Clear H17-1 as the first listed Episode 17 Extreme challenge and claim its available first-clear rewards.
WHERE & HOW TO FARM
Episode 17 Extreme Mode H17-1
Episode 17 → Extreme Mode → H17-1.
Before you go
- Episode 17 access.
- Extreme Mode available in the Global event interface.
- A squad prepared for the enemy preview and stage condition.
- Practice Plans if you want to test a deployment before a live attempt.
Farming steps
- Open Episode 17’s Extreme Mode list and select H17-1 when available.
- Read the enemy information, map layout, and clear condition.
- Build a squad that covers the threats shown, including appropriate damage and support.
- Use a Practice Plan to test placements if the map is unfamiliar.
- Start H17-1 and adjust deployment to meet the displayed objective.
- Complete the clear and claim the result screen rewards.
- Return to the Extreme list and check whether H17-2 is unlocked.
- Extreme Mode is challenge progression, so plan around the actual stage preview.
- Confirm any reward in the client after clearing rather than assuming a specific item.
Repeat, collect and use
First-clear rewards are one-time; replay only if the interface shows an uncompleted objective or other reason.
Common mistakes
- Entering without checking the stage condition; read it before deployment.
- Treating H17-1 as a normal material farm; use it for challenge completion unless a current reward gives another goal.
- Assuming it unlocks the whole set at once; check the map for the next available stage.
When to stop or switch
Stop after the first clear if you only need progression, or switch to H17-2 when it becomes available.
