At 20th level, an antipaladin becomes a conduit for the might of the dark powers. His DR increases to 10/good. Whenever he uses smite good and successfully strikes an good outsider, the outsider is also subject to a banishment, using his antipaladin level as the caster level (his weapon and unholy symbol automatically count as objects that the subject hates). After the banishment effect and the damage from the attack is resolved, the smite immediately ends. In addition, whenever he channels negative energy or uses touch of corruption to damage a creature, he deals the maximum possible amount.
