Gauntlet guardians aren't exactly subtle. They simply move adjacent to their foes and start pummeling with their immense fists.
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).
