Medium space dust detail

Medium space dust is a promotional item on Treasure Hunter as part of the Meteor Storm promotion added on 21 January 2016. When used, it will give 33% more bonus experience in a chosen skill than a medium fallen star, or 100% more if the skill is one of your five lowest levelled skills. When you have multiple space dust in your inventory, you are given a selection on which one(s) to use. If the player's Dungeoneering, Invention, and/or Slayer level is less than 120 those will count as lower than any level 99 skill.

  • On the day of release the lowest seven skills got the 75% boost, due, presumably to a bug.
