WHERE & HOW TO FARM Where to farm Episode 17 → Extreme Mode → H17-3.
H17-3 is the third listed Episode 17 Extreme operation. Use the in-game preview to understand its enemies and condition, rehearse if needed, and claim the completion rewards from the result screen. Its purpose here is challenge progression, not an unsupported repeatable material route.
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. 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. Farming tips 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.
