Planar Channel (Su)

At 2nd level, a Riftwarden can channel baneful energies against creatures with the extraplanar subtype, regardless of alignment or plane of origin, as the cleric’s channel energy ability. The Riftwarden deals damage as a cleric of a level equal to her highest caster level. This energy can only harm, not heal. This ability cannot be used with feats, magic items, or other effects that modify channel energy. A Riftwarden can use this ability a number of times per day equal to 3 + her bonus for the relevant ability of the spellcasting class she selected.
