WHERE & HOW TO FARM
Farm boss keys from end bosses
End-boss encounters across the campaign, including Telkines, Typhon, Hades and Surtr on eligible difficulties.
Before you go
- Select the target Chaos Dungeon and difficulty before farming.
- Reach at least one end boss eligible to drop that key set.
- Have storage space for key pieces; duplicate copies may be held in stash.
- Bring a reliable build for repeated boss clears.
Farming steps
- Check the key name and number for the dungeon gate you intend to open.
- Choose an eligible boss and difficulty: Greece keys are available across difficulties; Egypt keys require Epic or Legendary; Hades keys require Legendary.
- Travel to the nearest activated fountain and follow the campaign route to the boss.
- Defeat the boss, collect its loot and check your inventory for the needed key piece.
- Move collected keys to stash so they remain organized and are ready for the gate.
- Repeat eligible boss clears until you have one of each of the three numbered pieces.
- Take the set to its matching gate only when ready to spend it.
- Electrum orbs are another listed key source where available, but those purchases use Electrum rather than gold.
- Key pieces are not guaranteed per boss kill, so choose a boss route you can clear efficiently.
Repeat, collect and use
Repeatable while the eligible boss encounter can be reset. Keys are randomized drops; opening a gate consumes a set for that difficulty, so farming is needed again for another tier.
Common mistakes
- Farming the wrong difficulty band: match the key set’s eligibility before choosing a boss.
- Using a partial or mismatched key set: collect the three numbered pieces for the same dungeon.
- Carrying keys into an unintended gate: store them until you are ready to commit the set.
When to stop or switch
Stop when one complete set for the chosen gate and tier is in storage; resume only for another difficulty unlock or a new attempt requiring keys.
