[Solved] How to Make This Ability MUI?

[Hermit]

I'm trying to make a passive ability that increases the unit's attack rate by 75% and movement speed by 50% for 12 seconds whenever its hit points fall below 25% of its maximum HP. This effect can only occur once every 120 seconds.

I want the ability to have a visible cooldown, so I based it on Exhume Corpses, since it's the only passive ability (that is not attack-based) which can have a visible cooldown that can be triggered at any time.

The ability should NOT activate while it's on cooldown. The speed boost should NOT be dispellable and should NOT disappear if the unit is healed above 25% HP during its duration.

Most of the triggers below were copied from somewhere in an attempt to make this MUI, but they're presumably completely nonsensical since I don't really understand the logic behind it; I just know that it doesn't work properly.

P.S. I know I should probably use a damage detection system in the second trigger, but in this case the "A unit is attacked" event is good enough as a placeholder, until I decide which DDS to use.

Not sure which version you're using, but in the newer patches you can trigger the cooldown for Exhume Corpses like so:

• Unit - For Unit (Triggering unit), start cooldown of ability Adrenaline Rush (Exhume Corpses) " over "120.00 seconds.

Then you can move the Actions from AR Add Bonuses to AR Cast (You could actually do this now and save yourself a trigger).

Also, in AR Loop, you want to Remove the speed abilities from AR_Caster BEFORE you change the rest of the variables. So move those 2 actions to the very top of your If Then Else.

With those changes it should work fine.

And this method is called dynamic indexing, there's a link to it in my signature. Here's a poor explanation:

Let's say 3 units are affected by Adrenaline Rush.
In this case AR_Index will be equal to 3 and AR_Loop will loop from 1 to 3 every 1.00 second.

When AR_Caster[1]'s duration has completed, AR_Caster[1] is set to AR_Caster[3], AR_Counter[1] is set to AR_Counter[3] and AR_Index/AR_Loop_Integer are reduced by 1.

As a result of this, AR_Index is now equal to 2 and AR_Loop will loop from 1 to 2.

Since AR_Loop_Integer is reduced by 1, the Loop will actually run through the same Index again. So it just finished looping through Index 1 of 3, and now it will loop through Index 1 of 2.

But this time it won't reference the original AR_Caster[1], it will instead reference AR_Caster[3], since we've set AR_Caster[1] to be equal to AR_Caster[3]. Same goes for AR_Counter.

Then once AR_Caster[3] (aka the new AR_Caster[1]) is completed, the process will repeat, but this time setting AR_Caster[1]/AR_Counter[1] to AR_Caster[2]/AR_Counter[2].

This process repeats on and on until the very last unit is removed from the Loop.

For the last unit, AR_Caster/AR_Counter [1] would be set to AR_Caster/AR_Counter [1], which obviously doesn't do anything. That's fine since AR_Index would be set to 0 and the trigger would be turned off.

I'm using patch 1.29.2; I can reset the ability cooldown and set it to a specific value, but it looks like I can't make the cooldown start on its own without using the ability.

I've heard of dynamic indexing before, but it always seemed too complicated for me until now. Thank you so much for the detailed explanation!
