Is Data Bounty Combat Simulation Worth It?

Recommended for Most Players

We recommend farming while the Data Bounty: Combat Simulation is active because this will double the amount of drops for Dennies, Skill Chips, and Certification Seal you can receive for character promotion!

If you plan on building an entire team, it's best to do it while this event is active to save up on Battery Charge!
