i would like some help on how to create a floating fireball/frost/shock summon that shoots the element (explained inside)

i would like to create (or request) a summonable fireball/frost/shockball that would shoot out the element

so the floating fireball would shoot fireballs at the enemy and the other elements would fire similar projectiles.

i thought about using the flame atronach as a base and replacing the skin with the "MAGINVfireball" static and for the other elements "MAGINVfrostspell"/"MAGINVshockspell" respectively.

by using flame atronach it would have the most realistic movement(would really like it to stay near me). allthought i just got as far as starting to edit the duped atronach npc

to give you a better idea think of an elemental candlelight that fires a fireball/ice spike/shock spell

if someone would (teach me how/create it yourself/link a similar mod) i would be grateful because this would be very handy for my characters class
