6.5 Anniversary Character Tier List

The anniversary meta prioritizes Light and Dark Festival heroes. Because these attributes ignore the standard Red, Blue, and Green color triangle, they provide consistent damage alongside high base Combat Class (CC).

TierRoleCharactersKey Strengths
SSSMeta AnchorsDemon King Meliodas, UR Escanor, SabunakIrreplaceable team stat buffs, damage caps, and rapid elimination potential
SSTeam Engines & CarriesTranscendent Ban, Chaos Arthur, LR LudocielDominant racial passives (Human, Unknown, Goddess), debuff cleansing, and damage reduction
SHigh-Utility SpecialistsGawain, LR Roxy, LR Percival, MaelHigh single-target burst, stance removal, and dedicated sub-slot support passives
ADemonic Beast StaplesMegellda, Jormungand, Red Freyr, BrunhildTailored floor mechanics, passive stat scaling in beast battles, and Holy Relic farming

If you are rerolling an account or pulling on the primary Festival banner, prioritize securing at least one SSS-tier carry. Demon King Meliodas and UR Escanor dictate the pace of matches through allied stat boosts and ultimate gauge control, giving you a reliable backbone for both PvP and PvE content.

Demonic Beast and PvE Specialist Value

While SSS and SS units handle PvP and general campaign chapters, progression into endgame gear requires dedicated PvE heroes. Demonic Beast Battles require specific kits that standard damage carries cannot replace:

  • Megellda: Provides healing, stat increases, and ultimate gauge control tailored specifically for the Hraesvelgr (Bird) encounter.
  • Jormungand: Grants card resets and stat scaling designed to clear Eikthyrnir (Deer).
  • Red Freyr and Brunhild: Deliver consistent stance cancellation and high single-target damage to bypass boss thresholds in Death Matches and beasts.

Clearing these stages allows you to craft Holy Relics, which directly enhance the stats and passives of your frontline PvP units. Do not discard or neglect these A-tier specialists if you pull them on catch-up banners.

Diamond Budgeting and Banner Rules

Anniversary Festival banners feature a 900-Diamond guaranteed pity selector. Summoning without the resources to reach this threshold risks exhausting your reserves without securing a featured hero.

  1. Calculate your total reserve: Sum your current Diamonds, weekly PvP payouts from the Ungeared league, daily task rewards, and incoming code rewards before pulling.
  2. Commit to one banner: Do not split Diamonds between standard seasonal banners and the main Festival banner. Pool summons into the banner with the highest concentration of SSS and SS units.
  3. Stop at key milestones: Once you reach the 900-Diamond selector and claim your desired carry, stop spending unless you specifically need duplicate copies for Ultimate Move level milestones.

Resource Investment Priorities

Upgrading too many characters simultaneously drains critical progression materials like Super Awakening Coins, SSR Pendants, and Engraving Stones.

  • Build your core four first: Invest full Super Awakening, cosmetic upgrades, and engraved gear into your primary team of three frontline combatants and one sub-slot support unit.
  • Craft versatile equipment: Build standard Attack/Critical Damage and HP/Defense gear sets. These sets provide the highest general Combat Class and can be swapped between heroes as your team composition evolves.
