Stitch
Unfortunately, he is completely blind and is only good for healing. With his stupid shotgun, he will spend three-quarters of the game staying somewhere in the back. And I also had a bug, his armor and resistances suddenly dropped.
Don't listen to Drakokot, Quick Shot is excellent if you're not leveling up a sniper or some "I shoot in the eye" energy-based character. He is essential for heavy shooters.
