Combat

Combat in Guild Wars affects many things.

"In Combat"
The game tracks whether or not you are "in combat". You enter combat when you attack an enemy, an enemy attacks you, you use a skill on an enemy, or an enemy uses a skill on you. You stop being in combat about fifteen seconds after any of these things happen. There is no visual indicator within the game showing whether or not you are in combat.

In particular, you cannot do the following things while in combat:
 * Identify items.
 * Salvage items.
 * Gain health from natural regeneration.

Natural health regeneration ends when you lose health (such as from using a sacrifice skill), but this does not necessarily put you in combat.
