editing cloud

i'm trying to create a channeling spell that increases the attack and move speed for all allied units in it's AoE.

i tried editing the cloud spell, changing the affected targets for ground,air,self,friend and gave a negative values (cause cloud fields are for speed reduction), but it affected only enemies and reduced their speed instead of increasing it. tried giving it positive values and nothing was changed.

any help?

You might want to try adding "allied" to the list of affected targets before trying anything drastic.

i did, i put 'friend' in there, doesn't help.

Sounds like a cool way to modify a spell, but it also sounds, based on your testing, like Cloud might only work on enemies and as a penalty. I've encountered the same thing with the Demon Hunter's Immolation ability. You can modify how MUCH damage it does, but you can't make it give life and you can't make it affect allies.

i finally made it using monsoon as the dummy spell (eq always affects allies even if the slow factor is 0 and i didn't want a buff icon to show on the affected units) and made two triggers, one creates an invisble hero unit with modified endurance aura and the other removes it when the channeling is done/cancelled.

still, i would like to know if there is a better way to do this...

Yes, I believe there is a way you don't need triggers. Just make an ability based on tornado and make it summon an invisible, unmovable, unselectable unit that will have the aura. The only thing you may find problematic about tornado is that I don't think you can set it to show an area of effect when you cast it (because it targets a point, not an area).
