Armor of exchange

this armor, being effectively a living puppet, can increase you're damage in exchange for you're health. You can do this twice per long rest, and are forced to do so at least once per 2 long rests to keep it alive (if you don't, the armor loses all life and becomes normal armor) you can give up as much health as you would like and convert that to damage on hit. aside from taking that damage, until you're next turn you can only recover half of the damage taken

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.
