Reaper's Spellgun

A rod of blackened bone with a bulb at one end comprises a reaper's spellgun, which feels heavier than it looks. You Activate the spellgun by aiming it at one creature and making your choice of a spell attack roll or a firearm attack roll against the target's AC. This spellgun has a range increment of 30 feet. The spellgun fires a shadowy ray, then dissolves into gray mist.

Critical Success The target takes 4d6 void damage and is drained 2 and doomed 1. If it had fewer than half its maximum Hit Points after taking the void damage, it's drained 3 instead. If the Hit Point loss from being drained drops the creature to 0 Hit Points, it dies.

Success As critical success, but for the drained condition, the target is drained 1, or drained 2 if it had fewer than half its maximum HP.
