Your studies into how all things are interconnected have taught you to cast a very limited number of spells.
Benefit(s) Select a single spell from the sorcerer/wizard spell list that is at least 2 levels lower than your highest-level extract known. You can prepare and cast this spell as an arcane spell. Preparing the spell uses up an extract slot 1 level higher than the spell’s level. Your caster level is equal to your alchemist level, and your save DCs and concentration checks are Intelligence-based. You’re considered to have this spell on your spell list for purposes of prerequisites, spell completion items, and spell trigger items.
You may select this discovery more than once. Each time, it grants you access to another spell from the sorcerer/wizard spell list.
