I want to give the "Hardened Shield" passive ability to a custom unit having the zealot's model.
How do I achieve so?
I've made it in his Command Card as Passive, but when I start the map, it's grey'd out and not working
None.
Add the ability to the abilities area above the Command Card?
I do stuff and thingies... Try widening and reducing the number of small nooks and crannies to correct the problem.
Hardened Shield is a Behavior and not an Ability.
Adding it to the Command Card is only a cosmetic effect. You need to add the behavior to the unit.
depends how you want to activate it,
None.
