Echocalypse: Scarlet Covenant Alina Oath Unlock Guide

To unlock Alina’s Oath in Echocalypse: Scarlet Covenant, you must promote Alina to 7 stars, max out her dormitory affinity, and consume an Oath Ring in her Case profile menu. Fulfilling these conditions unlocks an exclusive wedding costume, specialized voice lines, and permanent baseline attribute bonuses.

Prerequisites to Finalize Alina's Oath

The Oath ceremony serves as an end-stage progression milestone for fully upgraded Cases. You cannot initiate the ritual until Alina meets three separate investment conditions:

• Reach 7 Stars: Advance Alina through all intermediate breakthrough tiers by collecting duplicate copies or character bio-chips from limited summon banners.
• Max Out Affinity: Send daily dormitory gifts to Alina to raise her affinity level to the covenant cap.
• Obtain an Oath Ring: Secure an Oath Ring pledge token, available through specialized event exchanges, VIP milestone tracks, or covenant packs.

Once all three benchmarks are met, navigate to the Case menu, select Alina's profile, and tap the unlocked Oath prompt to trigger the sequence.

Oath Rewards and Stat Bonuses

Completing the ceremony locks permanent visual and functional upgrades to your account:

• Cosmetics and Audio: Grants Alina's wedding-themed skin, custom assistant animations on the home screen, unique profile frames, covenant emblems, and exclusive voiced dialogue lines.
• Permanent Stat Buffs: Grants flat increases to Alina's base HP, Attack, and Defense. These flat gains scale across your account with external systems such as gear, Neoliths, and Chimera synergies, providing a permanent boost to team Combat Power.

Should You Invest to Reach 7 Stars?

Pushing Alina to 7 stars requires spending a heavy reserve of Iridim and draw vouchers across banner rotations. Because the Oath is locked behind maximum star promotion, evaluate your roster before committing:

• Commit to 7 Stars: If Alina serves as your team's main anchor, carry, or primary frontline pillar. The combination of 7-star skill scaling, passive activation reliability, and Oath stats maximizes your primary win condition in PvP and high-difficulty PvE.
• Stop at 3 to 5 Stars: If your squad still lacks fundamental role coverage, such as dedicated crowd control, dispel units, or alternate burst DPS. Stopping at an intermediate star breakthrough gives Alina functional combat utility while preserving your currency for complementary Case banners.
