[Trigger] Three Way Artillery

[Davy Jones]

I would like to trigger an artillery that after impact spawns 3 projectiles which jump in three directions.
First the unit attacks. I added it a Disease Ward ability that spawns the invisible dummy unit that has the artillery attack.
Now I want to trigger that unit to attack in 3 different directions.
The problem is, I can't identify it. A unit enters (Playable map area) or A unit spawns a Summoned Unit (then unit type equal to (dummy) blahblah). How do I make it identify it.

ATM the trigger looks like

• Events
  • Unit - A unit enters (Entire map)
• Conditions
  • (Unit-type of (Triggering unit)) Equal to Shattering Shot

• Events
  • Unit - A unit enters (Playable map area)

Won't work as well.


Also how can I make the unit attack ground 50 units forward, 50 units at 135 and 270 degrees?

NVM figured it out.
