Urgrim gauged the distance down the mound to the eerie coach, and to the zombies still shuffling about the crypts. Laying down the axe and shield, he swung his crossbow off his shoulders. "Valaya, Ancestor Queen," he muttered, pulling one of the silvered bolts from where they thankfully still lodged in his beard. "Bless our clan and hold and hearth." He nocked the quarrel quick, raised the bow, squinted down at the wretched horses. "And deliver us from urki."

He pulled the trigger, and the bolt vanished into the night.

Quick draw, half action to load, and a standard attack. Modifiers are +10 for the standard attack, and any positive size modifier on the horses, but -20 for long range and -10 for the storm, so testing off 31 if there's no size modifier.

ToHit - (1d100)[99]
Damage - (1d10+5)[11]
