The build for this Rogue can be found here: • Pit 125 Run - Rogue Ra...
The only difference for the item used on this run compared to the link above is the amulet used, which placed emphasis on movespeed as this is a requirement to evade majority of this Uber boss' attacks. I must say though that this version of Lilith in Season 4 is a lot easier to kill now compared to the previous seasons as a lot of her attacks no longer means instant death/one shot kill mechanic. This run is much more consistent now than the first one I have in this channel as that one didn't have updated equiments nor optimized skillsets and paragon build.
During her second phase it can be seen that you cannot kill her right away unless and untill she gets to cut off 3 segments of the platform. This seems to be the standard before she can be finally killed so, until then make sure you evade her attacks as they could still do you massive damage when they proc. If you are new to this boss then it might take you couple tries before you finally get her so, you'll have to be patient until you do. After all, being able to kill her, if it's your first time - will give you that coveted resplendent spark as a reward. Subsequent kills though no longer gives you this item - better keep this in mind.
