Following the advice I got on these forums last week, I have made a lot of progression.
As it stands, I can do up to grift 42 consistently (even the map with the damn bees).
I'm sure I could do up to 45 on a decent map with good density.
I would rather look at improvements I can make in my build and gear before I try pushing higher.

I have a rather mediocre TnT in my stash, but no SS. I've had some people tell me that the hydra build is the way to go regardless of whether I have SS or not, but that just doesn't feel right (although I haven't tried it yet).
I just acquired my aether walker last night before I logged, so I haven't had a chance to really test out some builds that run teleport yet.
Also, I have been gambling on helmet atm because I figured I would start going for the ancient tal rasha pieces while I try to get SS from drops.
