Abilities & Strategy
Overview
Players begin the encounter fighting against Il'gynoth's erupting eyestalks and tentacles, while the monstrous Eye bars the way to the heart of the tree. Defeating these tentacles spawns animated Nightmare Ichor globules, which players can destroy near the Eye to damage it. Once the Eye is defeated, players can enter the hollow to damage Il'gynoth directly for a time, after which the Eye reforms to seal the entrance to the hollow once more, killing any players who remain inside. This repeats until players defeat Il'gynoth.
