Selket’s Bracer
Wondrous Item, very rare (requires attunement)
This bronze bracer is crafted in the shape of a scorpion, its legs curled around the wearer’s wrist, tail raised and ready to strike. It has 4 charges, and it regains 1d4 charges daily at dawn. By expending 2 charges, the wearer can poison a weapon as a bonus action (the tail of the scorpion animates and touches the blade to envenom it). The next creature damaged by this weapon must make a successful DC 14 Constitution saving throw or be poisoned until the end of its next turn. Also as a bonus action, the wearer of the bracer can expend 1 charge to gain tremorsense (30 feet) for 10 rounds. The wearer is immune to the poisoned condition.
