Team: Emperor Palpatine (L), Darth Vader, Grand Admiral Thrawn + 2 Empire Characters.
Tactics: You only need the first 3 characters for this to work, add 1 or 2 more if you want to play it safe. Fracture Mission; use Force Crush + Culling Blade with Vader on the most debuffed enemy. Spam Aoe stuns with Palpatine. Pro tip: Make sure Zaalbar has Shock on him so he doesn’t taunt.
