All class abilities referencing Intelligence(except for skills) now use Charisma.

Spell Recall recovers a spell slot of the appropriate level instead of a prepared spell.

Knowledge Pool lets you prepare and cast one such spell. It still takes up the spell slot.

Improved Spell recall lets you recall one spell from your spell list, even if its not on your spell known.
