I saw Cowboys and Aliens at the cinema yesterday and became inspired by the ailiens' weapons.
This is a blast from an Ion weapon of some sort. It was kinda hard to get a good screenshot of the effect so you'll have to check it out in Magos or even better WE.
The Stand animation is empty on purpose so that it can be used as an Artillery missile.

If anyone can make an animated .gif image of the blast in game I will add it here in the description. My computer can't handle so much action.

Anyways give credits if you use it and don't redistribute.
