WHERE & HOW TO FARM
Episode 17 Extreme Mode H17-3
Episode 17 → Extreme Mode → H17-3.
Before you go
- Episode 17 and Extreme Mode access.
- H17-3 unlocked through earlier Extreme progression.
- Operators capable of addressing the previewed threats.
- Practice Plans for rehearsal when useful.
Farming steps
- Open the Extreme stage list and choose H17-3 once unlocked.
- Read the enemy preview and stage condition carefully.
- Prepare a squad with the damage, blocking, and support needed for those threats.
- Use Practice Plans to test deployment order on the map if you expect difficulty.
- Enter H17-3 and complete the stated clear condition.
- Claim the operation results and verify the clear registered.
- Check the stage list for H17-4 availability.
- Practice deployments before committing when the stage’s timing is unfamiliar.
- Use the condition displayed in your client as the objective; avoid relying on assumptions from another stage.
Repeat, collect and use
First-clear progression is limited to one clear; repeat attempts are for a missing displayed objective or to improve your strategy.
Common mistakes
- Treating all Extreme maps as having the same objective; read H17-3’s condition.
- Skipping rehearsal when a deployment sequence is failing; use a Practice Plan to adjust.
- Repeating after the progression reward is claimed without a clear reason; move to H17-4 if open.
When to stop or switch
Stop on a successful clear if your goal is progression, then switch to H17-4 when the stage list unlocks it.
