Maximum Weight Possible in Dark Souls 2? 

*And Equipment load % too! Ready for some useless data? Here we go!
So essentially weight does nothing except for increase equipment load and equipment load % is what determines roll type breakpoints, roll distance, fall damage and stamina regeneration.
EDIT - My bad, fat roll break point is 70%, not 60%.
Also I noticed when showing how far rolling at 0% equip load is the player performs 3 rolls before running out of stamina, and when suited up it becomes 2 rolls. But it seems % burden is not a factor since you can still wear a piece or 2 of heavy armour to fatroll BUT it still lets you roll 3 times before running out of stamina. Who knows, perhaps the number of armour pieces impacts this?
Oddly enough both Iron Flesh and Promised Walk of Peace BOTH stack together. Expected I guess otherwise Walk of Peace would be beastly in PvP just as a tool to remove buffs!
At max weight and equip load the stamina regeneration isn't impacted much, it more or less caps at 120% too so I left that out or this would be even longer.
So the gear used is in case you missed it;
- Havel's Gauntlets + 11.5
-Havel's Leggings + 11.5
- Minotaur Helm + 9.8
-Iron Clad Armor + 29.8
- Dispellig Ring(+1) +4
-Ring of Giants(+2) + 5
-Gower's Ring of Protection +10
-Ivory Warrior Ring + 5
-Smelter Hammer + 35!!! Do this 6 times!
-Promised Walk of Peace +40% to weight.
As for fall weight here is a link to the formulas and other cool information. Although the calculations seems a bit odd/off when actually testing this on paper. It's suggesting that fall damage is reduced when over 120%?
