Within Duet Night Abyss, players select a primary character and activate others as support units during combat. These allies operate independently, offering tactical advantages without direct control. Strategic deployment of these partners can significantly alter battle outcomes.

This guide outlines effective strategies for preparing and utilizing allies to maximize their impact in the game.

Effective Ally Management Strategies

Preparing Support Units

Customize your allies through the Tactical Backpack interface by assigning character tokens and weapons. Each support unit may carry one primary weapon and enhancement modules. Selection requires careful consideration, as available slots vary: solo play permits two allies, while cooperative modes limit players to one companion each. Acquire Secret Letters through gameplay to expand your roster.

Activating Support Units

Access the Tactical Backpack during missions to activate pre-configured allies. These autonomous units require minimal supervision, allowing focus on primary objectives. Players may enable automatic deployment for repetitive tasks or low-difficulty scenarios, enabling passive completion of simpler challenges.

Optimal Ally Usage Scenarios

Strategic ally deployment proves advantageous in these situations:

• Resource Gathering Missions: Ideal for repeated completion of objectives without stamina limitations
• Stationary Defense Scenarios: Effective in confined combat zones where positioning remains static
• Cooldown Management: Maintain combat pressure during ability recharge periods
• Secondary Progression: Develop underutilized characters through passive participation
