I can do the abyss with warlock. It takes a few tries. The trick is to jump from the tip but you have to look up as you jump. I don't know if it's just looking over the ledge or totally up. I just run, when I'm about to hit the tip I look up and double tap x. Most of the time I end up just seeing the ledge scratch my skin and then assume the doggy style position. Every now and then I'll make it up and wonder why I didn't buy heavy ammo. But once, I had everything and it was glorious! Ogre still killed me but that's what sunsinger is for. I killed it after five or six ghallajhorn rockets.
Just avoid the knight at all costs. He seems a little more angry. Fusion grenades work best. He starts to charge you throw, he ducks you little girl run for your life.
I used sunsinger, fully agility, that means no two grenades. I used the setting just above the two grenades, the one where you can hang in the air if you aim, it seems to give extra agility. Fo weapons I had mida multitool, plug one and both had + agility, just in case it did something.
When I made the ledge I immediately switched to ice breaker but then decided that won't do anything except tickle the big baddies. Switched to ghallajhorn and used the ammo synth. Don't use ice breaker, you'll be there all day trying to kill the knight. You don't damage the ogre. It will take 8+ crits to kill the ogre. But you'll run out of ammo before you kill it and it will kill you.
If you have a 32 Titan it is much easier than that.
