WHERE & HOW TO FARM
Where to farm
Cairos Dungeon > Giants Keep; choose the highest stable tier available to your team.
Farm Giants Keep when the rune sets shown in its reward panel fit monsters you are building. The useful target is the highest difficulty your team can clear consistently, since failed or unreliable runs interrupt collection. Review each rune after a run: keep pieces that suit a current build, and sell pieces that do not meet your account’s standards. This turns energy into a steady stream of gear and mana rather than an accumulating pile of unreviewed drops.
Have a team that completes the selected tier reliably.
Decide which rune sets or build slots you are trying to improve.
Open Giants Keep and check its current reward information to confirm the available rune sets.
Select the highest tier your team can finish repeatedly without frequent failures.
Start a run and let the team complete the boss encounter.
Collect the reward and inspect each rune’s set, slot, main stat, and substats.
Keep pieces that advance a current build; sell pieces that do not meet your filter.
Use mana and other displayed rewards to support rune upgrades and further farming.
Farming tips
Farm for a named build need; a higher tier is useful only if it remains dependable.
Review storage regularly so potentially useful pieces are not buried among low-value drops.
Repeat, collect and use
Repeat while Giants Keep sets address a real equipment need. This is an ongoing dungeon farm, not a one-time reward.
Common mistakes
Switching tiers for a small improvement in drop quality despite frequent failures; return to the highest tier you can clear steadily.
Keeping every rune; apply a consistent filter and sell pieces with no likely use.
Treating all rune sets as interchangeable; prioritize the sets and slots needed for specific builds.
When to stop or switch
Pause Giants Keep when your next target needs another dungeon’s rune sets, or when saved energy is better spent on a higher-priority progression activity.
