Paladins are always seeking out evil to vanquish in the name of their god. Some focus on seeking out those that lurk in the shadows, turning back the tide of darkness by invoking the brilliant light of divinity.
At 4th level, the shadow banisher gains the ability to create a brilliant flash of light to either strike at the evil before her or to dispell the darkness about her. This ability is similar to channeling positive energy, but instead of healing living creatures and harming undead, this blast of divine power can only harm undead and create light.
Channeling light causes a burst that affects all creatures in a 30-foot radius centered on the shadow banisher. When used to harm undead, it functions identically to channeling positive energy, and counts as such for feats, abilities, prerequisites, and so on that use channel positive energy.
Instead of harming undead with this energy, a shadow banisher can instead use channel light to dispel darkness. Any 1st level or lower spell with the darkness descriptor in the area is dispelled (as dispel magic). The level of darkness spells that can be dispelled with channel light increases by 1 for every two levels beyond 4th, up to being able to dispel 9th level darkness spells at 20th level. Whether the magical effects are dispelled or not, the area brightens, as a daylight spell, for 1 minute.
A shadow banisher may channel light by expending two uses of her lay on hands ability. Doing so is a standard action that does not provoke attacks of opportunity. A shadow banisher must present her holy symbol to use this ability.
This ability replaces channel positive energy.
At 8th level, the shadow banisher becomes immune to magical aging effects and adds her Charisma bonus (if any) as a bonus to her touch AC. Allies within 10 feet of the shadow banisher add the shadow banisher’s Charisma bonus as a bonus to touch AC. This bonus cannot make her touch AC go above her normal AC, nor can it make an ally’s touch AC exceed their normal AC. This aura functions only while the shadow banisher is conscious, not if she is unconscious or dead.
This ability replaces aura of resolve.
