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==
Bio III is used to deal damage over time to the target. It should always be applied as soon as possible against a target to maximize its effects. 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 Bio III, while can be used to spread it to other nearby enemies. inflicts Bio III and fills the Aetherflow Gauge while inflicting additional damage, and should take priority over the Bio III spell whenever it is off cooldown.
As an instant cast spell that activates the global cooldown, Bio III can be used to weave abilities that are off the global cooldown in between spell casts, such as the aforementioned Fester and Bane.
In order to maximize Bio III's damage over time, it is generally 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.
