[Trigger] Multicast spell triggers

[vickyocc]

Can any1 teach me how to make a spell like in Dota's Ogre magi? the ulti, multicast. The ulti is dam nice when it can multicast some other spells

The spell can be based on any passive spells rite?

You make a dummy and order it to cast spells (at the same time)

I will just write how it works.
You base that "ulty" on some aura lets say endurance, than you make it so that only applies on your hero, give it a buff and name it lets say "endurance aura"<-simple

Than you make a trigger that if your hero have the buff "endurance aura" and it casts a spell spell1 or spell2 or spell3 and random integer(this will give you a %[chance]), than make dummy and give it all abilities and order it to cast them.
Ofc. this is just my lame idea D:

Engineering upgrade is a nice idea, cause it allows you to replace the single cast spells.
