Damage over time (DoT) is a term used to describe a single spell or attack which deals full damage not instantly but over a period of time, dealing a portion of its total damage at regular intervals. The damage is often done every second or every half-second, and each instant in which it is dealt is called a "tick."
The slow effect fromalways applies a 20% slow from abilities which deal this type of damage; the slow is applied from the first tick of the DoT until 1 seconds after the last tick. The behavior with Area of Effect DoT spells is currently bugged in that a full 40% slow is applied for 1 second.
For single-target DoT spells, spell vamp will be applied to the total amount of damage dealt by all ticks.
Becoming untargetable for example Fizz's Playful/Trickster and Vladimir's Sanguine Pool does not stop the damage from DoTs. However, stasis effects like active, Bard's Tempered Fate and self-casting Lissandra's Frozen Tomb will prevent you from taking DoT damage.
