Click to open it and then scroll down to find the cfggameplay.json file in that folder.
You will need to stop your server before you can edit it.

Open the file and search for sprintStaminaModifier lines there. You can download it and open it in your favourite text editor such as Notepad++
Here you need to replace these lines with the following:
{
“sprintStaminaModifierErc”: 0.01,
“sprintStaminaModifierCro”: 0.01,
“staminaWeightLimitThreshold”: 6000.0,
“staminaMax”: 100.0,
“staminaKgToStaminaPercentPenalty”: 0.01,
“staminaMinCap”: 0.01
}
Now your character will have infinite endurance and won’t faint anymore after running so you don’t have to worry about the stamina levels ever.
That’s it, now go ahead and make these changes to enjoy infinite stamina!
