=== Active combat penalty ===
The experience awarded for fighting a mob of a certain level below the player's combat level can be estimated with the following formula. This is reflected when looking at monster information cards.
When initiating active combat, the "Displayed penalty" on the battle initiation interface in-game, as noted in the table below, is not always entirely accurate. The "Actual penalty" column in the table below refers to an estimate of a more precise penalty value calculated using actual numbers. Keep in mind that as monsters have differing base experience, some mathematical rounding errors may occur. The greater the base experience of the mob used to calculate actual penalty, the more accurate the penalty will be.
The maximum penalty applied to active combat experience in this way appears to asymptotically approach '''99.9%'''. Currently the closest point at which this is achieved occurs when comparing a level 500 Watchperson with a level 39 Eyeless Zombie, for which the player will obtain '''1xp''' out of the monster's 758 base experience, resulting in a 100% - 1/758 = '''99.87%''' penalty, correct to two decimal places. As a level 500 Watchperson will obtain 2xp from the next highest levelled monster (a level 48 Snarling Spectral Stalker), this places the current known easy battle penalty soft cap between a level difference of '''+453''' to '''+461''', subject to further testing.
<math>Current XP = BaseXP \times 0.5^{\frac{C - M - 10}{50}}</math> rounded down to the nearest integer.
As the player will always receive 1xp minimum for defeating a monster, it is impossible to visualise any further penalty increases in-game beyond a level difference of '''+461''', even if lower level monster data suggests this to be the case. Given current data, the base experience of any monster below level 39, from which a level 500 Watchperson would still obtain 1xp, would result in a higher final percentage and therefore negatively impact the precision of the calculated penalty. For example, a level 500 fighting a level 1 monster would still only gain 1xp, but because the monster's base xp is only 205, this results in a less precise calculation as 1/205 is bigger than 1/758.

Currently the greatest observable penalty ingame occurs when comparing a level 500 Watchperson with a level 39 Eyeless Zombie, for which the player will obtain '''1xp''' out of the monster's 758 base experience, resulting in a '''99.87%''' penalty correct to two decimal places.
