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 toggle this option 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).
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 run energy for every 2 covered squares (for each game tick of 0.6 seconds). Having negative weight is the same as having 0kg of weight for purposes of run energy. A Stamina potion or Stamina mix reduces the rate at which run energy is used.
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.
|Agility Level||Seconds per 1% Energy|
The amount of time required to recharge energy from 0 to 100% varies as a function of agility level. You regain 8 + (Agility Level / 6) energy units every 0.6 seconds (one game tick). 10,000 energy units is 100% run energy. The natural recovery rate is 1% per 7.5 seconds for free players or players with level 1 Agility. There is no difference when walking or standing still. This recovery rate is doubled at level 50 agility. At level 99, the rate of recovery is 3x faster.
Grace's Graceful Clothing Edit
Wearing a full set of Grace's Graceful Clothing will increase one's energy recharge rate by an additional 30%.
Energy can be recovered more quickly by using a number of items:
|White tree fruit||5-10%|
|Energy potion (f2p)||10% (per dose)|
|Stamina potion||20% (per dose) + reduces run energy depletion by 70% for 2 minutes|
|Purple sweets||10% (per piece)|
|Summer pie||10% (per bite) + 5 Agility boost|
|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% (three times daily)|
|Explorer's ring 3||50% (four times daily)|
|Explorer's ring 4||100% (three times daily)|
- Dying, exiting a duel in the Duel Arena, and entering and leaving the free-for-all Clan Wars portal restores the player's energy to 100% (as well hitpoints and all other reduced stats).
