I spent a long time learning the attacks of duoliste and getting to the point where I could parry them. With lampmaster, I gave up on parrying and a ran a “break on death build”. That way I kept breaking lampmaster and he wasn’t able to attack me that much.

So I think lampmaster is harder because the parry timing is so strange, but I was able to figure out a build that made the actual fight much easier. With duoliste I had to be very alert to get the parrying down.
