Took 2 attempts for 6* Thrawn. 81 Kanan Omega Gs 8, 81 Zeb Omega GS 8, 82 Hera Omega GS 8, Ezra 80 Omega GS8, 83 Sabine Omega GS 9. Sabine only 6* everyone else 7*.
Screwed up on first attempt and went after DTs First instead of Stormtroopers. And was early on Kanan Taunt to take Thrawn’s hit. As long as you time Kanan or Zeb to absorb Thrawn whack a mole you should be good. Sabine does good damage and that dark saber strike is amazing in getting armor down so Ezra and Hera can whittle them down faster.
