First, max fire + all resist at level 82 is 93 (hitting the 80 cap) with this gear (all of which is available right now without DC spend):
- King Blade/Staff/Dirk of Clubs/Diamonds/Hearts/Spades +15
- The Barons Fearless Helm +15
- Sundragon Pendant +12
- Puzzling Cards +17
- Senior Soulthread Loop/VoidWoven Belt +13
- Jeweled Seal Ring of the Wall/Mechanical Ring VI/Powerlight Ring/Rose General's Ring +10
- Mirror Eye Trinket +10
- Legion Bracer
You don't need all of the gear listed here, but it's pretty easy to reach the 80 resist cap for Fire even at level 82.
While DoomKnight is a fine choice (burst her down in a single boosted, scouted inner darkness and survive at 1 hp using Dragon Scales), it's probably easier to use a class like Necromancer (whose no hitcheck DoTs ignore both her BPD Shield and her damage reflect), Baltael Soulweaver (which can burst down Lust in a single go consistently) or Kathool Adept (same, except you also kill the desirelings).
EDIT: This probably belongs in the battle strategy thread or the Q&A forums.
