Rotsbane

This spell enchants a wooden weapon (including arrows) with a powerful animosity for the undead. It will cause a significant amount of bonus damage against them, and also has a chance of rendering them unable to naturally regenerate hit points for a short period of time. This will additionally cause the weapon to become poisonous, offering it some efficacy against the living as well. It is not possible to cast this spell on a weapon that deals disease damage, whether it be temporarily or permanently.

One may place this spell upon a wielded weapon by casting it upon a person. Those affected by the Gamalean emissary spell will be considered as undead for the purposes of this spell.
