Okay, so as a Jester, your main attack will be Bop. After a bit of research, like only a little bit, I found that Bop gets more damage as you spend more lessons in Pranks..... I think. I'm not entirely sure. Like, at all, heh. Does STR. come into play with Bop, ornah? And does the efficiency with Tarot cards, like High Priestess, depend on Int., or is it possibly like Bop, where the higher the skill, the better it is?
So, if it does depend on skill level, then would Dex. have anything to do with like, the flips and stuff of that nature? If not, then I would go with a Con. max if stats don't come into TOO much with Jesters like an Int. maxed Magi or Str. maxed Monk.
Edit: By efficieny with Tarot cards, I mean like the High Priestess heals you more or Magician gives more mana.
