Endurence?
 

I don't know but maybe Graal: Kingdoms should try and have some sorta endurance. Then people can't just kill kill kill without stoping. Maybe this has been suggested, but if it was it was a old post. Time to revive some dead ideas then.

Anyways I was thinking
You need to sleep sometimes
sitting down works to but it has limitations
For example
Player is low on endurence he is sluggish and slow, and does little damage, while a player whos endurence is at max maybe is slightly faster and quicker than normal, then it just rolls down from there. More weight = faster endurence drops. Attacking causes endurence to drop aswell, walking does aswell but hardly enough to matter (like a point or two)

Anyways to regain lost endurence players would need to rest and or sleep
Sitting down would only slowly regain endurence but only regain by 50% of of the current endurence,
sleeping on the floor would be faster than sitting and only regain by 75% of current endurence
While resting in maybe a tavern room, or somebody elses bed it will regain fast and regain by 100%
Sleeping in your own house would quickly increase endurence and aswell regain it by 100%

Anyways I don't know. <=X

There was endurance long ago. It changed into the food meter. It was called stamina. :D

That's a nice idea but we can also just enhance food. The more weight you carry the faster your food drops. Sleeping/sitting makes your food drop slower. Also, when your food is 0 there should be more bad stuff, like all stats-1, and after half an hour -2, etc.
