Vosaxe

Forged with legendary Vostargi obsidian, this
formidable weapon is a mighty heirloom of the
Vostarg.
At the start of the battle, pick one of the bearer's
melee weapons. Improve that weapon's Rend
characteristic by 1. In addition, if the unmodified
hit roll for an attack made with that weapon is 6,
add 1 to the Damage characteristic of that
weapon for that attack.
