RuneScore is a points system used to measure completed achievements. It was added on 29 August 2017 and can be viewed by clicking the Hero icon in the game interface. Most achievements have an assigned value (between 5 and 75) and upon completing the achievement its value is added to the player's RuneScore.
The maximum possible RuneScore is currently 21,081.8, coming from 2,009 achievements, as of 20 November 2019. The in-game interface may show different amounts for both the total of achievements as well as the maximum RuneScore, which is a known issue.
Some achievements that are heavily luck-dependent, such as skill pets, boss pets or boss collection log achievements, do not contribute to a player's RuneScore and have an assigned value of 0. Dynamic achievements that need to be completed again upon the release of new game content also award 0 RuneScore.
On 10 September 2018 RuneScore was added to the HiScores table. A minimum of 500 RuneScore is required to appear on this HiScore. The same update removed all RuneScore awarded from the Completionist Cape, Trimmed Completionist Cape, Master Quest Cape, The world is a safe place, Final Boss, Insane Final Boss, and The Elite achievements.
