A cleric of mine has had excellent success through the middle levels (5-10, basically) with
shatter.
I've found it a useful way to deprive enemies of certain items, including weapons, armor, light sources, carrying capacity items (bags, packs, sacks, boxes, vials [this is nasty: try it with that vial of alchemists fire the hobgoblin grenadier is holding, or the acid beaker in the evil alchemist's lab as the fight rages around you]), as well as affecting windows, certain portals, chains holding or wrapped around objects, etc. Sure, there's a saving throw involved in some of those cases, but it's still not too bad. Not to mention, good against crystalline monsters. It's certainly not a big blaster like fireball, or a healer, or a buffer, but I find it very handy. Obviously, later on at higher levels it's not as effective, but you never know when you'll have to shatter a beholder's (mundane) mirror or something.
The boards need a "thumbs up" smiley.
Thanks,
