Rivermill Studios A magic defense shield.
The shield is comprised of multiple elements: three orbiting shields (each with particle trails), horizontal shield rings and a ground energy ring which is emitting vertical sparks. Two animating real time lights also complement the effect.
The effect has three stages, with the effect starting, looping and then ending. This is controlled with a custom script with start and stop initially mapped to the left and right mouse button.
Sound effects are included which start, loop and stop to match the action.
