Ally

Any friendly creature is considered an ally, i.e. anything that appears as a green dot or triangle on the minimap. This includes everybody listed in the party window, as well as friendly animals or NPCs.

Ally and skill usage
The use of the term "target ally" in skill descriptions means that you may use the skill on any of the aforementioned people unless otherwise stated, which is the case with Blood Ritual.

When a skill such as Heal Other uses the term "target other ally", you are allowed to use the skill on any of the aforementioned people, except for yourself.

Generally, allies cannot be resurrected, except for pets, by the use of a specific skill like Comfort Animal or Revive Animal.

Some examples
Ally could mean yourself, a party member, a pet, a NPC accompanying the party (such as Prince Rurik or the Ghostly Hero), a guild battle NPC (such as Guild Lord or Guild Thief), a friendly monster (such as Joe), friendly undead minions, any spirit ceated by a teammate, or any friendly NPC (such as collectors).

Party window
The Party window (P) shows your current team composition under 'Party Members'. Under 'Allies' are listed those allies who are accompanying you for a mission or quest, and your and other party members' pets. Note that the allies listed in the Party window are NOT the only allies you can affect with skills.
