Armlet of the Damned

This golden band of twisted thorns glistens with an oily shadow that covers it. It digs painfully into the arm of the wearer. The armlet has 5 charges which can be recharged by touching a corpse once per day to regain 1 charge. While wearing this armband you can spend one of the charges as a reaction or when you make an attack. You can use the charges to deal an additional 1d4 damage, gain 1d4 temporary hitpoints, increase the next ability check, saving throw or attack by 1d4.
