Why External Detonation Matters Now
External Detonation is not only a significant test of your puzzle-solving skills but also a primary source of high-value chests and event-limited currency. With multiple mechanical layers, missing a single switch can lock you out of key rewards until the next stage reset.
Completing all puzzles efficiently can have a direct impact on your advancement and shop redemptions. Given Arknights: Endfield’s resource-centric design, optimal routing through this stage makes a tangible difference for both F2P and low-spend players vying for milestone event goals.
Step-by-Step: Clearing External Detonation & All Chest Locations
Before You Start:
– Confirm access to the Delver of the Cryptic event hub
– Bring operators/characters with reliable burst skills for timed puzzles
– Clear prior event stages if required (see Industrial Labyrinth guide on EarlyGG)
1. Entryway Switch
- The very first switch is in open view; perform a basic attack to open the initial door.
2. Moving Platform Puzzle
- Mechanic: Central moving platform with a timed switch
- Solution:
- Attack the central switch precisely as the platform aligns, pausing its path
- Before advancing, head toward the platform’s opposite end to access the first chest (often missed)
3. Double Switch Gate
- Mechanic: Dual switches adjacent to a gate
- Solution:
- Strike both switches
- Alternatively, use an explosive barrel placed nearby to trigger both simultaneously for efficiency
4. Four-Switch Central Gate
- Mechanic: Large locked gate requiring four switches
- Solution:
- Locate two switches to the left and two to the right
- A weight-sensitive platform in the center enables interaction with explosive barrels on top — use them to trigger distant switches
- Hit all four to open pathway to the next area
5. Triple Switch with Moving Targets
- Mechanic: One static and two mobile switches; explosive throwing required
- Solution:
- Stand in line with the moving switches
- Time your explosive throws so barrels hit moving targets as they align
- Adjust your character’s position for the hidden center switch, which can be occluded
6. Secret Chest Gate
- Look for a concealed gate on the right; hit the switch to reveal and open the second chest
7. Final Area – Platform Combo
- Puzzle: Chest at center surrounded by three distinct platforms (one moves)
- Solution:
- Hit the switch next to start the platform moving, then stop it at the midpoint
- Wait for the other platform to come close, then cross using both
- Collect the final chest
- Use remaining explosive barrels and switches to realign platforms for the final jump

Materials & Daily Cadence Table
| Chest # | Area | Prerequisite | Reward Type |
|---|---|---|---|
| 1 | Moving platform | Stop platform, backtrack | Event currency/materials |
| 2 | Secret side gate | Hit hidden switch | Upgrade/item drops |
| 3 | Center zone | Cross with aligned platforms | High-value event item |
Reset times for daily attempts: Not stated in official materials — check event calendar tab for server-specific resets (usually UTC+0).
Optimal Teams & Loadouts
- Tier 1: Operators/characters with ranged or area attacks (facilitates switch/trap clearing)
- Tier 2: Multi-hit or rapid skill cooldowns (reduces wait on timed puzzles)
- Budget/F2P: Prioritize free event operators with skill deployment abilities
Team Tips:
– Assign one ranged and one melee for mixed platform/switch accessibility
– Avoid slow, clunky characters if possible; timing is critical
Troubleshooting & Common Pitfalls
- Missed chests: Check for off-path switches—most skipped chests hide behind these
- Platform out-of-sync: Reset puzzle section by leaving & re-entering room
- Explosive barrels missed: Wait for cooldown and reattempt; barrels respawn after short delay
- Time pressure: Pre-aim attack reticles before the platform/switch aligns
