Make a spell that causes two stampedes on the same spot. One is a normal stampede (based off the normal spell), the other affects only allies and heals them. Make it so the two stampedes will always go in random directions.
Yes, this is a roundabout way of me trying to see if you spell you helped me with earlier can be done by someone else :). If you can make a dummy caster that will channel spells, that is all I really need to know.
Thanks ahead of time Pyro.
EDIT: Here is what I want the spell to be:
As long as the dummy spell is based off of channel, and the only triggering is the use of a dummy caster, I am happy. I already did all the other work as it is (text, replacing effects).
GUI is preferred, but if all else fails, JASS will be fine.
