No, it’s not just EOS. He’s fodder.
Go to the Mutator Arena. Set it to Level 9. Complete the first two waves. If you are lucky, Shadowtrap will not appear. If you are unlucky, A black hole that will absorb every bullet you can possibly shoot without taking a Dent to his shield, which he recharges, and is tiny compared to his Health, will appear.
I have been fighting this guy for so long, that i have run out of ammo on every gun i have, and i havent even gotten his shield down once. It’s not that i am using a bad Build, i got 999 Maelstrom stacks and unloaded a Badaboom in his face. Several Times. It did NOTHING.
Has anyone beaten Shadowtrap on level 9?
