Orcish Warhide Armor

This studded leather armor provides the wearer
with an additional +1 to AC (AC 13).
When the wearer takes damage from a melee
attack, they can use their reaction to gain
resistance against the attack, reducing the
damage by half.

Crafted from the hides of various fearsome
creatures, the armorer who created the piece
used the innate magical nature of the beasts to
enhance the defenses of the wearer.
