WHERE & HOW TO FARM
Where to farm
Adventure > Rift > Evolution Stone Dungeon; select the Fire element.
Fire Evolution Stones are hero progression materials, so this run is most useful when a Fire unit you plan to keep is short of stones for its next evolution. Element selection makes the Rift a focused farm: spend Coffee on the Fire stage, collect the stones, then apply them to that hero. The stage is repeatable, but the best target is a specific unit and milestone rather than an undirected inventory pile.
Have a Fire hero selected as the intended evolution target.
Keep Coffee available for the runs or sweeps you plan to spend.
Open Adventure and enter Rift.
Choose Evolution Stone Dungeon, not a general resource dungeon.
Select Fire and review the stage and available clear options.
Clear or sweep the highest unlocked stage you can complete reliably.
Collect the Fire stones from the result screen.
Open the target hero’s evolution screen and check its remaining stone requirement.
Apply the stones to that hero when they meet a useful evolution milestone.
Farming tips
Concentrate stones on a core team hero; spreading them across several units delays each upgrade.
Check Dream Evolution Stones and shop exchanges if only a small, specific remainder blocks the target.
Repeat, collect and use
Repeat the Fire stage or sweep with available Coffee while the chosen hero still needs Fire stones. Rift farming is repeatable; the hero’s evolution milestones are finite.
Common mistakes
Running the wrong Rift type: confirm the label says Evolution Stone Dungeon before spending Coffee.
Choosing Fire only because it is available: match the element to the hero you are actually evolving.
Spending stones across many heroes: check the target’s remaining requirement first and focus the planned unit.
When to stop or switch
Stop when the target hero reaches the evolution milestone you planned, or switch to another element or resource dungeon if a different material is now the progression bottleneck.
