Spoil Holy Water

This baneful dweomer affects holy water in the area of effect. All holy water containers in the area of effect are checked, the holy water in a container is spoiled (rendered harmless to evil creatures and unusable as a material component) on a roll of 10 or less on 1d20.

A holy water font or basin and its contents are unaffected unless the spell is focused only on the font or basin alone and delivered by touch. It gives its water +1 to +5 bonus to the roll depending on its material (copper, silver, electrum, gold, or platinum). If the holy water is spoiled, the font is rendered useless until it can be purified and re-consecrated. Unholy water is not affected by this spell.
