Well I'll try to make the beams look wilder but about the shockwave particles... I purposely used the texture because it doesn't meant to be "real" since I've never seen an arcane explosion in my life before. This is also the reason why I love to make effects because it's appearance doesn't have to fit with the "reality". If you make every effects based on reality appearance or logic, then there'll be no space for imagination anymore. (Sorry for my bad english)
I apologize if you find this comment offensive. Anyway, thanks for your comments
Edit: I'm wondering how to make the beams look wilder...
