An ally is any being that is not hostile or neutral.
Allies can be divided into four groups:
- PvE — all players and all of their pets and minions.
- WvWvW — all players from your homeworld and all of their pets and minions.
- sPvP — all players on your team and all of their pets and minions.
- NPCs — all friendly NPCs and all of their pets and minions.
Effects that target allies prioritizes party members, then party members' pets and minions, then other players, then friendly NPCs.
An area of effect spell that affects allies may only affect a maximum of 5 targets.
 Special Cases
- An effect that emerges from the player may not consider the player be an ally of the effect unless the effect clearly states "allies and yourself".
