[Trigger] Magic Resistance Aura

[Lordul Dracula]

Hello I want to make a skill that : summon a frost core that will make all your units in the range of 500 magic resistance by 20% and enemy units -10% move speed and -15% attack speed in the range of 150
I added 2 aura to that frost core , 1 slow aura for -10% move speed and -15% attack speed in the range of 150 and another slow aura just for the buff

Can somebody help me with this aura?
I'm using Warcraft 3 1.30.1

You're only Adding nearby units to the FrostiumCrystal Unit Group when you first cast the spell.
You want it to work like an Aura which will affect and Add new units that come within range of it.

So instead you should add your Frostium Crystal to the Unit Group, and then Periodically check for Allied units near the Crystals. If those units are allies of the Frostium Crystal (and you probably want to filter out Dead units / Structures / Mechanical) then give them the Magic Resist ability.

Removing the Magic Resist ability from your allies is a little bit tricky because you'll need to also track these units as well. You can do this with a second Unit Group which periodically Removes the ability if the Picked units don't have the buff.

Then you'll probably want to turn off the Periodic trigger once FrostiumCrystal is empty to keep things efficient.

Thx for your reply. I will try your solution after work.

[Uncle]

No problem, here's some issues I see:

You forgot to add this Condition to your Pick Every Unit functions:

• (Level of ..Frostium Crystal (magic resis) for (Picked unit)) Equal to 0

This will prevent units that already have the Magic Resist ability from being targeted again.

And in the Crystal Dies trigger you need to Remove Frostium Crystal (magic resist) not Add it:

• Loop - Actions
• Unit - Remove ..Frostium Crystal (magic resis) from (Picked unit)
• Unit Group - Remove (Picked unit) from FrostiumCrystalGroupAllies

Thx I fixed those issues
