The problem is the Arcane exploits and their DC.
You have written it as:
“Unless otherwise noted, the saving throw DC for an exploiter wizard exploit is equal to 10 + half the wizard’s level + the wizard’s Intelligence modifier.”
But in game it works as Pen and paper.
Pen an paper has this working as the Arcanist, with Charisma as the modifier used.
(had to rewrite this so many times as I go back and forth to test things and look up how it works in pnp. xD went from a huge “this is not working” to a simple typo! lol)
