(All)
(Alteration)
Area of Effect: one weapon
Duration: 1 round
Casting Time: 2

This orison blesses any single weapon temporarily, imbuing it with divine power for one round. The weapon is considered to be magical, and imbued with your deity’s alignment, for the purposes of bypassing certain creature’s defenses and damage reductions. This spell does not convey any bonuses to hit or damage.
Missile weapons do not confer this blessing onto their ammunition. To bless such a weapon, the ammunition itself must be blessed. You can bless one item of ammunition. Once the ammunition is fired, the blessing is lost on that item.
