Bladestorm makes the caster magic-immune. You should decide how this spell should generally affect magic-immune units or if Bladestorm spell is an exception.
I don't think there is any fool-proof way, but since Bladestorm makes the caster magic-immune for the duration of the spell, you could just assume that the unit is currently casting Bladestorm if level of bladestorm ability > 0 and the unit is magic-immune.

If (All Conditions are True) then do (Then Actions) else do (Else Actions)
- If - Conditions
  - (Level of Bladestorm for your_unit) Greater than 0
  - (your_unit is Magic Immune) Equal to True
- Then - Actions
  - -------- is casting bladestorm --------
- Else - Actions

To interrupt bladestorm, you must pause and immediately unpause the unit

Unit - Pause your_unit
Unit - Unpause your_unit

---
As for the trigger itself, there are few things that could be reworked:

You should use event 'Unit starts the effect of an ability' as that trigger fires when mana is drained and spell cooldown starts. The Begin casting/channeling are not often used as they fire before the 'starts the effect' event
You leak locations. Basically every (Position of some_unit) creates a location that must be destroyed via custom script, see the first post in this thread: Things That Leak
You also leak unit groups: Any time you use a 'Pick every unit' actions and you don't refer to a unit group variable, then you create a fresh new unit group which will leak if not destroyed.
- So this is safe
  - Unit Group - Pick every unit in ULT_DummyArea and do (Actions)
- But this leaks unit group:
  - Unit Group - Pick every unit in (Units within 300.00 ...
Inside the inner-most 'Pick every unit' action: you create a fresh dummy unit, give it Petrify Dummy ability and order it to cast. But you do not remove the unit anywhere, basically causing a unit leak
The first 5 dummy units created at the start of the trigger (and added to ULT_DummyArea) seem to be only used for detecting units within 300.0 range of their position. What you can do instead is just use 2 point variables and offset them inside a 'for each' loop action like so:
- - Actions
    - Set VariableSet casterLoc = (Position of (Triggering unit))
    - For each (Integer A) from 0 to 4, do (Actions)
      - Loop - Actions
        
        Set VariableSet offsetLoc = (casterLoc offset by ((Real((Integer A))) x 200.00) towards (Facing of (Triggering unit)) degrees.)
        
        Custom script: set bj_wantDestroyGroup = true
        
        Unit Group - Pick every unit in (Units within 300.00 of offsetLoc matching ...) and do (Actions)
        
        Loop - Actions
        
        -------- creates dummy here and orders it to cast the Petrify dummy spell --------
        
        Custom script: call RemoveLocation(udg_offsetLoc)
    - Custom script: call RemoveLocation(udg_casterLoc)

Ayo, i didn't expect that i don't need to create 5 dummies to do it especially my trigger leaks. Thanks for helping me out right there.
Ummm can i ask for another help from you?

In the section marked as "--- Special Effects ---" you create 178 units (Dummies).
Creating that many units is likely to cause lagg and from what I see, you only use the dummies in order to get their location? Do they do something else?
Also, you're leaking a ton of locations. You can fix the point leaks by storing the points in variables so you can clean them up.

Actions
- Set Oda_SS_Caster_Point = (Position of Oda_SS_Caster)
- For each (Integer A) from 1 to 36, do (Actions)
  - Loop - Actions
    - Set Oda_SS_Vfx_Point = (Oda_SS_Caster_Point offset by 1500.00 towards ((Real((Integer A))) x 10.00) degrees)
    - ...
    - Custom script: call RemoveLocation(udg_Oda_SS_Vfx_Point)
- Custom script: call RemoveLocation(udg_Oda_SS_Caster_Point)

My trigger here also gets the location without creating a dummy. If you can get what you want without dummies, it will likely solve the lagg-issue.

Nichilus · May 8, 2023

Yea, the main issue will be what ThompZon wrote. Units take a lot of WC3's resources, so creating ~180 units in one go is bound to cause some serious fps drops.
Leaks aside, the other thing is that you are also creating 2 special effects per created dummy, so a total of ~360 effects in a rather small area. Effects may also cause some fps drops, even more so for effects that have lot of particles/smoke, etc.

So the basic idea should be that you store caster's position in point variable and inside loop you create a new location which is offset from the caster's location and assign that to a variable (the action that does that is called 'Point with polar offset'). Then you create special effects using that offset location.

Getting rid of the dummy units and resolving those location leaks should help you somewhat. You also leak unit group again at the end of the trigger (where you deal damage).
I don't think you can optimize this more, apart from lowering the amount of special effects that you create (but you should probably take a look at it after resolving the above mentioned issues).

As for the trigger's readability, I would split this trigger in two: One trigger has the loops in it and second trigger creates the special effects.

Effects Trigger
- Events
- Conditions
- Actions
  - Special Effect - Create a special effect at offsetLoc using ...
  - Special Effect - Destroy (Last created special effect)
  - Special Effect - Create a special effect at offsetLoc using ...
  - Special Effect - Destroy (Last created special effect)

Actions
- Set VariableSet casterLoc = (Position of (Triggering unit))
- For each (Integer A) from 1 to 36, do (Actions)
  - Loop - Actions
    - Set VariableSet offsetLoc = (casterLoc offset by 1500.00 towards ((Real((Integer A))) x 10.00) degrees.)
    - Trigger - Run Effects Trigger <gen> (checking conditions)
    - Custom script: call RemoveLocation(udg_offsetLoc)

Also, you may want to limit the number of loop iterations you do. The first 3 loops all run 36 times, they just create the special effect at different offset from the caster, so you may as well merge those together:

Actions
- Set VariableSet casterLoc = (Position of (Triggering unit))
- For each (Integer A) from 1 to 36, do (Actions)
  - Loop - Actions
    - Set VariableSet offsetLoc = (casterLoc offset by 1500.00 towards ((Real((Integer A))) x 10.00) degrees.)
    - Trigger - Run Effects Trigger <gen> (checking conditions)
    - Custom script: call RemoveLocation(udg_offsetLoc)
    - -------- ---- --------
    - Set VariableSet offsetLoc = (casterLoc offset by 1300.00 towards ((Real((Integer A))) x 10.00) degrees.)
    - Trigger - Run Effects Trigger <gen> (checking conditions)
    - Custom script: call RemoveLocation(udg_offsetLoc)
    - -------- ---- --------
    - Set VariableSet offsetLoc = (casterLoc offset by 1100.00 towards ((Real((Integer A))) x 10.00) degrees.)
    - Trigger - Run Effects Trigger <gen> (checking conditions)
    - Custom script: call RemoveLocation(udg_offsetLoc)

Yes, they only use for location @ThompZon ; I'll try to make it later @Nichilus ... Thanks guys

By the way, about this one. The unit that casted Bladestorm seems to not been able get petrified after being PauseUnpause, was there any solution for it?

Nichilus · May 9, 2023

Just tested it and you are right.
The bladestorm gets interrupted, but the unit retains magic immunity for about 0.01 seconds.

A possible solution could be that anytime you detect a unit actively casting bladestorm, you pause/unpause the unit and add those units into a unit group. After the 'Pick every unit' action where you petrify units start a one-time countdown timer with expiration time of 0.02 seconds.
Create another trigger that fires when the timer expires and inside this trigger pick every unit in the unit group where you placed units with bladestorm. At this point they should no longer have magic-immunity, so you can create a dummy unit, give it petrify spell and cast it on those units.

The problem here is that the second trigger will not have a triggering unit, so you would need to store reference to the caster somewhere. I would suggest using hashtables.

The trigger flow could be as follows:
In the 'Petrify' trigger:

Trigger starts when a unit casts Petrify
Pick all units within 300.0 of the petrify points
1. if picked unit is actively casting bladestorm, interrupt it and add the unit to 'DelayedPetrifyGroup' unit group, store reference to Triggering unit in hashtable, using child key 'PetrifyCaster' and parent key = handleId of the picked unit
2. if not casting bladestorm, create dummy now and petrify the picked unit
Start a 0.02 timer

In 'Petrify Delayed' trigger:

Trigger starts when timer expires
Pick all units in 'DelayedPetrifyGroup' unit group
For each unit load the reference to the petrify caster from hashtable, using the same parent/child keys as used in previous trigger
Create dummy give it petrify spell, cast it on picked unit
Remove picked unit from the unit group

I can't follow, can you show it to me via trigger? (Sorry for the late reply)
