If you could be able to work one spell without a wand, what would it be?

Accio!
I mean, who doesn´t want thing flying to their hands just by naming them? Every lazy ass person like we are :))

Expecto Patronus! I feel like if dementors are coming at me, then it would be useful to protect myself without my wand. Also, I just love the Patronus Charm.
