How do you make units invunerable?

as the title says

 

[Viggzta]

Temporary or forever?
Forever: Object editor > Units > The unit(ex. Footman) > Abilities - Normal > Add Ability > Invulnerable (Neutral)
With triggers:
Trigger
Events
Unit - A unit enters Region 000 <gen>
Conditions
Actions
Unit - Add Invulnerable (Neutral) to (Triggering unit)

Even if you trigger it, it will be forever.
You can remove invunerability by making it a buff (so the invuln. expires when the buff expires) or you can remove via trigger
Unit - Make <Unit> (Invunerable/Vunerable)
