Your study of conjuration is the envy of the magical community, and that school’s deepest secrets are yours to wield.
Benefit: Whenever you apply a metamagic feat to a conjuration spell, that spell takes up one spell slot lower than it normally would. For example, a quickened acid arrow would only take up a 5th-level spell slot (only 3 slots higher than normal, rather than 4 slots higher.)
