Eradication (Su)

At 3rd level, a Riftwarden gains a +1 sacred bonus on saving throws against the spells and spell-like, supernatural, and extraordinary abilities of outsiders. In addition, she increases by 1 the save DC and caster level of any spell or spell-like or supernatural ability that she uses against outsiders, or that counters, dispels, or prevents planar travel or teleportation. These bonuses increase by +1 for every three levels after 3rd.
