Relic odds calculator

Pick where the relic comes from and the effects you want: get the exact chance one relic has them all, and how many relics that takes.

How this works: each relic slot draws one effect from its own table in the regulation, by weight. Effects of the same group (for example every attack-power boost) never share a relic, so later slots draw only from what's left. A source first picks the relic's colour and size, also by weight. The chance is summed exactly over every way the slots can roll; nothing is simulated. 473 of the 519 relic effects can roll.

Reading the result

  • With The Forsaken Hollows installed the game uses each row's DLC weight, which adds Scholar and Undertaker effects to the pools and thins the rest a little.
  • Deep relics also roll curses in their curse slots; the chance here is for the effects you want, whatever curse comes with them.
  • Effects marked with a Nightfarer's name only work for that Nightfarer, but any relic can roll them.
  • Expedition drops roll from the table of the expedition's Nightlord (the game sets it when the expedition starts).

More on the method: the methodology. Every effect's page lists its chance per source: relic effects.
