NIGHTMARE CORRIDOR

Ossivorous Spore

Ran 4 Nov 2025 to 20 Apr 2026.

Skills

Doom Bloom

Summons 3 Skeleton Flowers to assist in battle. Skeleton Flowers are immune to damage and attack the nearest enemy. They disappear after receiving damage 12 times, or after 8 seconds. Passive: Every 2 seconds, Ossivorous Spore recovers a certain percentage of its health for every Skeleton Flower on the battlefield.

Binding Thorn

Ensnares the enemy hero who deals the highest damage, pulling them towards itself and briefly devouring them. This deals damage equal to 250% of its Attack Rating, dispelling the majority of their buffs, and reduces the damage they deal by 70% for 10 seconds. The location where the hero was entangled spawns 1 Skeleton Flower.

Toxic Mist

At the start of battle, it releases poisonous mist over the entire battlefield for 20 seconds. During this period, enemies lose health equal to 80% of its Attack Rating per second. Enemies in the mist suffer Poison, reducing the damage they deal by 95% while affected. This effect can be dispelled, but it will be instantly reapplied. Once an enemy's Poison has been dispelled 5 times, it will no longer be affected by Poison. Additionally, the normal attacks of Skeleton Flowers and the Ossivorous Spore deal 100% more damage, while their Attack Speed is increased by 25 points.
