I am level 23 and I have like 900 life and 600 shield but I am getting utterly destroyed so fast. If it's a group of 3 enemies I pretty much die every time. It seems like they are hitting super hard or somehow I have no life to survive the hits. seems like all it takes is 3 hits and I'm down for the count.

What can I do to improve survivability? I'm playing Nisha.

ORLY? I'm using level 20-23 epics on every slot.

what level are the things that are killing you?

do some side quests, get some levels

Go with more defensive shield if you're not... Turtle, adaptive, or absorb.... Consider resetting skill points and going with something that helps more with survival. Transfusion grenades... Stop being bad? I never had any issue with Nisha. Hardest hump would've been being lvl 42 doing TVHM MK5... He was lvl 47 along with the trash spawns being 45-47. Idk man GL, you'll figure it out.
