Poison Effects
Takes Poison Damage Each Turn

Poison is a type of debuff that occurs during battle. Heroes afflicted with it take damage equal to 6% of their max HP every turn. A Poison icon will be displayed on poisoned heroes, so you can always check their status.
![]() | The maximum damage is capped at 150% of the skill user's Attack Power. |

Poison Can Be Stacked

Poison can be stacked multiple times on the same target. Since stacking the debuff will also increase the damage, you should reduce the number of stacks as much as possible to suppress the Damage Taken.
Poison Explosion Deals Instant Damage
Poison Explosion is an effect that instantly consumes the remaining Poison turns to deal damage. The damage multiplier varies depending on the skill multiplier of the hero who triggered the Explosion.
Debuff TypesNo Heroes Currently Trigger Poison Explosion
Although Poison Explosion is mentioned in descriptions, there are currently no heroes who can cause Poison Explosion for now. For Bleed, which has a similar effect to Poison, Bi Dam has a Bleed Explosion.
Poison Counters
Poison Immunity

The most effective way to counter Poison is to have a hero with Poison Immunity on your team. Since you will not be poisoned while the immunity effect is active, it becomes easier to keep your heroes' HP high.
Lucy

Lucy is the only hero with Poison Immunity. She has a support-focused kit with an all-ally HP Heal, Debuff Removal, and a Defense buff. Her offensive capabilities are low, but her appeal lies in her ability to greatly enhance the team's survivability.
Lucy Rating & SkillsIncrease Effect Resistance

Increasing your Effect Resistance gives you a chance to block debuffs from enemies. While it doesn't guarantee immunity, it's another reliable way to defend against all types of debuffs.
Debuff Removal

When Debuff Removal is activated, it removes a specified number of debuffs from the target hero. It can remove debuffs with a black background icon, but be aware that debuffs with a red background cannot be removed.
Make Enemy Attacks Miss
Attacks that Miss do not inflict status ailments. You can indirectly prevent Poison by using skills that cause enemy attacks to Miss.

Increase HP and Defense
While poisoned, you’ll keep taking poison damage, but since it doesn’t stop you from doing anything, you can endure it. If you can't avoid being poisoned or remove it easily, consider increasing your HP and Defense.
