Relics are picked during a run, one per dungeon level, and last only
for that run — they are not gear. Which pool you are offered depends on what you have
equipped, so they are listed by the ability that unlocks them. Locked tiers still appear:
a lower-level ability shows the same relics with more of them greyed out in game.
Measured from play rather than published anywhere, so treat it as a
community record: a patch can change any of it, and what the game shows you in a run is
always the authority.
