I figured that hey, I'm level 50 now. That 30 something level quest to go jack Ivar shouldn't be too bad.
OK, well.. not the case. I went around killing off wights mostly one-offs or in pairs. more than 2 is very risky.
There's a gate to Ivar... closed. Come to find out, you must defeat Blogkrit, an 11K badass that seemed mostly immune to my Riddle and Subtle Strike. I hardly did any damage either.
In the third attempt, I got him down to 4K, but he got me before I could HiPS or play dead.
Next time I gotta suck it up and wait for help/LFF.
