Tainted Scholar—Warlock Archetype
Restrictions: Single class only.
If you use this archetype, you use Intelligence as the Warlock’s primary ability score, rather than Charisma. Your spellcasting ability is Intelligence instead of Charisma, and any Warlock feature, Pact feature, Eldritch Invocation, &c. that normally uses Charisma uses Intelligence instead. You gain proficiency in Intelligence saving throws instead of Charisma saving throws.
(This archetype is slated for future expansion. As of right now, it’s kind of boring.)
