Very Silly DnD Character Idea

A healer who is literally "allergic to death". Like when they're near the dead or dying, they sneeze uncontrollably, same as you would expect for someone allergic to pollen to do when around flowers. The kicker? Each time they sneeze near the dead, the dead have been revived. The healer, obviously, is utterly traumatized by this, and has no idea how this is happening, or why it works. They've sneezed other times, and it never healed someone before! Just the dead! (Turns out their patron god just found this really, really fucking funny and keeps reviving the dead at random to fuck with them)
