After a daylong ceremony involving you and at least six monks, you gain the power to knock down foes with your spells.
Benefit: You may apply the concussive template to your spells. You also gain a +2 bonus on Concentration checks made to ignore vigorous, violent, or extraordinarily violent motion while casting spells (see Concentration in the Magic chapter of the Player's Handbook for details).
