Poison Mushroom Cookie Skill: Poison Cloud

Poison Cloud skill icon

Skill

Poison Cloud

  • 12s cooldown
  • Lv.100 values

Tosses mushrooms that release purple poison clouds around themselves and explode, dealing damage. Explosions deal greater damage to enemies in PvE and bosses. Toxic Pools spread around the mushrooms, applying Poison at given intervals and dealing extra damage to Stunned targets (not applied during the effect cooldown). If an enemy becomes Stunned while in a Toxic Pool, they will remain Stunned for a longer time. Somehow, allies who breathe in the spores have their DMG Resist increased. Toxic Pools disappear when the skill is reused.
