Your allies are not powerful enough to stand side-by-side with you at this point, but they can dart into combat to help out. Calling upon an ally does not take an action, and you may do it even when unconscious or otherwise unable to act, but you can only do it during your turn unless otherwise specified.
You can only call on one ally per encounter, and you can only call on any individual ally once per day. Most allies have an immediate effect and then must leave the field, although some grant bonuses that last until the end of an encounter. You cannot call another player’s ally.
