Question about progression post 85

Hello everybody,

I'm currently playing on TSC to complete challenges, as my first char ripped at 86 in THC.
I play a voltaxic ranger (windripper when i'll get better damage on gear) with lighting arrow / blast rain.

I find myself a bit stuck since I can get past T8 maps. Everytime I reached it, I always end up dropping some T7, but enventually my pool go back to tier 5.
From T5, I always alch my maps, and after T7 I always use chisels.
Maybe it's just a streak of no luck, but I wanted to make sure if I'm not missing something.

I do have + 24% quantity on gear (crappy gloves/belt unique). Do I need to invest on this ? or maybe the potion + quantity is top priority ? Do I need to change stuff just before killing bosses ?

My old comp requires potato graphics to plays efficiently so grouping with 2+ players may be difficult (especially some kind of SRS / CoC).

By the way, this game is great :)

Thank,
Dercu

Not much you can do besides chiseling/alching and dying as little as possible, item quantity/rarity on your char won't affect map drops.
