Too big effect.. too slow projectile.. projectile launching and end of spell animation not in the same time... too big damage... not interesting for a good map because damage and effect make map unplayable.
.... and take a better model... this look bad, stand 2 and spell are bad.
My suggestions: Increase the casting range to over 1000/make it so it doesnt hurt the caster/both of the above. This spell can be easily called a suicide attack, as even if you cast it on max range youre caught in the explosion and receive damage.
It's not good, it's great I'l think i'l use this spell without credits Just kiding, i will use this spell for shure and with credits, may i can take "Broly all mighty" model? plz
