Run energy (sometimes called Stamina or Run) is a player's ability to run rather than walk around the landscape, and is measured as a percentage. Players all run at the same rate, unless their energy is at 0%, in which case they cannot run at all. Running is exactly twice as fast as walking. A player running covers 20 squares per 6 seconds, while a player walking covers 10 squares per 6 seconds.
The energy level is displayed in the game's options screen and is displayed by the minimap if the Dataorb option is toggled. These values show how much longer a player can run. Players can switch this option on to run everywhere they go, or they can run to one particular destination by holding down Ctrl when they click to move (see Game controls). Free players and players with Agility level of 1, have a recovery rate of 1 energy every 7.5 seconds. Whereas at level 50 agility, the rate is 1 energy per 4 seconds.
Energy starts at 100% by default, but decreases as the player runs around. The rate at which it goes down increases with the weight of the items they are carrying (i.e. items in the inventory and any items they are wearing or have equipped). You lose (0.67 + (your weight / 100))% run energy for each tile you run through. Having negative weight has no extra effect on energy, it is the same as having 0kg weight.
When the energy reaches 0%, the player can only walk until their energy recovers. The "run" option is also automatically switched off.
Energy gradually recovers (increasing up to a maximum of 100%) any time that the player is not running, i.e. walking or standing still, except at certain times when the player is doing something else, such as crossing an agility obstacle. The rate at which it recovers increases with the player's Agility level, but does not recover at all when the player is logged out of the game. The following formula shows the amount of run energy that will be regained per second:
where is the player's agility level.
You regain 8 + (Agility Level / 6) energy units every 0.6 seconds (one server cycle). 10,000 energy units is 100% run energy. The natural recovery rate at level 1 Agility is 1% per 7.5 seconds. There is no difference when walking or standing still.
Energy can be recovered more quickly by using a number of items:
|Name||Percentage-points of energy recovered|
|White tree fruit||16%|
|Energy potion||10% (per dose)|
|Stamina potion||20% (per dose) + additional effects|
|Purple sweets||10% (per piece)|
|Summer pie||10% (per bite)|
|Super energy potion||20% (per dose)|
|Bandages (only usable in Castle Wars)||30%|
|Explorer's ring 1||50% (twice daily)|
|Explorer's ring 2||50% (thrice daily)|
|Explorer's ring 3||50% (four times daily)|
|Explorer's ring 4||100% (thrice daily)|
- After a duel in the Duel Arena, energy will be restored to 100%. Dying will also fully restore energy (as well all other reduced stats).
- After entering and leaving free-for-all Clan Wars portal, energy and stats would be restored
