What is damage over time?

Some heroes applydamage over time, also known as DoT. DoT damage is dealt in repeated intervals, called ticks, over the duration of the effect.

The first tick occurs immediately when the DoT is applied. Additional ticks then occur at regular intervals until the effect ends.

A DoT effect continues until its timer expires or the affected enemy dies.


DoT ticks can crit and can be affected by changes to the hero while the effect is active. If the hero’s ATK increases, the remaining DoT ticks will deal more damage. DoT damage is also affected by color advantage. For example, DoTs from red heroes deal more damage to green enemies.

Examples of DoT damage includeBleed,Burn, andPoison.


DoT Stacking Rules

A hero or unit can be affected by multiple DoT effects at the same time.

Bleed always stacks, regardless of source.

Burn andPoison stack when applied by different sources. If the same source applies Burn or Poison again, the existing effect’s duration is refreshed instead of adding a new stack.

Note: Burn damage dealt over time by an area effect is not the same as the Burn effect. The area can keep dealing Burn damage for its duration, and overlapping areas can stack their damage. However, this does not apply the Burn effect unless the ability specifically says so, and it does not trigger effects that require Burn, such as Blackbeard’s Douse.
