In the game Oblivion, when your character runs out of stamina (sometimes referred to as fatigue), the character will collapse or fall over. This mechanic is part of the game, especially noticeable if your stamina reaches zero due to running or other actions. Additionally, if you have acquired the gauntlets of the crusader in the Knights of the Nine DLC, your character may be under a curse that causes you to collapse or stumble whenever the stamina is depleted. This curse is lifted once you complete the related questline and receive the Blessing of Talos, which removes the debuff and stops the falling behavior. If you experience falling over repeatedly or getting stuck in certain areas like water after fainting from zero stamina, it could be due to this curse or a related game bug. A workaround for being stuck is to return to the spot where you first fainted and use a paralysis potion to reset your position and recover. In summary:

• Falling over when out of stamina is a built-in mechanic.
• The Knights of the Nine quest and gauntlets curse causes more frequent collapsing.
• Completing the quest and gaining the Blessing of Talos removes this curse.
• If stuck after falling, going back to the spot and using paralysis can help recover and avoid persistent bugs.
