I have my players stuck in a dessert where a genie grudge match is taking place and at the end of last session they met the Janni involved, well he is honestly apathetic to the whole thing but he is stuck here until its resolved.

Anyways I was thinking of playing him up as an illusion specialist and as much as it shames me I have never realy used illusions in my years of playing so Im not sure how to do this, I know I can just DM hand wave 'It was all an illusion, ohhhh' but I think this could be handled within the rules.

So Im thinking an 3 levels of an Illusion school wizard banning transmutation and necromancy.

Any thoughts, guidance, traps to watch out for would be greatly appreciated.
