Luck is a mechanic that determines the chance for receiving certain rare or special drops and rewards from various sources. Luck was significantly reworked on 27 March 2017 in an update to categorise affected drops and rewards into 4 tiers of luck, each corresponding to one or more luck enhancing items.

Prior to the luck rework of 27 March 2017, luck was only improved by the ring of wealth, Collector's insignia, leprechaun hat, and luck potion, all of which:

  • Slightly improved the chance to receive unique drops from monsters (but only some bosses)
  • Improved the rare drop table access chance and clue scroll drop chance
  • Increased the chance of finding gems while mining

All of these items’ effects were identical (charging the insignia doubled its effect) and did not stack.

The 2017 update added tiers to luck, and rings to fill those tiers with the existing ring of wealth being moved into tier 2.

Prior to 12 June 2017, only tier 4 luck inherited the effects of lower tiers of luck. The update that day changed this so that all tiers inherit lower tiers of luck.
