At 6th level, you can become semi-tangible as a standard action. While in this form, you are immune to critical hits and gain a +1 deflection bonus to AC. This bonus increases by 1 at 8th level and every 4 levels thereafter.
You can use this power a number of rounds per day equal to your cleric level. These rounds need not be consecutive.
