I was looking at making a kobold wizard when I came across something weird. Spellscale kobold sets your key ability to charisma for arcane spells. This is something that no other racial feat or heritage does:
Seer Elf
Wellspring Gnome
Human's Adaptive Cantrip
Gnome's First World Magic
My question then becomes, if you go wizard or arcane witch, can you make your Key ability for that class Charisma rather than Intelligence? they both set your Key ability, rather than add to it, and since you get a boost to your key ability at character creation, you would be able to get an 18 Cha Wizard/witch.
