The theory

A mix of tank and one shotter (Use Ur to one shot [Sek's armor reduction from tertiary can help it as well], use Sek if you cant one shot). Tertiary is important for both survivability (Ur's tertiary deals damage reduction) and faster/easier killing (Sek's tertiary deals armor reduction) so make sure to use them regularly (Ur's tertiary also deals good damage for crowd control).

I managed to hit level 283 in wrangler but my game crashed because of the constant spawn of small duplicating lesions, im sure it can go over 300 if your game doesnt crash.

Note: Be careful with the enemies that has one shot potential, Ur-Sek's passive ability "Symbiotes" will keep you alive against constant small damage, but it cant keep that up if you are taking high damage
Note2: At higher abyss, dont switch to Sek if there is too much tanky or one shot potential enemy, because Ur has 1 permanent armor stack which helps a lot when your flickering perk is in the speed mode

I honestly think we need video required and manual verification for high abyss claims on wrangler, man. It's way too easy to fake this by playing collector all the way up then switch it to wrangler and screenshot you at a high level. There's no video here at the moment and no screenshot of difficulty either. Video is important to prove the build not only survives boss fights but the actual floors between on Wrangler difficulty. Can you put a video?

I didnt check my notifications so im just seeing your reply, sorry for being late
I made some changes on the build and will update it here once I finish the video (I keep losing my runs due to stucking bugs, even unstuck doesnt work)

Nice run man. And yeah high abyss gets pretty crazy especially in the graphics department. I think I got as low as 10 FPS. Then add the bosses phasing out of bounds and sometimes it sucks.
