The focus replaces the Material (M) component of a spell, but if a spell states that a material component is consumed by the spell, the caster must provide this component for each casting of the spell.
Thanks that's good info. Wasn't sure of the point of an Arcane Focus + Spell Components. Instead of makes sense. It will help a lot when I play my Evoker/ Artillerist build. Well after the Artificer gets modded in.
