All 7 tiers.
Relic 7 EP and DV, Relic 1 Thrawn, G12 Death Trooper, Gear 11 IPD.

Edit: this is it. I'm guessing most are higher than your current gear/relic levels but it might help you form a plan with what you have: https://forums.galaxy-of-heroes.starwars.ea.com/discussion/240869/gc-empire-feat#latest
