Wave spells?

How they work? I can make wave that moves forward but don't know how to do damage. I don't want to use Immolation or buff for check if unit is hit. Is it setting speed to 300 and checking 150 AOE every sec or what?

Do you want to make the spell 100% jass enhanced?

Then I would create a dummy, move it with times, and have a trigger that detected when units came in range of it, and then damage the units.

You can create a group when the spell is cast, and then keep on picking all units in range everytime the missile is moved. If the units then are NOT in the group, add them to it and damage them, if they are already in the group, do nothing.

Blade - you are closer to 2 blue bars :)
