Just released for free a pack with 5 Particle FX. I'm accepting suggestions for more FX to add later on.

Good looking FXs, thanks!
As for suggestions, what about these:
1. Magic projectile + reaction animation when it hits something
2. Ice projectile + reaction animation when it hits something
3. Flame, smoke and poison cloud you've made but blown horizontally
Those ideas are really good! I'll try to create some =D
