=== Easy battle penalty ===
In [[combat]] and activities which involve combat, such as [[detective|Crime Dens]], defeating a monster that is '''11 or more''' levels below the player's combat level will incur an experience penalty, known as the '''easy battle penalty,''' on the experience earned from completing the activity. This penalty increases with increasing level difference.

Although the game has a display for this during combat initiation, this indicator is not always accurate. The experience awarded for fighting a monster of a certain level below the player's combat level can be more accurately estimated with the following formula. This is also reflected when looking at monster information cards, and is calculated using the player's '''current''' combat profession compared to the monster's combat level, even if the card of the monster being viewed is from another episode.


<math>Current XP = BaseXP \times 0.5^{\frac{C - M - 10}{50}}</math> rounded down to the nearest integer.


where <math>C-M-10 \geq 0</math>

From this we can deduce that the XP penalty itself is given by the following


<math>Penalty% = 100 \times (1 - 0.5^{\frac{C - M - 10}{50}})</math>

where <math>C-M-10 \geq 0</math>











The theoretical maximum penalty, applied when a level 500 player fights a level 0 monster, according to this formula, is '''99.89%'''. However, due to the low base experience (205) of a level 0 monster, this value (0.23) is rounded up to 1xp, which is the minimum xp a player can earn after defeating a monster. This decreases the actual penalty to '''99.5%''', despite the actual penalty being theoretically much higher.

Currently the smallest observable penalty ingame occurs at a combat level difference of +11, giving a penalty of 1.38% (displayed as 2% in-game), while the greatest observable penalty, currently still subject to more testing, occurs when comparing a level 500 Watchperson with a level 39 Eyeless Zombie, at a level difference of +461, for which the player will obtain '''1xp''' (rounded down from 1.46) out of the monster's 758 base experience, resulting in a '''99.87%''' penalty correct to two decimal places (displayed as 99% in-game).
