Description

Other Information
Whatever alignment you make the weapon/projectiles determines the alignment of the spell. Can't be cast on a natural weapon.

Pros:

Allows you to bypass alignment-based DR, which is otherwise a significant disadvantage.

Cons:

Useless versus most opponents.

Won't work on magical weapons that have alignment (which unfortunately are usually strong weapons).

Tricks/Combos:

Not really a combo, but your Knowledge (Religion) and Knowledge (Planes) skill checks should be high if you want to use this spell, otherwise you'll never know what kind of DR a particular fiend or celestial (or whatever) has.

Overall:
A good spell that you will very rarely use. If you find yourself about to travel to a different plane, ask your DM if you can make a prepatory Knowledge check to estimate if you'll need this spell.

Recommended for Clerics?
Not unless you know beforehand you will be facing something with alignment DR, in which case it's a no-brainer.

Recommended as a scroll?
Yes. Align Weapon is perfect as a scroll, for those situations where you find yourself against an unanticipated foe with alignment DR.
