Flame Strike or Acid Strike or Cold Strike - doesn't do more damage, just changes the type of damage inflicted. I know certain types of Monks can run along walls, and over the surface of liquid, but they can't stop there, and they can't hang off the ceiling.Ī martial art weapon ( like a quarterstaff ) with a limited number of daily charges, which can convert one type of damage into another? That could be useful for a Monk what has identified an opponent being vulnerable to a particular type of damage. You could give her Slippers of Spider Climbing - imagine a monk who can run up walls and across ceilings, and fight upside down in the room. Monks are tricky to create/leave items for, as they really just are a magic item - Ki-empower strikes, teleportation, super-speed, etc.
