• Duration: 2026-06-10 04:00 – 2026-06-15 03:59 (server time)
• Requirements: Unlock Combat Simulation by completing Main Story Chapter 1 "Cat's Lost & Found"

Event Details

To participate, you must have cleared the prerequisite story chapter. Once unlocked, enter Combat Simulation and select any enemy card. Successfully completing the challenge will grant double the usual rewards—this applies to all loot drops, including Agent and W-Engine upgrade materials.

The event is designed to be low-commitment; you can run any available card and still benefit. There is no special currency or battle pass tied to it, making it a pure farming booster.

Daily Buffed Enemy Cards

Each day, five specific enemy cards in Combat Simulation will be buffed. While the exact enemies are not listed in the official materials, the buffs increase the challenge slightly but do not affect the double reward bonus. If you're aiming for efficiency, prioritize these buffed cards for a modest stat advantage (since you'll clear them faster with proper counters). The buffs reset daily at 04:00 server time.

Tip: Plan your runs around the buffed cards to save time, especially if you're farming multiple materials. The buffs rotate, so check the in-game interface daily.

Should You Farm This Event?

Yes – especially if you are a F2P or low-spending player. Double rewards effectively halve the battery cost for the same amount of materials. With only five days, you can significantly pad your material reserves for upcoming Agent releases.

Prioritize high-demand materials such as those for your main DPS or support Agents. Since Combat Simulation covers multiple material types, identify which ones you lack and focus on those enemy cards.

Farming Tips

• Use Auto-Battle: Once you have a strong team, clearing buffed cards on auto-save time.
• Stockpile Ahead: After the event, double rewards will be gone, so farm aggressively during the window.
• Check Daily Reset: Log in after 04:00 server time to see which five cards are buffed for the day.
• Don't Overcap: If you already have a surplus of a certain material, switch to another type to maximize efficiency.

Final Takeaway

The Data Bounty: Combat Simulation event is a straightforward, low-effort farming bonus that rewards active players. Clear your Chapter 1, check your material needs, and run the buffed cards daily for the best return on battery. This is a perfect opportunity to prepare for future content without burning through your reserves.
