Ki Shield (3.5e Invocation)

For 3 ki points per class level, a Saiyan Warrior can use his ki energy to create a 5 foot wide clear field of energy around himself for 1 round as a swift action which grants him a cylindrical shield on all sides that absorbs 10 hit points per class level worth of magical or physical damage and lasts for 1 round. This shield cannot be used after a standard action or a double move action, nor can magical or energy attacks be made from within it. For 9 points per class level this ability can be used as an immediate action even when its not the Saiyan Warriors turn.
