MoP Classic P5 Immerseus Guide

Boss phase: push health; split phase: cleanse oozes; each cleanse shortens the next boss phase.

Phase Goals

Grouping：Spread out, avoid Vortex and Sha pools, push boss health to split.
Split：DPS kill Sha oozes, healers top off corrupted oozes; prioritize your own sector.
Return：After oozes reach the center, the boss reforms; spread again and repeat until fully purified.

Tank：Boss faces away from group; tank swap on Corrosive Blast stacks.
Tank：During split, each side defends; help kill or control Sha oozes leaking toward the center.
Healer：Polluted oozes must be healed to full; when full, standing near them grants a mana regeneration buff.
Healer：During the grouping phase, reserve mobile healing for Vortex.
DPS：During split, kill Sha oozes closer to the center first; leave distant ones to high-mobility classes.
DPS：The first grouping is the most complete; use Bloodlust if raid tactics allow.

Healing oozes leave more dangerous Sha pools; control their path by zone.
Later the room becomes more chaotic; personal mitigation should be saved for periods when whirlwinds and repositioning coincide.
Corrosive Blast tank swap stacks, Vortex/Sha pool damage taken.
Number of split kills and healing oozes, and how many leak into the center each round.

0:00 Entity 1：Tank takes frontal alone; ranged spread to drop black puddles.
0:19 Split 1：Handle by sector, control/kill black slime, pre-heal blue slime.
0:51 Entity 2：Tank swap in position; the raid moves across water in the rotation direction, not against it.
1:34 Split 2：Don't hold healing cooldowns until oozes reach the center; report zone gaps immediately.
2:27 Split 3：Save burst for dense black slime sectors; use movement abilities to reach the next group.
3:20 Split 4：Prioritize cleansing corruption; don't skip blue oozes for personal DPS.
