HoT
Healing over Time - the total healing occurring on a target over a set period of time.
The game evenly divides this total in set intervals, typically three seconds unless specified.
Dexterity and/or effects increasing casting speed (i.e. reducing your casting delay/time) can slightly reduce this interval's duration. This leads to skills capable of carrying out one more periodic heal, without weakening the average heal produced periodically.
- E.g. if Revitalise healed for a base of 400 health, it would be the same as saying 100 health every 3 seconds for 12 seconds). If the interval was reduced to 2.4 seconds, Revitalise would recover 500 health (100 health every 2.4 seconds for 12 seconds).
HoT is affected by magic for magical spells. The increase in healing is added towards the total heal, then divided into periodic heals.
Damage over Time is similar to Healing over Time except one deals damage and the other heals health.
