❓ Frequently Asked Questions
Q: Is Duet Night Abyss a gacha game?
A: Only for cosmetics — there is NO character or weapon gacha. All gameplay-affecting content is earned through progression, making it very F2P-friendly.
Q: How to get more Secret Letters for character unlocks?
A: Complete daily missions (15 clues per day), side quests, open chests, and participate in events. Convert 10 Secret Letter Clues into 1 Secret Letter.
Q: Which character should I level up first?
A: Focus on a single strong DPS like Rebecca or Truffle & Filbert. Concentrating resources on one main DPS will speed up your progression significantly.
Q: How long does it take to unlock a character?
A: You need 30 Character Thoughts. If you focus on daily missions (15 clues/day = 1.5 Secret Letters per day), active players can unlock a character in approximately 2-3 weeks with consistent play.
Q: What is Phoxene energy and how does it work?
A: Phoxene is the combat resource that powers your ranged weapons. You generate it by using melee attacks and spend it on ranged attacks. Managing this energy is key to combat effectiveness.
Q: Can I get all characters without spending money?
A: Yes! All characters can be unlocked through gameplay. The game is designed to be completely free-to-play friendly. Spending money only provides cosmetic benefits.
Q: What should I do with duplicate character thoughts?
A: After unlocking a character (30 thoughts), additional thoughts can typically be exchanged for other resources or used to enhance that character. Check the in-game shop for conversion options.
Q: Are there any limited-time characters?
A: No. All characters remain permanently available to unlock through the Secret Letter system. Events may provide faster unlock methods, but no character is truly time-limited.
