Mind-Affecting
A mind-affecting weapon affects only creatures with minds; targets that are immune to mind-affecting effects are immune to this weapon. The damage from mind-affecting weapons is normally untyped, in which case it is affected by the same things that affect damage from the spell mind thrust. For example, if a creature was immune to mind thrust, it would also be immune to untyped damage from a mind-affecting weapon.
