How to make Metamorphosis passive?

I didn't know where to post that thread, so I posted it here.


I want to make passive Metamorphosis. I mean, when i add this skill, hero changes his form(for free, no mana cost, no clicking). Do someone know how to make that?

Do you want it to be permanent, or not?

Yes, permanent.

You want to add an ability based on Chaos to your unit that turns it into a demon hunter model with the alternate animation set. And you should post development questions in the general development forum.
Moved.

Sorry that i haven't told but I don't want Demon Hunter metamorphosis. I want to make orc warlock transform passively to fire lord.

Then it's the exact same method just your starting unit is an orc warlock and the ending unit is a firelord.

Can you explain me how to make that step by step? Because I don't know how to do that.

Make an ability based on Chaos. Set your starting unit as an orc warlock. Set your ending unit as firelord. Add chaos ability to the orc warlock when you want it to change.

Done.
