WHERE & HOW TO FARM
Build a mana reserve from Survival loot
Survival on a campaign map you have completed, followed by the Tavern forge.
Before you go
- Complete the map’s Campaign mission to unlock Survival for it.
- Have a defense setup that can clear several waves reliably.
- Have inventory space to compare drops and identify items worth keeping.
- Set a mana goal, such as funding defenses or a planned weapon upgrade.
Farming steps
- Choose a completed map and the highest difficulty your current defenses can sustain consistently.
- Start Survival and build defenses around the map’s enemy lanes and crystal approaches.
- Clear a wave, then review equipment drops during the between-wave phase.
- Keep pieces that improve an active hero or build; mark or reserve them so they are not sold accidentally.
- Continue through additional waves while the defenses remain stable, collecting useful drops as they appear.
- Return to the Tavern and sell only the equipment you have confirmed is surplus.
- Check your mana balance against the goal you set, then spend it on the planned defense or weapon improvement.
- Compare an item with gear on every hero who might use it before treating it as surplus.
- Use a lower difficulty if repeated losses interrupt the wave-to-wave collection loop.
Repeat, collect and use
Repeat Survival runs and sell confirmed surplus after each run. Wave loot and sale proceeds vary; this is repeatable, with no fixed mana yield.
Common mistakes
- Selling quickly between waves: pause to compare drops and reserve useful items first.
- Continuing after defenses become unreliable: leave with collected loot and choose a more stable setup next run.
- Spending the reserve on an unplanned upgrade: keep the mana for the defense or weapon goal you chose.
When to stop or switch
Stop when the reserve covers your planned purchase or when the current run becomes unreliable; switch maps or lower difficulty if you still need more mana.
