Equipment Burden is a gameplay mechanic in Demon's Souls.
It is a measure of the player's mobility with a given set of equipped weapons and armor. Maximum equipment burden is increased by leveling up Endurance and can be increased by 50% by wearing the Ring of Great Strength. Unlike Item Burden, there is no upper limit besides those imposed by level caps for wearing heavy equipment. However, there are penalties for exceeding the maximum equipment burden, as follows:
- When the total weight of equipped weapons and armor is 50% or less of maximum equipment burden, a character can move at full speed and can roll with maximum efficiency.
- When the total weight of equipped weapons and armor is more than 50% but less than 100% of maximum equipment burden, a character runs and sprints moderately slower, and recovery from a roll becomes noticeably slower, greatly reducing its effectiveness.
- When the total weight of equipped weapons and armor equals or exceeds 100% of maximum equipment burden, a character is incapable of moving except by walking, and attempting to roll will stagger the character for about one second.
- Walking in the poison water beyond the Leechmonger Archstone or the plague water beyond the Dirty Colossus Archstone applies a penalty to movement speed according to the next highest equipment burden penalty, i.e. characters below 50% move as if they were between 50% and 100%, characters between 50% and 100% move as if they were over 100%, and characters over 100% are unaffected. Sprinting removes the penalty. Roll speed/ability is unaffected.
- Movement penalties for wearing heavier equipment do not affect the speed of manual actions, such as putting up a shield, attacking with a weapon, or pulling a lever.
- Weapons that are equipped but not currently on a character's person count toward equipment burden; equipped rings and ammunition do not.
