Source: Dragon #337
You channel your purifying abilities into your weapon.
Prerequisite: Ability to cast remove disease as a spell-like ability.
Benefit: You can spend a weekly use of remove disease to make a melee weapon you hold either +1 undead bane or +1 vermin bane. If the weapon already bears an enhancement bonus, the bonuses do not stack. This ability lasts for 1 minute.
