Equip Burden

From Wikidsouls

Equip burden refers to the weight of the weapons and armor you have equipped, which includes both primary and secondary weapons for each hand. If your Equip burden is less than half of your max, you can move at full speed, and can roll quickly and often. At more than half, your move speed is reduced, and rolls become slower and drain more stamina. If you pass your maximum equip weight, your character will no longer be able to run. Equip burden can be increased by leveling the Endurance stat.
