Mastery Tokens

Mastery tokens give 0.1% of the maximum mastery pool exp to mastery pool of the corresponding skill when they are claimed. Mastery Tokens are earned randomly while skilling in a non-combat skill. The drop chance for mastery tokens = 1 in (20000 / milestones unlocked for that skill). Each thing you unlock by leveling the skill counts as a milestone e.g. smithing steel platelegs is unlocked at level 40 and counts as one milestone, additionally reaching level 99 in a skill counts as one milestone). Wearing Clue Chaser's Insignia increases the drop chance by changing it to 1 in ((20000 / milestones unlocked) * 0.9).
