Burning

Burning refers to any fire damage over time effect. Burning damage is a synonym for fire damage over time; all burning damage is fire damage over time, and vice versa.

Mechanics
There are several sources of burning, for example:
 * Ignite
 * Burning ground (,, etc.)

Different sources of burning damage stack cumulatively, but multiple applications from the same source do not. For example, two linked with  will not double the burn damage, however a  linked with  together with a  totem will stack with each other. Stacking rules for buffs, debuffs or other effects are defined in terms of that specific buff, debuff or effect interacting with other applications of the same effect, not with other ones that are similar.

All burning effects will remain present on the target until they have run their course, but for each source, only the one with the highest damage per second will cause damage at any given moment. Humanoids, Monkeys and Snakes will flee while burning.

All fire DoT effects are burning damage, but not all of them are ignite. This is a key point when considering buffs and supports such as, which prohibits any elemental status ailment with the linked skill. However since burning damage itself is not an ailment, this support can be used to increase the damage of burning damage for skills that deal burns without igniting, such as, , and.
