You have harvested the tail from a wyvern and some more of its hide and made some armor out of it. Now you can use that tail as an attack action on you turn, Range 10 feet, +7 to hit, on a hit (2d6+4) piercing damage and the target must make a DC 14 Constitution save or take (7d4) poison on a failed save, half damage on a success.

Made of interlocking metal rings, a chain shirt is worn between layers of clothing or leather. This armor offers modest protection to the wearer's upper body and allows the sound of the rings rubbing against one another to be muffled by outer layers.

Notes: Resistance: Poison
