Death and Resurrection

Your character may die multiple times while fighting or exploring in a particular area. When you die, allies can resurrect you on the field using a skill or Signet (when in PvP a priest or shrine at your team's base can do the job). In cooperative missions, the death of the entire party means you have failed as a team and must return to the outpost to try again. A "wiped" party on a quest will simply resurrect at the nearest resurrection shrine. In either case, you will return to life with a death penalty (DP), which reduces your maximum Health and Energy. http://www.guildwars.com/gameplay/combat/stayingalive/
