Usually happens when activating it while your character is moving, but it can happen when you are stationary too. Looks glitchy, a bit like animation cancel to me.
Orange blob will appear around you, but there won't be hands & body animations, just a minor body shake.
They way it is now - when animation is not showing - this ability can be spammed. Don't know if this was intent or not, but doesn't look good.
