Damage over time effects deal damage every server tick, or 3 seconds, independent of the effect's duration. This means that the effect may deal damage anywhere between 0 and 3 seconds after it is applied, and in 3 second intervals afterwards.
==Use==
Miasma is used to deal damage over time to the target, in conjunction with or . Unlike Bio and Bio II, Miasma has a cast time which can make it more difficult to apply, though it does deal minor damage on impact as a tradeoff. It should always be applied as soon as possible against a target to maximize its effects, and it is generally used as an opener followed by an immediate Bio. Against weak enemies expected to die in less time than its duration it may be safely skipped.
The ability deals more damage to targets afflicted with Miasma, while will spread it to nearby enemies at a reduced potency. inflicts both Bio II and Miasma, and once learned should take priority over the Miasma spell whenever it is off cooldown.
At level 58 Summoners gain access to . While under the effect of Dreadwyrm Trance, Miasma's cast time is lowered to instant. As an instant cast spell that activates the global cooldown, Miasma can then be used to weave abilities that are off the global cooldown, such as , in between spell casts.
In order to maximize efficiency on Miasma's damage over time, it is recommended to reapply it with under 3 three seconds remaining, as the final tick of damage from the effect can occur anywhere in that window. This may result in the loss of a tick, but waiting for the effect to drop off before reapplying can result in the loss of two or more ticks and greater DPS loss.
