Galvanized Claw
Trick Weapon (Special), Very Rare (Requires Attunement)
Cost: 40,000 gp
Ripping the flesh of the beasts they slay to fashion ferocious weapons is something hunters have gotten remarkably good at over the course of their hunts. While attuned to this weapon, you have Resistance to Lightning and Thunder damage.
Trick Weapon
As a Bonus Action, you can switch between the Transformed and Untransformed states of this weapon. In its Untransformed state, the claw is a sinewy leather gauntlet, made from the muscle and hide of a galvanized prowler. In its Transformed state, the claw surges with electrical energy, merging with its wearer's forearm and turning into a monstrous claw.
Untransformed
The bestial hide invigorates you, giving you the lightning fast reflexes of the galvanized prowler slaughtered to make this gauntlet; you have Advantage on Initiative rolls. In addition, this gauntlet feeds off of your power. If you have Temporary Hit Points when you hit with a melee attack, you deal an extra 1d6 Lightning damage. The gauntlet has 3 charges and regains all expended charges daily at dawn. When you take Lightning or Thunder damage, you can take a Reaction and expend 1 charge to instead take no damage and gain a number of Temporary Hit Points equal to the damage you would have taken.
Transformed
The gauntlet merges with your form, turning your hand into an aberrant claw that you can't be disarmed of. This claw changes the damage of your Unarmed Strikes to 1d8, the damage type to Slashing, and you can use your Dexterity or Strength modifier for the attack rolls and damage rolls made with it. Further, you gain a +1 bonus to attack rolls and damage rolls made with it. When you take the Attack action with this claw, you can make one attack with it as a Bonus Action. In addition, if you have Temporary Hit Points, when you hit with a melee attack using this claw, you deal an extra 1d8 Lightning damage. The claw is too unwieldy to use for delicate handling, such as activating intricate mechanisms (like the trigger of a firearm) or picking locks with Thieves' Tools.
