Yes, you need to use triggers.

Here is the easiest way to make it (but it has a lot of memory leaks):
- Create a dummy unit to cast a dummy spell
- Create a Shockwave ability without any special effects or damage, this is the ability your caster will use
- Create another Shockwave ability for the dummy unit, it has the damage and special effect
- Create a Firebolt ability for the dummy unit, it must have no missile and damage

For the triggers:

Shockwave Cast

• Shockwave Cast
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Shockwave (With Stun)
  • Actions
    • Unit - Create 1 Dummy for (Owner of (Triggering unit)) at (Position of (Triggering unit)) facing Default building facing degrees
    • Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
    • Unit - Add Shockwave (Dummy) to (Last created unit)
    • Unit - Order (Last created unit) to Orc Tauren Chieftain - Shockwave (Target point of ability being cast)

For Shockwave Cast, when a unit cast the Shockwave (the one without the special effect or damage), it will create dummy unit and cast the Shockwave with damage and special effects to the target area.

Shockwave Damage Event

• Shockwave Damage Event Init
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Unit Group - Pick every unit in (Units in (Entire map)) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Unit-type of (Picked unit)) Not equal to Dummy
          • Then - Actions
            • Trigger - Add to Shockwave Stun <gen> the event (Unit - (Picked unit) Takes damage)
          • Else - Actions

• Shockwave Damage Event
  • Events
    • Unit - A unit enters (Entire map)
  • Conditions
    • (Unit-type of (Triggering unit)) Not equal to Dummy
  • Actions
    • Trigger - Add to Shockwave Stun <gen> the event (Unit - (Triggering unit) Takes damage)

Shockwave Damage Event detects every unit in the map (except the Dummy) and add them into the Shockwave Stun's event.

Shockwave Stun

• Shockwave Stun
  • Events
  • Conditions
    • (Level of Shockwave (Dummy) for (Damage source)) Greater than 0
  • Actions
    • Unit - Create 1 Dummy for (Owner of (Damage source)) at (Position of (Triggering unit)) facing Default building facing degrees
    • Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
    • Unit - Add Stun (Dummy) to (Last created unit)
    • Unit - Order (Last created unit) to Neutral - Firebolt (Triggering unit)

For Shockwave Stun, when the registered unit from the Shockwave Damage Event trigger takes damage from a caster with a dummy Shockwave ability, it will create a dummy unit and stuns the damaged unit.

I added a sample spell in the attachment.

If you are concern about the memory leaks slowing down your map, read:
Guide to Memory Leaks

and the leak for the Shockwave Damage Event can be fixed with this library:

Alternatively you can experiment with Impale since it pretty much does what you want (stun units in a line)

well as I've recently learned there's a spell called breath of frost that does damage in a line and applies a buff.

you can detect damage, look for the buff, delete said buff when you find it and apply a stun. haven't tried but should work.

do not use impale. it has a weird invulnerability state and I'm pretty sure it causes weird bugs if you change like, anything about it.

sorry I am very unexperienced, I don't know anything about making "dummys" , could somebody explain to me how I do that.
Furthermore how can I open the test spell you attached to your post @Glint , because when I download it, it just opens an empty editor map without anything :/

Open the Object Editor (F6).

Create a new unit, in my example I choose a Footman.

Then here are the values to turn it into a dummy unit:

Abilities: Invulnerable (Neutral), Locust
Cast Backswing: 0.000
Cast Point: 0.000
Death Time: 0.10
Model File: Zone Indicator (Custom Campaign)
Shadow Image (Unit): None
Attacks Enabled: None
Death Type: Can't raise, Does not decay
Movement Speed Base: 0
Movement Type: Fly
Food Cost: 0
Sight Radius (both): 200
Name: Dummy

You could try opening it in the World Editor under File > Open Map... then select the map from there.
