Crystal Cores come from caught Crystalflies and are used in crafting, including Condensed Resin. Combine a delayed trap payout with manual catches at familiar gathering areas when you need cores sooner.

How to farm
The Crystalfly Trap can be placed at a safe open-world spot, even where Crystalflies are absent. Manual collection areas include Dawn Winery, Clear Pool and Mountain Cavern, and Guyun Stone Forest.
Before you go
- Reach Fontaine Reputation Level 3 to obtain the Crystalfly Trap; Fontaine Reputation requires Chapter IV Act II and the Steambird Interview quest.
- Have 30 eligible ore pieces to operate the trap.
- For manual collection, approach a Crystalfly and interact to catch it; do not attack it.
- Open Fontaine Reputation rewards and claim the Crystalfly Trap at Level 3 if it is not already in your inventory.
- Choose a safe open-world location and place the trap.
- Interact with its orb and supply 30 eligible ore pieces.
- Leave the gadget until its map banner and device state show that collection is ready after seven days.
- Claim the trap’s 15 Crystal Cores.
- For immediate additional cores, travel to Dawn Winery, Clear Pool and Mountain Cavern, or Guyun Stone Forest.
- Approach visible Crystalflies and catch them one at a time; check inventory as you go.
- Use the cores in the crafting menu for Condensed Resin or another recipe that requires them.
Farming tips
- A caught Crystalfly gives one core; attacking it makes it disappear without the core.
- The trap is a slow supplement to manual catching, not an instant substitute for a route.
Repeat, collect and use
The trap produces one 15-core collection after its seven-day cycle and must be supplied again for another cycle. Manual catches return after the reported 24-hour respawn; route yield varies.
Common mistakes
- Attacking a Crystalfly: interact to catch it so it yields a core.
- Expecting the trap immediately: wait for its ready state and seven-day cycle.
- Assuming a route gives a fixed count: visible spawns and account state vary.
When to stop or switch
Stop when your Crystal Core stock covers the next crafting plan; activate the trap again only when you can spare the ore and will use its later payout.
