Trying to think of a reason to stay high Int on an Arti with the change to the capstone. Spell DC's seems limited, because getting them to sustainably nuke at high level is going to take a lot of work. An Int of 20 will still cover a lot of the other perks.
Any thoughts/rationale out there as to why an Arti should stay high Int? Or have they officially crossed over to about as limited as bards with high Cha?
