DLC is beating my ass

I’m almost level 200 and I was super confident about my abilities so I decided to buy the DLC, thinking it would be challenging but like not impossible. I was so wrong. A normal group of enemies in the DLC feels like fighting a low level boss. Like why do these shadow skeletons in the gravesite plain take out half of my 65 vigor health bar in only a few hits??! Feels like I paid $40 to cry lol. Of course, I’m still enjoying it though.

Edit: Thank you for all the info on those fragments I needed to collect. I had no idea. Also, I’m not trying to complain about the DLC. I’m enjoying the difficulty, was just super shocked.
