Thanks for your feedbacks! :D I love your idea, Simplastic, I'll give it a try. :3 Thenderson, I'm not sure what you mean by the "fireball" here... I completely agree for everything else you said, but I don't really see what's the fireball in my vfx. :p A quick test of what I think you mean: Basically just switching most…
Also, for your symbols idea: instead of the charging fireballs in an arc, you could do a few symbols with a firey texture, then use distortion to give it the illusion of movement and heat. So you would have a flame symbol in the place of each fireball, scaled about the same, that flickered and waved a little
I think if you move up the cloud/offense part of the spell farther above the sphere you will get some better readability, and your effect will look less squished. It seems like a lot of your hard work isn't as visible as it could be. Especially seeing how far up the user/channel goes.
