The Fissure of Chaos is a challenging Greece endgame dungeon that offers a boss reward and exclusive progression opportunities. Opening it requires one complete set of its three matching keys; each difficulty has its own unlock state and consumes a set for that tier.

WHERE & HOW TO FARM
Where to farm
The Fissure of Chaos in Greece, reached by backtracking from Delphi toward the previous rebirth fountain and continuing north toward the waterfall gate.
Collect the Greece key set from eligible end bosses or Electrum orbs, travel to the Fissure entrance, and decide whether your build is ready before spending the keys. Once inside, the route is linear and dangerous, with a midway choice between an early treasure exit and continuing to the boss. A completed dungeon remains open for that difficulty, but a new run requires the session to be reloaded after finishing or dying.
Obtain one complete set of the three Key to the Fissure of Chaos pieces.
Have access to the intended difficulty; the dungeon’s unlock applies separately by difficulty.
Bring a well-geared build and enough healing for a long run.
Accept that dungeon death loses the experience tomb and ends the attempt.
Store each matching key as it drops so you do not accidentally enter before your build is ready.
Travel to Delphi, backtrack toward the previous fountain, then head north by the waterfall to the gate.
Confirm that the key set matches the Fissure and the difficulty you want to open.
Use the keys at the entrance to unlock that difficulty’s dungeon.
Advance through the fixed route, using levers where gates block progress and avoiding trap lanes.
At the midway crystals, choose the early exit for a smaller treasure stop or continue toward the boss.
Defeat the boss for its reward, then leave through the exit route; reload the character session before another attempt.
Farming tips
The green crystal continues the dungeon; the red crystal chooses the early treasure exit.
Keys are consumed when opening a difficulty tier, but that tier’s gate remains open afterward.
Repeat, collect and use
The dungeon can be entered again after completing its one-time unlock for that difficulty, subject to the session reset rule. Another difficulty has its own key cost and unlock.
Common mistakes
Spending keys before the build is ready: store the full set until you can handle the route.
Assuming the Normal unlock opens Epic or Legendary: plan a separate key set for each tier.
Expecting to teleport out or recover a death tomb inside: finish the route or accept the failed run.
When to stop or switch
Stop after claiming the boss reward or early chest; switch to key farming only when you intend to unlock another difficulty or retry after a reset.
