Based on your description, he must be runing 250 str/dex/cha with Urn of Daryngord/Paramount Shield/dragon blade/solar flair staff/fgm.
I didn't think this strat would be enough sustain through the fight, but I wasn't thinking of of Dragon Blade and potions. Still I'm surprised it only took 5 potions. My guess is that he also succeeded in the 2nd and 3rd end rolls.
This fight is not possible without a healing guest and a 1-time cost mp misc. item. At 250 CHA, the guest should be providing nearly 200 health a turn and the pet about 130ish, making the cha superior to end. Using a sp cost misc. is not a possibility in this case, because you cannot sustain the misc and the guest simultaneously.
However, there are alternatives for misc and guest. For the guest, call twilly can be used for the heal toggle. For the misc., I suggest Magma Leaf, which costs a much more reasonable 840 tokens. Alternatively, you can use Head of Raydius Dragon. Then Darkness resist might be sufficient.
Also, just found out that you can still have infinite resources with non-rares. Astramorph/Elahi Irt of Osiris/Essence Orb is capable of this, though hp recovers very very slowly.
