Enough damage

Once enough damage has been done to you, it is hopeful to your opponent rather than yourself. Then the fight between you and your opponent will be over. In the event you are successful. You are able to remain in combat mode for a few moments. But in order to exit combat mode manually, you are allowed to use the key.
In the event your enemy is defeated, it is a non-player character-it often is shortened to NPC. NPC(aion online) is a character that is under control of the gamemaster in role-playing games. In the case, you will earn experience points depending on your level, the level of NPC.
