Gnarlroot
Amirdrassil, the Dream's Hope, harbours a guardian like no other - Gnarlroot. Beneath the canopy of trees of green and crimson roses, his presence shatters the tranquil melody of nature. Heroic Gnarlroot may not sing a soothing tune, but he orchestrates a different symphony, one that tests the mettle of champions.
This is a single target fight with frequent add spawns.
