What to Do Now

• F2P players: Prioritize missions that award AP and credits early to sustain farming during the event period. The cumulative Eleph boxes are high-value for ascending key students.
• Low-spend players: Check your account creation date to confirm which reward track applies. If you are close to the cutoff, verify in-game.
• Optimal players: Complete missions in any order, but aim for the 30-mission cumulative reward to secure the Secret Tech Notes. Claim rewards promptly—mail expires after 7 days.
