Subtle Spell

When you cast a spell, you can spend 1 sorcery point to cast it without any components, except material components that are consumed by the spell. When you cast a subtle spell, it also does not end effects that would normally end when you cast a spell (such as the invisible or conditions) unless you want it to.
