I found a spell called Banosh Shadow in a D20 book. It lets you banish a shadow (the monster) to the Plane of Shadow. Similar spells would bansih demons, etc.
I'm not sure how to build the spell with the Player's Companion spell creation rules. I looked at every spell type, inluding summoning. The spell types don't include an Abjuration category, except protection, whioh doesn't seem to covefr banahing creatures. How can I build a spell that banishes a dreature on a failed save? The spell in question deals 3d4+1/level (max 10) damage even on a successful save. I'd like to include that as well, but mainly I'm looking for a way to banish creatures.
It's kind of like Dispel Evil, but it's not actually clear how Dispel Evil was built. So, have to agree with Aryxymaraki above. Looking at Protection spells just now, wards v certain monsters cost 3, and wards v monster types cost 6. Modifier for "only shadows" could be as good as x.5.
The movement spell categry includes the option to teleport unwilling creatures. Unfortunately, it's a bit weak on extraplanar travel, but "making something go away" is definitely in scope.
Also, there's one important function difference between "dead" and "banished" - "banished" is something players might cast on themselves as an emergency escape, as long as they have some means to return to their own plane later on.
There are two copies of this thread, and the second one redirects to this one... Which is a pain, because it shows up as a "new" thread and I can't view it to make its new-ness go away, so I keep thinking there are new posts in this forum when there aren't. Is there any way I could make it stop telling me it contains unviewed content?
I had the same issue, using the "forum tools" dropdown at the bottom of the topic list, and selecting "Mark all topics as read" seemed to fix it (note it will clear everything, so best done after reading your other new posts first). Hope that helps.
