I predict it does not go well. Where is life tap? You don't really want to use a wand with charges vs ubers it's too easy to let it drop and not be able to re cast. Life tap wand is ok vs d clone. You also need open wounds, usually dracul gloves or gore boots.
Point in salvation to use vs meph unless you have literally 300 light res for meph.
Use 4 or more antidotes before you fight lillith, and another 4 antidotes + 4 thawing pots before meph. Those add to your res, for 30 seconds each.
I don't see how hustle would help. If it's for fanat on a merc, merc will probably die.
You need life tap and open wounds or prevent monster heal at minimum. Please start with dClone first, since that one you have good chance to beat even using a ton of pots to keep merc alive, even if you return to town. Lilith and uber trist are much harder and less forgiving. Good luck.
Edit: and repair black flail immediately before going to trist!
++ make treachery to pre buff fade before all uber and mini uber fights. My first ubers i re did fade 3 times only to clear Matron's Den.
