DoT is a debuff that lasts for a period of time.
All DoT effects deal damage every 0.3 seconds, but the damage number only appears once every second.
DoT does not hit the enemy when dealing damage. DoT does not trigger affixes such as "XXX on hit", has no hit/evade determination, does not trigger a Critical Strike, and does not deal double damage.
Bonuses
Bonuses from affixes such as: DoT received "+X% damage", "+X% DoT", corresponding Elemental Damage (e.g. "+X% Fire damage"), etc.
DoT from skill effects also enjoys bonuses from skill tags. For example: "+X% Projectile damage" will apply on DoT directly dealt by Projectiles.
Affliction
The Affliction debuff is inflicted on enemies at the same time as DoT. All DoT effects share the same Affliction effect. When under the effect of Affliction, the enemy gradually accumulates Affliction according to the Affliction inflicted every second by the character up to the maximum amount of 100 Affliction.
Each point of Affliction increases the DoT taken by the enemy by 0.5% (up to 50% at 100 Affliction). This effect is affected by the Affliction debuff.
Reaping
When Reaping, all the active DoT on the target will be settled at once according to the given time.
Reaping directly removes the target's HP, so it will not trigger any damage-dealing events.
Reaping generally has a cooldown time, which is not affected by the Reaping Cooldown Recovery Speed and general Cooldown Recovery Speeds.
The cooldown time of Reaping is affected by affix bonuses such as: "+X% Reaping Duration".
