Minimum gear requirement to beat first tier of Endor Escalation?

I have Chirpa 9, Teebo and Wicket 8, Elder 11 and Scout 10. There are better line ups that can do it with less I think but that's all I have.

And you beat it regularly?

It really hinges on the omega abilities and speed of Logrey and Elder. There are good videos on YouTube which explain it far better.

On the video I watched none of the characters had omegas

And on the second tier you can use any character right?

@Ninjah9 yeah any characters for the bonus tier once you have a 7* Wicket.

Can't remember how many omegas on mine but they are here: https://swgoh.gg/p/493755272/characters/?f=Ewok

I focus on the Walker and ignore then Scout troopers in phase one and three, and usually call Teebo to assist for TMR.

Thanks. I'm going to omega Teebo for the tmr. That seems to be the key to beating it, by using wicket and teebo. Then elder for revives.
