players, dealing damage and applying a Attack/Cast Speed slow. Counter: All players must side-step the projectile’s path to avoid the slow debuff.
Choking Gas Bomb P2 Area Denial Drops bombs that create Choking Gas clouds, applying a Hit Chance reduction debuff. Counter: Tank must immediately drag the boss away from the gas clouds. DPS must avoid them completely.
Mutated Strength P3 Boss Buff Permanently increases the Professor’s damage by and attack speed by . Counter: Main tanks must rotate major defensive cooldowns.
Mutated Plague P3 Tank/Raid Debuff Applied to the tank every sec, inflicting exponentially increasing raid-wide damage per stack. Counter: Precise – or -tank swap rotation; raid healers must coordinate defensive cooldowns (e.g., Divine Guardian).

Phase 1 Strategy: to HP

Managing Slime Puddles

Starting at 10 seconds and repeating every 30 seconds, the Professor throws two Slime Puddles at random players, creating Growing Ooze Puddles that deal nature and shadow damage every 2 seconds ( on heroic).

  • Key Strategy Points:
    • Ranged players must maintain loose spread positioning.
    • Tanks should immediately move the boss away from puddles in melee range.
    • Growing Ooze Puddles expand infinitely if not consumed.
    • The Mutated Abomination is essential for puddle management.

Volatile Ooze Mechanics (Green Ooze)

The Volatile Ooze is the highest DPS priority when active. It spawns after 25 seconds from the green tank.

  • Volatile Ooze Strategy:
    • The ooze casts Volatile Ooze Adhesive on a random player, who becomes immobilized.
    • If the ooze reaches its target, it explodes for damage.
    • Damage can be split among all players within 10 yards. Melee should stack with the immobilized player.
    • All DPS must prioritize the Volatile Ooze immediately.

Gas Cloud Tactics (Red Ooze)

Forty seconds after the Volatile Ooze, an Unstable Experiment spawns the Gas Cloud from the red tank.

  • Gas Cloud Management:
    • Fixates on a random player, applying Gaseous Bloat debuff starting at 10 stacks.
    • Target must kite the Gas Cloud effectively. Pro Tip: Nitro Boosts are essential for reliable kiting.
    • Never let the Gas Cloud catch its target or it casts Expunged Gas on the raid. (This is essential for the “Nausea…” achievement).

Red Ooze on Professor Putricide

Mutated Abomination Control

The second tank immediately drinks the Mutated Transformation potion, gaining three key abilities:

  1. Eat Ooze: Consumes Growing Ooze Puddles while standing on them (primary responsibility).
  2. Regurgitated Ooze: Slows Volatile Oozes or Gas Clouds by for 20 seconds. Prioritize this on Gas Clouds.
  3. Mutated Slash: Deals physical damage and applies an armor reduction debuff.

Heroic-Only Mechanic: Unbound Plague

This plague appears every 60 seconds, dealing damage and increasing by each second.

  • Modern Strategy: Simply let the plagued player die with Soulstone or Rebirth available. This is far more efficient than complex plague-passing rotations, as the resulting Plague Sickness debuff deals overwhelming damage if a player receives the plague again later. Sacrificing a player ensures the raid only deals with one major instance of the plague.

Phase 2 Strategy: to HP

Phase 2 maintains all Phase 1 mechanics while adding two dangerous new abilities.

Malleable Goo Mechanics

Starts 15 seconds into Phase 2 and every 20 seconds after.

  • Three goo projectiles bounce in straight lines at random ranged players.
  • Each hit deals damage and reduces attack and casting speed by for 15 seconds.
  • Critical: All players must move aside to avoid the projectile paths.

Choking Gas Bomb Management

After 25 seconds and every 35 seconds thereafter.

  • Two Choking Gas Bombs drop behind Professor Putricide, releasing -yard gas clouds.
  • Gas deals shadow damage and reduces hit chance by for 15 seconds (cannot be dispelled).
  • Tanks must immediately drag the boss away from bombs. DPS should step in front of the boss every 35 seconds until he’s moved.

Phase 3 Strategy: to HP – The DPS Race

Phase 3 is the ultimate challenge, featuring multiple soft-enrage mechanics.

  • Immediate Actions: Use Heroism/Bloodlust immediately.
  • Mutated Abomination Removal: No more puddle consumption is possible. Puddles will fill the room continuously, creating a soft-enrage.
    • Positioning: Drag Professor Putricide along room walls so Growing Ooze Puddles expand into walls, maximizing the remaining safe area.
  • Mutated Strength Buff: Increases the Professor’s damage and attack speed by . Melee swings hit for damage every seconds, requiring high tank cooldown usage.

Mutated Plague: The Core Phase 3 Mechanic

The defining feature of Phase 3 is Mutated Plague, applied to the current tank every 10 seconds. Deals exponential raid-wide damage every 3 seconds based on stack count.

Stacks Raid Damage (per 3s)
1 stack
2 stacks
3 stacks
4 stacks

Critical Rule: If any player with Mutated Plague dies, Professor Putricide heals over 2 million HP per stack, effectively ending the encounter.

Tank Swap Strategy for Mutated Plague

  • Basic Two-Tank Strategy: Each tank takes stacks before swapping.
  • Advanced DPS Taunting Strategy: Uses capable DPS classes to briefly taunt for single stacks, delaying the spike in raid damage. Warning: The DPS player must immediately drop threat after a single tick and the main tank must taunt back, as a DPS player’s health pool cannot sustain the boss’s Mutated Strength melee hits.
    • Classes Suitable for DPS Taunting: Fury Warriors (Shield Wall + Shield Block), Feral Druids (Barkskin + Survival Instincts), Retribution Paladins (Divine Protection).

Phase 3 Time Limit: You have approximately to minutes to burn through the final HP before Mutated Plague stacks overwhelm the raid.


Optimal Raid Composition and Role-Specific Tips

Role Recommendation Notes
Tanks 2-3 2 are mandatory. 3rd is optional for easier Phase 3 stack management.
Healers 4-5 4 healers are optimal for most groups; 5 for progression. Prioritize DPS over excessive healing.
DPS 17-19 Maximize DPS for the unforgiving Phase 3 race.
  • Tank Tips: Save major defensive cooldowns for Phase 3 Mutated Strength. Drag Professor Putricide along walls in Phase 3 to clip puddles.
  • Melee DPS Tips: Volatile Ooze and Gas Cloud always take priority. Never take the Choking Gas hit reduction debuff.
  • Ranged DPS Tips: Maintain spread positioning. Avoid Slime Puddles and Malleable Goo through awareness.
  • Healer Tips: Phase 3 tank damage is extreme. Coordinate raid defensive cooldowns for high plague stack mitigation.

Professor Putricide Achievements

This Professor Putricide guide covers all achievements available from this encounter:

Nausea, Heartburn, Indigestion… (10/25 Player)

Requirement: Defeat Professor Putricide in Icecrown Citadel without any raid member becoming unconscious from gas clouds.

Strategy: All players must avoid being caught by Gas Clouds throughout the fight. The kiter must maintain distance at all times, and if targeted, melee DPS must successfully kite away. This requires excellent movement, Nitro Boosts, and raid awareness. Can be completed on Normal or Heroic difficulty.

Reward: 10 achievement points, contributes to Glory of the Icecrown Raider meta-achievement

All You Can Eat (10 Player)

Requirement: Defeat Professor Putricide in 10-player mode after eating 3 Ooze Explosions.

Strategy: The Mutated Abomination must consume exactly 3 Volatile Ooze explosions by standing in the blast radius when they detonate. This is challenging because:

  • The abomination driver must position perfectly for each explosion
  • The raid must still kill oozes quickly to prevent raid wipes
  • Must be coordinated across multiple ooze spawns
  • Best attempted on Normal difficulty with strong DPS

Reward: 10 achievement points, required for Glory of the Icecrown Raider (10 player)

All You Can Eat (25 Player)

Requirement: Defeat Professor Putricide in 25-player mode after eating 3 Ooze Explosions.

Strategy: Identical to 10-player version but with 25-player difficulty scaling. The Mutated Abomination must absorb 3 Volatile Ooze explosions while the raid maintains control of the encounter.

Reward: 25 achievement points, required for Glory of the Icecrown Raider (25 player)

Glory of the Icecrown Raider (10/25 Player)

Professor Putricide’s achievements contribute to the meta-achievement “Glory of the Icecrown Raider,” which rewards the Bloodbathed Frostbrood Vanquisher mount (10-player) or Icebound Frostbrood Vanquisher mount (25-player).
