I actually think that Amara might be the best character for beating the Slaughter Star 3000. Last night, I tried Amara for the first time on the Slaughter Star 3000, and beat all 5 rounds 3 times (with different modifiers) and only ever died once. I rarely even went down. AND my Amara times are significantly faster than my Moze times. Here is what I tried, is there a build that is published using this stuff yet?:
Guns: Brainstormer (Most Important), Hellfire, and Crossroads.
Legendary Mod: Ledgendary Phaszerker
Action Skill: “Ties that Bind” with “Stillness of Mind”
Key Skills: All cooldown and damage increases and get 5/5 in “Sustainment” for 20% lifesteal.
