Sun Domain

You see truth in the pure and burning light of the sun, and can call upon its blessing or wrath to work great deeds. Sun's Blessing: Whenever you channel positive energy to harm undead creatures, add your level in the class that gave you access to this domain to the damage dealt. Undead do not add their channel resistance to their saves when you channel positive energy. Nimbus of Light: At 8th level, you can emit a 30-foot nimbus of light for a number of rounds per day equal to your level in the class that gave you access to this domain. Any hostile creature within this radius must succeed at a Fortitude save to resist the effects of this aura. If the creature fails, it is blinded until it leaves the area of the spell. A creature that has resisted the effect cannot be affected again by this particular aura. In addition, undead within this radius take an amount of damage equal to your level in the class that gave you access to this domain each round that they remain inside the nimbus. These rounds do not need to be consecutive.
