Stonehorn Blade

Carved from the horns of a mythical beast, this blade strikes with the force of an avalanche.
Pick one of the bearer's melee weapons to
be a Stonehorn Blade. Roll a dice at the end
of any phase in which any wounds were
inflicted by that weapon. On a 5+ you can
pick an enemy unit within 3" of the bearer.
That unit suffers D3 mortal wounds.
