The
Friend to Foe spell (PHB2) ....
http://dndtools.eu/spells/players-handbook-ii--80/friend-to-foe--2985/This Illusion [Phantasm] spell first got notoriety as one of Frank Trollman's selections for his infamous "Spells That Fvcking Kill People" list. Beyond that, it's really hard to find any mention of this spell being discussed at WotC, GitP, EnWorld, BG or MinMax forums. Primarily because searching for the words 'Friend to Foe' brings up a lot of unrelated crap finds due to the generic words in the title.
So that's why I'm coming to you folks.
Tell me what you think about this spell. I'm looking at it and loving the fluff, the concept and the sheer social upheaval potential in the spell. But I'm also seeing a a lot of potential headaches and flying by the seat-of-your-pants adjudicating for the DM. Because casting this against a bunch of dumb, angry Hill Giants will net a considerably different result from that of casting it on a bunch of guileful, savvy Succubi once the Phantasm is lifted after damage starts to get dished out.
Perhaps some of you have used this spell or DM'ed players who've cast it? I could use some advice and testimonials. Especially since I plan on DMing soon with an urban/woodlands campaign that starts at 10th level in the Forgotten Realms. And I have one player who is itching to use Friend to Foe with his planned Beguiler build.
