They functioned in roughly the same way as Zamorakian emblems and similar currencies: * They could be earned from almost any skilling action, or combat, every 3 minutes, or from completing daily challenges. * They could be stored in the currency pouch. * Up to 1,000 could be earned per day, for a total of 14,000 over the whole May 2017 event. * The amount earned per day could be increased by 1,000 using a 1-day or 5-day limit extender * For the October 2017 event, there is no daily limit. * 10,000 tokens were required to earn all of the rewards, though they could be directly turned into event mystery boxes (250 each) or big event mystery boxes (500 each).
