While you are actively engaged with a monster, another player, or are taking damage from a nearby source, you are considered "in combat". Being in combat has several effects:
- Combat rules apply to health and mana regeneration:
- You no longer regenerate health automatically.
- Idle mana regeneration is disabled. This means you regenerate mana more slowly, and have to rely on your intellect and equipment more.
- You cannot eat food in combat (potions still work, however).
- You cannot switch maps inside of dungeons.
- Certain abilities (such as Hunter's Veil of Shadows) do not work in combat.
By default, players are not in-combat and certain actions will put them in-combat for a certain period of time. These actions will also restart the In-Combat Delay if the player is already in-combat.
Currently, the following actions will put a player in-combat for ten seconds:
- Attempting to deal damage to a valid target (even if the attack misses).
- Actually dealing damage to a monster or a player.
- Receiving damage.
- Starting to cast any skill on a valid target.
- Starting to cast any skill on the ground.
- Starting to cast any skill on another player that is currently in-combat.
- Starting to cast any skill on yourself while you are in-combat.
- Healing another player that is currently in-combat.
- Healing a monster (i.e., it runs into the AoE of Healing Springs).
- Boss encounters lock you into combat until the encounter ends (that is, the boss resets or is defeated).
If all the monsters attacking a player are killed (and the player is not on a PVP map), the in-combat timer ends prematurely.
