Yay! Completed last challenge 9. Rat Monarch without Binlor,
Did it with Mystera, I did have Soul Orb from my "Dream Set" but other items I used weren't from it (Platemail and Agnostic's Collar):

Luck definitely plays a big part, like I had a previous run where I managed to reach floor 6 (didn't find Dracul by then, and also no Binlor level which is useful especially if you get it early like floor 2). For this run, I had Binlor level in floor 2 but wasn't able to save much blackspace (nothing left by the time I got to H) due to getting Dancing Blade and Fireball Retaliate (I was lucky since I had kept Endiswal and was at least able to put my mana to good use). Finding Dracul early (floor 4) basically meant a very good chance for victory,
This proves that it is doable without using Binlor though I still find using Binlor less luck-prone (more combination of items that can lead to victory).
Another thing is that it's entirely possible to win without 2 levels of Lifesteal so you can actually swap in Vampiric Blade for Draining Blade and get to make use of resists much earlier. This means Burn Salve can be replaced by another potion probably Dodge or Reflex potion. It may also be possible to prep Apothecary rather than Quest Items (potions are "cheaper" than most items and being able to get 2 more shop refills plus 2 more potions can help too).
