Barbed Devil’s Bracelet
As an action, you can draw upon the claw’s magic to cast __produce flame_ . Whenever you use the claw in this way, one of the bracelet’s spines disappears and your hit point maximum is reduced by 1d8\. This reduction lasts until you finish a _long rest_ . If this effect reduces your hit point maximum to 0, you die and your body permanently transforms into a _barbed devil_ . When the bracelet has no more spines it becomes a mundane item.
