Damage over time

"Damage Over Time" redirects here. For the passive skill, see Damage Over Time (passive skill).

Damage over time (often referred to as DoT) is a damage inflicted continuously over a period of time. Unlike the other three damage sources, damage over time does not hit.

Mechanics

All damage over time effects are a kind of debuff. A creature can have multiple applications of these debuffs of the same type but usually only the one with the highest damage per second works at any given time (except for poison where all applications stack cumulatively); this is true even in the case of effects applied by different players or sources.

For example, if two players each apply the ignite status ailment to the same target, only the higher damage per second of the two ignites will affect the target, at least until the higher fades and leaves the second ignite to become the new highest. In this context, two damage over time effects are to be considered the same only if they have the same name; a target may be affected by multiple effects that deal burning damage (such as , ignite and burning ground).

On kill effects

In case of an enemy being killed by damage over time while being affected by multiple DoT effects, the kill is attributed to the owner of the effect that was inflicted first.

Damage over time kills from non-character sources like minions and totems will give the kill and any on kill effects to the owner of the totem or minion. This is a limitation of the game and not an intended game mechanic.

Damage scaling

The following modifiers will directly affect the damage over time; note that some of these modifiers apply only to the DoTs whereas some may also apply to the skill that triggered it:

• Damage over Time
• Damage
• [Damage Type] Damage (e.g. Physical Damage or Cold Damage)
• [Effect] Damage (e.g. Poison Damage or Ignite Damage)
• Trap Damage if applied by a trap
• Mine Damage if applied by a mine
• Totem Damage if applied by a totem
• Minion Damage if applied by a minion

Damage conversion does not apply to damage over time. However, inflicting damaging ailments with base damage of a different type is treated similar to conversion. For example, lightning damage that poisons with 's Your Lightning Damage can Poison will scale its dps with the attacker's elemental damage modifiers..

However, modifiers that increase/reduce damage taken will affect it.

Duration

Tampering with the duration of a damage over time effect will affect the total amount of damage dealt by it but not its damage per second. The exception to this is the Ignited Enemies Burn faster modifier (as seen on and ), which will 'speed up' ignites inflicted by the player, increasing their damage per second at the cost of duration, leaving the total amount of damage unchanged.

Conditional modifiers

There are modifiers that can apply their effects only when a certain condition is met. Modifiers that are conditional on properties of the target do not affect damage over time because only hits are able to check someone else's properties.

Some examples:

Math

• Modifiers that say increased damage over time multiplier are not additive with increased damage over time modifiers that do not include the word "multiplier".

Interactions

• "% Chance to deal double damage" will not affect damage over time, because it does not hit.
• Most damage over time snapshots.
• Recovery and loss are independent and happen consecutively.
  • Players count as Full Life if they recovered to full at the start of a frame. A 1000 life player with 1000 over-time recovery and 800 over-time life loss (in one server frame) will count as full life, despite effectively starting each frame with 200 life remaining. If loss per frame exceeds maximum life, the player will die, regardless of recovery.
  • Players using do not count as leaving Low Life as long as their over-time life loss is greater than over-time life recovery from flasks.

DoT DPS limit

There is presently a limit to how much total damage any enemy can take from damage over time, of approximately 35.8 million damage per second. The exact number is 35,791,394, or (2³¹ - 1) / 60, or the damage cap divided by 60 seconds in a minute (as damage over time is internally calculated per minute instead of per second). This limit applies jointly to all sources of damage over time, and after all modifiers to damage taken by the enemy, such as the damage reduction provided by Delirium or inherent to Uber bosses.

Version history

Version	Changes
3.15.0	Damage over Time Multiplier Prefix modifiers on Weapons are now Suffix modifiers, and can no longer roll as Prefixes. This includes Veiled and Crafted modifiers.
3.0.0	Damage over Time has been reworked. Read version 3.0.0 § Damage Over Time Rework for details.
1.0.2	Generic modifiers to damage dealt will now apply to damage over time that your character causes. Damage over time is not spell damage, nor attack damage, so modifiers specific to those types will not apply. Non-specific "increased damage" modifiers will apply to damage over time. Type-specific modifiers will apply as well. For example, "increased fire damage" modifiers will apply to fire damage over time.
Before 0.10.0	Introduced to the game
