Medium meteorite is an item that can be won through Treasure Hunter as part of the Meteor Storm promotion added on 21 January 2016 or the 2016 Christmas Advent Calendar. When used it will give 33% more experience in a chosen skill than a medium prismatic lamp, or 100% more if the skill chosen is one of the player's five lowest skills. If the player's Dungeoneering, Invention, and/or Slayer level is less than 120 those will count as lower than any level 99 skill.
- Before an update on 12 January 2017 the experience boosts were 25% and 75%.
- On the day of release the lowest seven skills got the 75% boost, presumably due to a bug.
