Qi Banish (3.5e Maneuver)

You pull back your fist blazing with spiritual flames, and with a single solid blow you knock them right into the void of the astral sea!

Outsider, humanoid, it no longer matters, as you find ways to strike with such force that the spirit is blown straight across dimensions and drags the body along with it. When you initiate this maneuver, you make a melee attack and deal normal damage, and the opponent must make a Will save DC 19 + your Wisdom modifier, or be sent hurling into the deepest corners of the astral plane! Even on a successful save, their spirit is knocked clean from their body temporarily, stunning the target for 1d4 rounds. Regardless of save, the target is immune to this maneuver for the rest of the encounter.

This maneuver is a supernatural ability.
