Well, Genjutsu just might not work
well. The exam will be split into three or more stages, composing at least;
A written phase, which is more of a puzzle than anything else.
A team vs. team phase, which will involve survival techniques and subterfuge more than actual confrontations.
And a tournament-style series of 1v1 fights, which by that point will be more of an epilogue to the game than a real substantial part of it.
At my whim, at any stage between the two phases, an elimination round which might compose of a race/puzzle/mini-tournament might be staged.
As it is, Genjutsu might not work well with the party we have- even if it fits Emi... Also, I find it terribly dumbs down fights. When I GM fights in this system, they are really more like puzzles. You find an enemy's weakness and exploit them, outthink them. Or you figure out how their techniques work and devise a counter to it. Genjutsu is... well, rather boring. Can you see the enemy? Cast a spell! Do they fail a will save? Match complete. If they didn't, try again!
I could simply give every NPC 'Iron Will' or have them burn action points to resist genjutsu, but that's not very fair if your build is centered around it. That and Yoshi already kind of covers these bases.. even if he isn't the big seducer that she is, mechanically they might fill the same role and that will lead to some rather... uninteresting encounters.
In short, I'd really appreciate if you let me in on the process a bit more... Please read over the thread before anything else and think about what niche your character might fit in best. Personality-wise, most. Both characters are kind of chaste (despite my attempts to tempt them
) and frankly I am a little worried about a character just storming in oozing sex and throwing the entire tone set by the party so far off.
