I tested it out a bit in MAP30. It works well, but when I fire the Snake Staff, I get a massive performance drop when the snake projectile split into several ones. This is the first time I experience it with one of your mods.
I am also getting a slow frame rate when firing the snake staff so I think it should be tone down a bit. And it is not the impact that is effecting it but the trail the projectile leaves behind. But the impact also has a very loud reverb compared to the other weapons.
