Pressing Q activates a giant green forcefield around the user that will block any incoming projectiles and prevent players from coming any closer to the user by repelling them upon contact, while also rapidly healing the user if they are damaged. You can easily counter this by using the swords laser. It has also been discovered that when a projectile comes to the shield, it auto aims it to the nearest player.
