In RuneScape, the maximum skill level a player can advance in one skill is level 99 with 13,034,431 experience points. Even though players can have up to 200,000,000 experience in any skill.
If a player is level 99 in all 24 skills, the maximum total levels are 2,376 levels. When level 99 in any skill is reached, there is a different fireworks animation that can be heard by everyone nearby and has bigger and more fireworks.
What makes you special to others when you reach level99 in a skill? Pay-to-play players reaching level 99 in a skill are entitled to wear a Cape of Accomplishment for that particular skill. This cape can be bought from a specific skill master, for 99,000 coins as RS2 money. When operated, this cape allows a player to have a temporary level of 100, and the player performs a unique emote. Furthermore, if the player reaches Level 99 in more than one skill, the player's skill cape becomes trimmed and any more skill capes the player obtains will also become trimmed (along with the newly received cape, of course).
Cooking and Fletching give fairly quick training, with anywhere from a cost of 1-8 million coins as RS money to a profit of up to or exceeding 3 million depending how they are trained. Thieving is another little-known skill that gives quick experience. Getting level 1-45 Thieving can take less than a week. It will cost more Runescape moneyif players want faster experience in Cooking and Fletching. Strength is by far the most trained, resulting in the highest number of 99s. Level 45-99 Thieving can be done in 2-4 weeks, depending on how long someone plays each day. Gaining 99 levels is not easy no matter which skill, and thus classified as a major achievement. This is why wearing the Cape of Accomplishment is something to be proud of.
The skills that are considered cheaper or profitable in RuneScape gold making to gain level 99 are Mining, Woodcutting, Fishing, Hunter and Runecrafting. A player can do this with a minimal amount of RuneScape money or RS gold or while making profit. However, RuneScape leveling up these skills can be time consuming.
In RuneScape Classic, the maximum total level was 1,782; the addition of Runecrafting (1881), Slayer (1980), Farming (2079), Construction (2178), Hunter (2277), and the newest skill, Summoning, brought the maximum total levels to 2,376.
