Going in: I warded myself from spellbook with Keen Edge on my DPS weapon, IMA, Shield, Mirror Image, Heroism, PfE. Mid-way, I had to recast Shield due to cl 10 caster.
I've stumbled on 2 mystics at once while rounding a corner, making use of HiPS to dodge or mantles to nullify Isaac's + burst of glacial wrath impossible.
Gross income, counting only the chests I looted WITHOUT the boss chests, selling everything to Thunderhammer:
3824 gold
Net income, accounting for consumables
NEGATIVE 1590
Gross income, including mob drops but without boss fight
4196
net income, accounting for consumables
NEGATIVE -77.6
Gross income, including boss chests, but not mob drops
3824
Net income, accounting for consumables
NEGATIVE 1650
Gross income, chests and mob drops - including the king's own drops
10 752
Net income, accounting for consumables
5278
Basically, the only thing that made this run profitable was the ability to solo the FGK. Had I not fought him, I'd have walked away with a loss of 78 gold pieces (essentially, breaking even with marginal loss).
I don't think we should expect level 30s to be able to solo bosses to make profits if they mostly play during dead hours.
Even with soloing the FGK, all the profit came from his personal gold, not the chests.
