The Seven Deadly Sins: Gachiakuta Collab Codes and Banner Guide

To get the most out of the Gachiakuta crossover in The Seven Deadly Sins, redeem the eight collaboration gift codes before they expire and commit diamonds to the banner only if you can afford the 600-diamond guaranteed pity threshold.

Collaboration Coupon Codes and Redemption Steps

The event provides eight promotional codes covering summon tickets, upgrade materials, and stamina supplies. These codes are time-limited and subject to campaign expiration.

How to Redeem Codes

The redemption process depends on your platform:

• Android and PC: Open the in-game Menu, select Misc, tap Coupons, select the collaboration event tab, and enter the code.
• iOS: Go to the official Netmarble coupon redemption portal. Enter your Member Code (found under Player Info in your account profile), choose your server region, and paste the code.

Claim all rewards from your in-game mailbox promptly after submission, as unclaimed mail expires after a set period.

Evaluating Collaboration Unit Roles

Crossover units rarely receive post-launch balance updates, so their baseline mechanics determine their standing in PvP, Demonic Beast Battles, and Hero Arena.

• Top Priority (S-Tier Utility): Units that provide team-wide damage reduction, rank-up utility, or offensive stat multipliers that function outside mono-attribute teams. Heroes that buff the Unknown race hold high value due to established Unknown support backlines.
• Secondary Priority (A-Tier Counters): Attackers and counter-picks tailored against specific defensive setups, such as stance teams or buff-heavy burst engines. These units deliver competitive damage but may lack passive survivability or damage caps on turn one.
• Low Priority (B-Tier Specialists): Heroes restricted to event-specific farming, boss stages, or passive box Combat Class (CC) gains. These should be skipped if your summon resources are limited.

Team Synergy and Equipment

Most crossover heroes belong to either the Unknown or Human race.

• Unknown Teams: Position crossover units alongside backline support like Nanashi (with his Holy Relic) to gain defense, critical resistance, and attack scaling. Use an Attack/Critical Damage gear set with standard Attack, Defense, and HP sub-stats for primary damage dealers. For utility or gauge-depletion units, equip an HP/Defense set to maximize team Combat Class and secure the first turn.
• Human Teams: Pair Human-tagged event units with frontliners focused on single-target burst and weapon damage.
• Holy Relics: Craft event-specific Holy Relics through the collaboration exchange shop immediately. These use event materials rather than standard Demonic Beast drops and provide critical stat boosts that cannot be obtained after the event closes.

Diamond Budgeting: Collaboration Banner vs. Festivals

Collaboration banners feature a 600-diamond pity threshold, lower than the 900-diamond requirement for standard Festival banners. However, collaboration units, their duplicate coins, and their cosmetics rarely return.

• Free-to-Play Strategy: Do not spend diamonds unless you have at least 600 saved to guarantee the milestone reward. Only commit if the featured units fill an immediate gap in your roster, such as completing an Unknown team or expanding your Hero Arena lineup.
• Competitive PvP: Reaching higher ranks typically requires higher Ultimate Move levels for combat stats and CC. A 1/6 duplicate level often underperforms in high-tier PvP.
• Cosmetic Costs: Outfits for collaboration units cost between 180 and 270 diamonds in the shop and disappear when the event ends. Factor these costs into your budget if you intend to maximize a unit's secondary stats.

If you cannot reach 600 diamonds or your roster already clears your weekly Hero Arena and PvP targets, rely on the free draw tickets from codes and event missions and preserve your diamonds for upcoming Holy War festivals.
