True Caster Revised (5e Feat)
From D&D Wiki
Prerequisites: The ability to cast at least 1 spell.
Your connection to magic has grown powerful enough to bypass the focus you used to need.
You no longer require a focus to cast any of your spells that take an action or bonus action to cast. You also no longer require material components for spells if those material components cost less than 1 GP (Or have no defined cost because of how cheap they'd likely be) and aren't consumed by the casting of the spell.
