Press E to deploy Guardian Angel Beacon, Interact to destroy Guardian Angel Beacon.
I actually suggested this in a rework idea that removes Rez and replaces Valkyrie with Baptiste’s Immortality Field, though the Guardian Angel Beacon wouldn’t have been an E ability/Pistol Secondary Fire… it’d be part of her ultimate that is deployed when pressing Q.
