At a Glance

• Event Duration: 2026-10-14 04:00 – 2026-10-19 03:59 (server time)
• Requirement: Unlock Combat Simulation in Main Story Chapter 1 "Cat's Lost & Found"

Event Overview

During the event, enter Combat Simulation, select any enemy card, and complete the challenge to earn double rewards. This applies to all enemy cards, but each day five specific cards receive additional buffs, making them more challenging but potentially more rewarding. The buffed cards rotate daily at 04:00 server time, so check back regularly to optimize your runs.

Combat Simulation is a core endgame activity where you farm materials like Agent EXP, W-Engine materials, and Drive Discs. Doubling these rewards means you can cut your farming time in half, which is crucial for building multiple characters or preparing for future patches.

Step-by-Step Farming Guide

1. Unlock Combat Simulation – If you haven't already, progress through Main Story Chapter 1 "Cat's Lost & Found" to unlock the mode.
2. Check Daily Buffed Cards – Each day at 04:00 (server time), five enemy cards receive buffs. These are marked in the Combat Simulation menu.
3. Select Your Target – Choose any enemy card, but prioritize buffed cards if you can handle the increased difficulty for potentially better rewards.
4. Assemble Your Team – Use a team that counters the enemy's attributes. For buffed cards, ensure your team is well-invested.
5. Complete the Challenge – Successfully clear the challenge to claim double rewards. You can repeat this for other cards as long as you have battery charge.
6. Repeat Daily – The event lasts five days, so log in daily to maximize double rewards.

Tips for Efficiency

• Prioritize High-Value Cards: Some enemy cards drop materials you need more urgently. Focus on those first.
• Use Battery Wisely: Double rewards apply to the base drops, so spending battery on Combat Simulation during this event is more efficient than usual.
• Coordinate with Daily Reset: The buffed cards reset at 04:00 server time. If you play around that time, you can plan your runs accordingly.

Rewards and Drops

The event doubles the rewards from Combat Simulation, which typically include:

Note: Exact drop rates and quantities are not stated in official materials. The table reflects the doubling effect.

Teams and Synergies

Since Combat Simulation features various enemy types, you'll want flexible teams. Here are some budget-friendly options:

• F2P Team: Anby, Billy, Nicole – A solid starter team that can handle most early Combat Simulation stages.
• Mid-Investment: Ellen, Lycaon, Soukaku – Strong ice synergy for freezing enemies.
• High-Investment: Zhu Yuan, Qingyi, Nicole – Ether and electric combo for rapid clears.

Adjust your team based on the enemy's weaknesses. For buffed cards, consider bringing your best-invested Agents.

Troubleshooting

• Can't Access Combat Simulation? Ensure you've completed Main Story Chapter 1 "Cat's Lost & Found."
• Buffed Cards Too Hard? You can still farm non-buffed cards for double rewards. The buffs only affect specific cards.
• Missed a Day? The event runs for five days; missing a day means fewer double rewards, but you can still farm on remaining days.
• Battery Running Out? Prioritize the cards that drop materials you need most. Consider using Ether Batteries if you have them.

FAQ

Q: Does the event affect pity or drop rates?
A: No, the event only doubles the quantity of rewards. Drop rates for rare items remain unchanged.

Q: Can I farm unlimited times?
A: You can farm as long as you have battery charge. The event doesn't limit the number of runs.

Q: Are the buffed cards the same for everyone?
A: Yes, the five buffed cards are the same across all servers and reset daily at 04:00 server time.

Q: Is this event worth it for F2P players?
A: Absolutely. Double rewards mean less battery spent for the same materials, which is great for F2P progression.

Next Steps

After the event ends, continue farming Combat Simulation as needed, but without the double rewards. Use the materials you've gathered to upgrade your Agents and W-Engines. Keep an eye out for future Data Bounty events, which typically run for a few days each patch.
