I load up about 6 players in a game (for /players 6 and easy muling). My lancer then runs council and clears river of flame and flayer jungle. Selling same stuff as you obviously (making sure to repair for extra $).
I then gamble in a norm game with my level 1 Eunuch-Block din, who has biggins, tarn, hand of broc, treads, hotspur, gorefoot, greyform, blinkbats and nightsmoke. My barb has nagel and manald in his stash. I gamble for leather gloves, boots, heavy boots, caps, skull caps, quilted armour, leather armour, rings and belts.
Getting a good rare sash would just annoy me if I gambled one imo. I can't use a belt with so few potion slots.
I did what I think was my 40th level 29 imbue of a martel the other day. Still haven't gotten anything better than a 260 max damage marty with no other fun mods. Not much better than a good bonesnap
But my ring collection is getting pretty nasty now.
Show pic of your lance? And I know you're going for mass leach, but have you tried iceblink out? It feels so good having every monster explode into icy shards with every WW.
