Here is an alternate Body of the Sun VFX which I use. It's not exactly a groundbreaking change, but maybe someone else likes it better than the default yellow ball.
It is based on sp_repulsion_fx1.pfx with added flames for legs and arms. Upon casting, a "sun effect" explodes (similar to the default Body of the Sun VFX) on the caster and then disappears.
