I clear gem with 2-2m buffed (only with epic & bleeding dart) & I do around 25-30mil lines. Although, I am level 208, I use empress soul & it is necessary for me to use a rune of any sorts (except recovery) & speed potion (Green MPE).

should be abt 30m range on gem..anything less i think either gonna be pretty close or not doable

with no buffs to attack speed, you require 26-31m crit lines to comfortably solo the jewel with a bit of time remaining allowing you to be knocked off maybe once.
if you have a mihile link, you can probably do it with a tad less, 23-28m's.

this is all assuming you are lv210 to remove the chance of misses.

I do 10-12m lines on hellux, and can clear about half-way on forehead. Id assuming hitting 20-25ms is minimum to clear it. I'm also using green MPE for faster attk speed. No dsi yet, but eventually.

do-able with 25 mil a line if you don't fall.

Max bruh max all the way.

Break 30m lines

2-2 with around 200% boss

On one of the other threads about this, I heard you need to be able to deal ~280m a second for the jewel. Thats about all I know. Lol
