With your setup, it sounds like the rakshasa would be on the wrong foot and really casting about for options. Illusion-wise, it might do something simple like illusion-up two of their NPC allies to look like it's rakshasa kin "revealing" that they've lead the PCs into a trap.I like the trait idea. That allows me to craft something on a rakshasa by rakshasa basis. The party has already determined that their target is, in fact, a rakshasa in disguise. With the help of some npcs, they have lured him I to a trap and are about to engage him in combat.
The party consists of a warlock, wizard, knight, rogue and that class with spirit companions whose name I can't recall at this second. This rakshasa is a warrior, but the other two are controller and artillery types.
I'd like to give the party options to set up traps and fights that are smart and reward preparation and fun choices.
For mechanical function, maybe it can't be hurt until the illusions have been disbelieved (or it takes bonus damage once they're down). Or maybe, until they're disbelieved, killed, or dispelled the illusions are able to deal actual damage.
If they haven't lead them into the ambush itself yet, you could also make a specific area in town bad for the rakshasas (like a temple that negates one of their powers). So they're guarded about going there, but also can't completely avoid it without blowing their cover.
Cheers!
