even if the arach trade is legit, where did the fg for ber come from? jah is half the battle
A collection of items sometimes is enough. Tals ammy + a few eth bases + mid runes + skillers or whatever. People do these trades. Same if he was to sell off those items for ist each and upgraded the runes to ists. It really isn't hard to farm the VALUE of a singular high rune, the toughest part would be finding that trade.
I'm not denying that he probably used a generous fan, but I did a no-JSP run one ladder, it is far slower and moronic, but I for sure had an Enigma in similar play time. And that wasn't even with me being setup for it like he is.
