# Experience

Experience, commonly abbreviated as EXP or XP, is a measure of progress in a certain skill. It is obtained by performing tasks related to that skill. Experience can also be gained through other means, such as quests, the Book of Knowledge from the Surprise Exam random event, a lamp from the genie random event, certain mini-games, and lamps for completing parts of the Achievement Diary.

After gaining a certain amount of experience, players will advance to the next level in that skill, which can result in new abilities, and the chance to try more quests. The amount of experience needed for the next level is approximately 10% more than the last level. For example, 83 experience is required for advancement to level 2, while 91 experience is required for advancement to level 3. This expands rapidly to a total 13,034,431 experience needed for level 99. Level 85 requires nearly one quarter of the experience needed for level 99 and level 92 is nearly the exact halfway mark, requiring 6,517,253 experience.

Experience is stored as a 32-bit integer with one decimal point,[1] although the game does not display decimal values; for example, if a player receives two experience drops of 2.5, the first is shown as 2 and the second as 3 (or vice versa depending on their existing experience points). Experience values that would have multiple decimal points, such as through multiplication with experience-boosting sets, are rounded down to one decimal. The maximum experience that can be obtained in one skill is 200,000,000. The skill can still be trained afterwards, but no experience will be received.

## Experience table

### Levels 1-99

The experience difference between level ${\textstyle L-1}$ and level ${\textstyle L}$ is ${\textstyle {\frac {1}{4}}\left\lfloor L-1+300\left(2^{\frac {L-1}{7}}\right)\right\rfloor }$. The tables below show this experience difference for each level and also the cumulative experience from level 1 to level ${\textstyle L}$.

## Formula

The formula needed to calculate the amount of experience needed to reach level L is:

${\displaystyle {\mathit {Experience}}=\left\lfloor {{\frac {1}{4}}\sum _{\ell =1}^{L-1}}\left\lfloor {\ell +300\cdot 2^{\ell /7}}\right\rfloor \right\rfloor }$

If the floor functions are ignored, the resulting summation can be found in closed form to be:

${\displaystyle {\mathit {Experience}}\approx {\frac {1}{8}}\left({L}^{2}-L+600\,{\frac {{2}^{L/7}-2^{1/7}}{{2}^{1/7}-1}}\right)}$

The approximation is very accurate, always within 100 experience but usually less than around 10 experience.

## Graphs

The experience required for each level can be graphed. Graphing the experience required on a linear scale shows that the experience required is essentially exponential.

Graphing the same data on a logarithmic scale shows that the function deviates from being exponential before around level 10.
