What exactly supports Mirage Warriors?

I am getting conflicting information online (and from Gemini 3). I am hoping some experts can answer some questions.

I am using Tawhoa Felling to proc 2 Mirage Warriors to slam for me. I know supports like Multi-strike, Ruthless and Fist of War don't work on them. What about Immolate support?

What are the supports that can enhance their damage? AI told me nothing increases their damage. True?

Critical Hit and Damage?
Fire Penetration?
Melee Physical support?

Yes. I read that page already. It doesn't tell me if other gems are working or not. I switched Immolate support to Critical strike and I feel Immolate wasn't working for my Mirage. That's why I am posting here.

Basically, you read what a support does, and if there’s nothing indicating it won't work, then it works. For that you should know Tawhoa's Chosen mechanics, mainly two points:
1. Mirage chietains use the attack they were triggered from.
2. Mirage chietains disapper after one attack.

– Fist of War: "Only skills you use yourself can receive the boost" (check point 1)
– Ruthless: "Every third Attack with Supported Melee Attacks deals a Ruthless Blow" (check point 2)
– Multistrike's AS boost and damage penalty should work, but not the repeat part, because mirage chietains are too busy disappearing after the initial attack animaton.

They all work. And Imolate should work too.

You increase their damage by increasing your damage, you can't increase just their damage separately. Mirage chietain is like your copy that have only one attack (your attack with your stats) and lives only one attack.

Thanks!
