Find Master (Su): No matter the distance, as long as it is on the same plane, a gauntlet guardian can find its master.
Spell Storing (Sp): A gauntlet guardian can store one spell of 2nd level or lower that is cast into it by another creature. It uses this spell when commanded or when a predetermined situation arises. Once this spell is used, it can store another spell (or the same spell).
Gauntlet guardians aren't exactly subtle. They simply move adjacent to their foes and start pummeling with their immense fists.
