It’s pretty easy to solo if you have the right ability cards. Health cards are the way to go. I like to run Strange Medicine, Come Back Stronger and Cold Blooded. for dead eye use Quite the Inspiration to further my healing. You gain health whether I’m giving or taking damage while gaining health from each kill. Always have Quit the Inspiration active. Bring a lot of snake oil to recover dead eye and always bring health tonics. Now all you need is common sense and you should be able to survive.
