1 difference could also be that having such high damage (14k) also means less safety in character and less comfortable running overall, and that could have ruined performance a bit. There is no way around sadly - for having such high damage you really need to sacrifice safety. From what I can tell, there is really no point to go over 120006 Blizzard damage which is maximum possible (if player also has +2 skills BKWB rings) by also having strong resistances, but neglecting MF. But, assuming all player has are 1.13 rings, then upper limit would be at 11220 damage (using +3 cold skills 10 fcr amulet, but I would argue 2/10+adds might be better for safety). As I would still argue that MF is not irrelevant, but it is better to at a very least use War Travelers + Gheed + perhaps few small charms to reach 100+ and saying 2/10 amulet is superior due to what it can offer, that would in my book put maximized damage at values: 10434 for double SoJ build or 11220 for beta BKWB build. This is for 105 fcr which is better to aim for than 63, but 63, even if slightly inferior, is still fine. This also assumes 4x4 inventory space because lower than that actually slows you down, especially using the cube. Cube is for players who pick much, but they don't have a chance to challenge faster players anyway. I even use 5x4 inventory because you can run even longer before needing to visit the stash, but 4x4 is fine. All numbers presented assume perfect Fathom and perfect Nightwing's too.
