Cluster Bomb

[HeX.16]

Well im busy making a marine hero and need a cluster bomb spell.Im sorta new to the editor and would like some help.
Name:Cluster Bomb
Stats:6 lvls,50 dmg per lvl starting at 50(50,100,150 etc)
Discription:Hero throws multiple grenades at the target area(aoe plz) dealing X dmg per bomb the amount of bombs increases per lvl.The total dmg for all the bombs must = 50xlvl of spell
If u can make it in gui plz do i suck with jass.
Needs to be mui, leakless, and lagless.
If some1 is feeling very helpful can they make the same spell but with flame bombs and not grenades.Feel free to use custom models/effects.I need this ASAP but i wont rush any1.
Thanks to who ever does this and ofcourse +rep.

i would rather like not to because it just doent look at nice as it could.
I just tested with rockets again it looks alright but i would like to throw all the grenades at once and have it so only the units hit the the grenade take dmg.but thanks for that sugestion
