I've got no idea for Stunned, though.

And yeah. Knockback prevention is enough. No need to worry ;D

Stunned sounds like it would be inflicted by heavier things hitting with a lot of force, but not necessarily anything that pierces. IIRC, the Rubber Mallet inflicts it, as well as some other heavy things. Boomerangs like the Paladin's Hammer come to mind.
