Just out of curiosity, since I never really bothered testing it: when you play a mage and make him learn other types of spell, like the clerical ones... Is the "chance to hit"/spell proficiency still based on his INT? Or is it a Wisdom check?
Just checked ...
And nope, its Roll+Profficiency+Int Modifier ...
Even for spells where you get amount of Damage or Healing as Dice+Wisdom Modifier is changed to Intellect ... so your Cure Wounds still can do 1d8+3
