  This spell was created by the paladins of the Mendevian Crusades, and co-opted by inquisitors and rangers dedicated to tracking and fighting demons, devils, and other evil extraplanar creatures.
  When you cast this spell on a melee weapon you imbue it with a powerful holy energy, granting the weapon the bane weapon quality against evil outsiders. Furthermore, whenever you score a successful critical hit against an outsider with the evil subtype, you not only deal normal critical damage with the weapon but also nauseate the outsider for 1d3 rounds-the outsider can reduce this Nauseated condition to Sickened for 1 round with a successful Fortitude Save.
