Damage Over Time

Damage over time (DoT) is a condition that causes the affected unit to constantly take damage until the effect expires, is dispelled, or the target moves out of range. Damage is dealt at the end of each interval, the first of which begins when the spell lands. Some spells come with an initial damage, which may or may not be equal to the periodic damage.

Notes: Initial Damage: Many DoTs start immediately upon impact. The initial damage in this case is the same as damage per instance. Some DoTs have different initial damages. Interval: Time between instances in seconds. Damage per Instance: Damage of each tick after the initial damage. Damage Duration: Duration from start to the last instance of damage. In many cases this is shorter than effect duration, especially ones that start immediately. Number of Intervals: Generally equals Damage Duration / Interval. Does not include initial damage. Max Total Damage: Generally equals Initial Damage + Damage per Instance × Number of Intervals.
