Tric (Valefor)

Before you cast this spell, you decide on whether or not to concentrate on it. Afterwards, target a creature within range, attempting to confuse their mind. Your target must make a Wisdom saving throw, made at disadvantage if you choose to concentrate on this spell instead of normally casting it. On a failure, a creature is charmed. While charmed in this way, the charmed target can still act normally, but until the end of the creatures next turn (or until you drop concentration), all creatures within 10 feet aside from the caster become invisible to the target.
