Need help, AoE that hit once

[JeffreyQ]

I am trying to create a shockwave ability. Think of it as hellion flame thrower that becomes an ability that can target a point.

When i cast it on a point, a line of fire/explosion will be created. But now, it hits large units more than once (Ultralisk). I tried adding "no markers" in the validator for the damage effect, but still no luck..

Problem in short:
- Hits more than 1 time on units.

I've attach the map below. Will be a great help if anyone can solve this. Thanks in advance!

I can't look at the map atm but from what your saying it sounds like the line of fire damage hits large units more than once because there more in the line of fire than smaller units thus it counts as more hits. You could possibly make a trigger that does something like when units gets hit by (insert attack) then make it so that for the next however long the attack lasts any damage from that attack will do 0 damage.
