This armor is constructed of a heavy padded hide jerkin overlaid with metal plates on the shoulders and back, ornamented with teeth and horns of various beasts. While wearing this armor you gain a +1 bonus to AC. While you are using your Rage feature, if your rage would end because you have not attacked or been attacked in a turn, you can spend a Hit Die to sustain your rage for another turn, as if you had met the requirements. You can expend multiple Hit Dice on successive turns to maintain rage, but this cannot extend your rage longer than the normal duration specified by your Rage feature.
This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.
Notes: Bonus: Armor Class, Requires attunement by a barbarian
