⏱ Berserk: 10 minutes of hard enrage, but soft enrage (increasing spam of the Mutated Infection) covers the raid earlier Review
Rotface is the second boss of the Plagued House in the Central Laboratory, another “child” of Professor Putricide and the brother of Tukhlopuz. The battle is single-phase and in mechanics strongly resembles Grobbulus from Naxxramas: the tank keeps the boss in the center of the circle, the raid stands under his feet, and the off-tank kites the slugs along the edge of the room. This is a DPS flight with a soft enrage - the frequency of infections increases over time, and if you don’t kill the boss in time, the raid will simply be overwhelmed by slime.
General tips
- Press Heroism/Bloodlust directly on the bullet: at the beginning, the intervals between infections are long, and you can remove maximum HP while there is no slug chaos on the boss.
- Competently throwing small slugs into the path of the big one is the basis of the entire battle. The raid always keeps the slug tank's position visible.
- The healers spread out and maintain a pre-determined order of dispelling the Mutated Infection (like on Grobbulus).
- The longer it takes to accumulate 5 stacks on a large slug, the less explosions and infections there are - so even, high DPS directly makes the battle easier.
- Before the Unstable Ooze Explosion, the entire pack scatters from the center; This is the best moment for raid defenses.
Abilities
Mutated infection
Debuff
Disease on a random player: ~3900–5125 nature damage per second and reduced healing received by 50% (up to 75% on hard difficulties) for 12 seconds. After removal, a Small Slug appears in the player's place. The further into the battle, the more often it is cast (soft enrage).
Action: The infected person immediately runs back from the raid to the slug tank at a predetermined point; heal dispels ONLY when the player is already in place so that the slug spawns in the desired path.
Slime Splashes
Raid damage
Rotface turns towards a random player and pours green slime into a cone for ~5 seconds, dealing ~5363–5637 Nature damage per second to everyone in the line.
Action: As soon as the boss starts turning around and casting, run behind or to the side of Rotface, do not stand in the cone.
Slug Stream
Raid damage
Slime spills from tanks on the walls, flooding ~1/4 of the room along the edge (never the center). ~4388–6662 damage per second and 25% slow to everyone inside, lasts ~20 seconds. The four zones (NW/NE/SW/SE) are flooded in a cycle—each exactly once per cycle.
Action: Don't stand in puddles. The slug tank must see in advance which zone will be flooded and kite the slugs in clean sectors; if there is a stream on the way, quickly pass and ask for healing.
Sticky goo
Other
Slugs (small and large) splash a puddle of green goo near the target: ~2925–4100 damage per second and slow by 50% to everyone within a ~6 m radius.
Action: Get out of the puddle; The slug tank kites so as not to drive itself and the raid into these spots.
Weak Radiant Ooze
Other
Small Slug Aura: ~3413–3587 nature damage every 2 sec to everyone within a ~10m radius. Causes small slugs to merge with each other - two small ones form a Large Slug.
Action: Bring two small slugs towards each other so that they merge into a large one; Don't stand around unnecessarily.
Radiant Ooze
Other
Large Slug Aura: ~4388–6662 damage every 2 sec to everyone within a ~10 m radius. Attracts and absorbs nearby slugs; For each absorption, the large one receives a stack of Unstable Slime.
Action: Only the slug tank keeps the big one ~10 m away from itself and kites; the raid stays away from his aura.
Unstable Ooze
Other
Stack on Big Ooze: +20% to its damage per use, up to 5 stacks. It accumulates every time the big one engulfs the little one. At 5 stacks the slug casts Explosion.
Action: Count the stacks; control the rate of drainage of small ones so that the explosion occurs predictably.
Unstable Ooze Explosion
Raid damage
At 5 stacks, the Big Slug freezes and explodes, firing 3 (at 10ppl) or 8 (at 25ppl) projectiles at random player locations; each projectile deals ~9750–15375 nature damage to everyone within a ~6 m radius.
Action: As soon as the cast is over, everyone instantly scatters in a spread from the center and from under the projectiles, then quickly returns. A good window for raid defenses.
Destructive Gas
Raid damage HC
Only on hardmode. Like Tukhlopuz: applies infection to a ranged area, ~3900–5125 damage every 2 sec for 6 sec, plus damage to allies at ~8 m and disorientation. At 10HC they hold ~3 ranges, at 25HC ~8, spaced apart from each other.
Action: Ranges and heals will spread ≥8 m so that the gas catches one. The gas should not touch the slug tank.
Positioning
The boss stays strictly in the center of the room, inside the inner circle on the floor - this is the safe zone. The raid is standing close to Rotface's feet/hitbox. Slime streams only flood the edges, so the center is safe from floods, but not from Slime Splashes and Explosion Projectiles.
🛡 Tank
The main tank keeps Rotface in the center, turning him around with Raid Slime Spray. As the slug tank circles the room, the main tank spins the boss so that the cone of spray goes into an empty sector.
✨ Healer
The heals will spread out (especially on hardmode due to the Destructive Gas), some of them sit closer to the main tank so as not to move too much on Splash. A strict procedure for dealing with infection is mandatory.
⚔DD
The miles stack up under the boss and move together, keeping the room clean. Range/castes - at the feet or in front of the boss (part of the ranges are spread over the walls at the start). The infected run back to the slug tank, drain the slug and return to the boss.
Role Tips
🛡 Tips for the tank
- You need at least 2 tanks: main on the boss, off-tank on the slugs. Pal/DK are better suited under slimes due to ranged attacks for pickup.
- Do NOT tank large slugs at point blank range - the damage is too high, only kite from a distance of ≥10 m.
- Be ready to take down the tauntlost big slug; Speed items (Nitro boosters) greatly help with repositioning.
- If you make two large slugs, bring them together, they merge into one and combine stacks (less explosions).
✨ Tips for healer
- Didn't displayMutated infectionuntil the infected reached the right point to the slug tank.
- Keep the designated dispel order so that the slugs fall exactly in the path of the big one, and not throughout the raid.
- The small slug's aura is easier to treat than the infection debuff itself - remove the debuff as soon as the player begins to run away.
- During the peak of infections towards the end of the battle, keep a reserve of mana and AoE heal cooldowns.
⚔ DD Tips
- The miles cluster and move in unison so as not to spread the mucus around the room.
- Range will spread himself so as not to catch Splashes/Destructive Gas in a pack; on hardmode, keep the required number of ranges at a distance.
- Flat maximum DPS = less explosions and infections; it literally reduces the complexity.
- Mages: do not cast Mirror Images and do not go into the Ice Block with an infection - the slug will start running around the raid.
