Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General What can boost a Character attributes?

Am at Hunter's Edge now, 7 codexes on my Wizard.

+7 intelligence, for a tradeoff of -6 perception (She has a base of 6. Waste of that 6th point, but didn't know the item during character creation).

Wonder how insanely high I can pump her intelligence.
