(The ghost) (n.) 1. Any NPC that gets low on hit points and suddenly cannot be hit by spells or melee due to being "out of range," even though the NPC appears to be visible and within range (sometimes right in front of you). This happens when the server tells the critter to run away but the client doesn't get the message for a few seconds, and is usually caused by lag. 2. Any NPC that can be seen walking along in the distance, but which disappears as you get close. This is usually due to lag, and often the monster will reappear nearby if you wait a few seconds. 3. (Usually "The ghost") A tough mob hiding in the basement in Unrest. e.g. "We're gonna go camp the ghost - you want in?"
