Arm of Agathos

This is a metal arm that was constructed from the magics of Agathos, a powerful fire Gin. It was created while making a metal golem bodyguard, but disloyal advisors secreted the parts away from him. Due to its magic, only a fire genasi of Agathos bloodline can use it.  Once attuned, it can not be removed by force. It can be taken off, but the user still has to feel in it and can control it up to 60 ft, as if it were still attached. If the user dies, it becomes inactive.  If it is moved past 60 ft, it will become inactive. The user always knows where it is.

Notes: Melee Weapon Attack: Fire, Resistance: Fire, Bonus: AC Max Dex Modifier, This arm will literally sear itself to the flesh of a stump. Depending on swich side, it will mold itself to become either a right or left arm. It then can detach, leaving a base attached to the arm.
