Experience

rsw:Experienceosrsw:Experience

The amount of experience required to level up increases dramatically

Killing monsters and fulfilling certain tasks will grant players experience (also known as xp, exp, or experience points) that they can accumulate to increase levels in a skills. To reach level 99 in a skill, players need 13,034,431 exp, and reach only half that amount between level 91 and 92. To reach level 99 in all 18 skills, players need to accumulate a total of 234,619,758 exp.

Hits

The Hits skill is a special case, since all accounts start with level 10 and 1000 experience. This isn't enough for level 10 in other skills, however, and when RuneScape 2 was released, accounts that had not reached 1154 Hits XP had their Hitpoints level in RuneScape 2 set to the correct value for 1000 XP - level 9.

Maximum experience in a single skill

Unlike RuneScape 2, RuneScape Classic does not have an experience cap at 200 million, instead, it is not possible to exceed 536,870,911 (${\frac {2^{31}-1}{4}}$) experience in a single skill because of data type limits.

Passing the maximum XP results in integer overflow, and the displayed value will wrap around to a very large negative number. It is possible to continue gaining experience afterwards. Going from negative to positive experience does not cause the level to reset to level 1. Only one person is currently known to have negative experience (in Thieving).

The reason for the limit being a quarter of the usual maximum for 32-bit singed integers (2,147,483,647) is precision. The number is divided by four before being displayed in order to allow for a limit set of possible experience values below 0 (0.25, 0.5, and 0.75). For example, killing a chicken gives 6.5 Hits XP, but the number beyond the decimal point is not displayed on screen.

Experience table

The following table shows the relationship between skill level, the experience required for that level, and the experience difference from the previous level:
