i can easily kill uber izual & duriel but lillith easily destoys me. my resists are 72/72/75/75

does she kill you quickly or are you not able to kill her?

She kills me quickly

What’s your workout program look like?
Are you getting enough proteins?
Are your stress levels high and are you not sleeping enough?
What kind of music or mindset are you in while battling her?
These are the questions you should answer correct these and you should be able to defeat her goodluck

then you might just have to switch to another style. hammerdin has one crucial weakness which is sustain. physical builds allow for life tap, so maybe go for grief/cb/ow/ias gear with some lifetap and smite her. use one antidote after the fight so her minions dont kill you

Just use 1 pt smite and dracs with some cb and you're fine.

Enigma.

Cast Hammer then tele
Cast Hammer then tele
Cast Hammer then tele
Cast Hammer then tele
Cast Hammer then tele
Cast Hammer then tele
Cast Hammer then tele
etc...

She will never touch you if you use tele to dodge her attacks.

Enjoy!

Why would resists matter against her melee attacks
