Phase Breakdown

1. Phase 1: Phase 1 (Human Form)
   TriggerFight start, after activating all three Ritual Altars in the arena
   MechanicStandard curse-and-attack pattern typical of an Act 1 optional boss.
   CounterThis phase is comparatively straightforward, use it to learn his tells before the harder transformation.
2. Phase 2: Phase 2 (Leshen-like Tree Form)
   TriggerAround 33% health in Phase 1
   MechanicHe becomes briefly untargetable, fully restores his health and barriers, and transforms into a tree-like creature. New mechanics layer on top of his existing kit: a chasing Blood Tornado that applies Armour Break on hit, physical Blood Waves from the arena edges that knock you back, roaming purple insect swarms dealing Chaos damage over time, a large slow-exploding orb that Maims on impact, and purple ground Pustules that explode when approached and stack a debuff called Shadow Surge.
   CounterKeep distance from the Blood Tornado rather than continuously moving away from it in a straight line, a dodge roll or two works better than constant kiting. Never let Shadow Surge stacks reach 5 or more, that's an effective one-shot. If you get pulled into the Wildwood Maze sub-mechanic, follow the glowing wisps immediately since they dissipate over time.

Most Common Deaths

• Letting Shadow Surge stacks from the purple Pustules climb to 5+ before clearing them
• Getting caught by the Blood Tornado while trying to out-walk it instead of using proper dodge timing
• Losing track of the wisp trail in the Wildwood Maze and wasting the window before it disappears
