Yeah, it’s just a particle effect w/ blue to red color transition and a world collider. Actually it’s two particle effects. One has a fair number of particles w/ a world collider, the other has just a couple particles with world colliders and callbacks to determine damage. It was done this way because having a ton of callbacks slows it down some.
