How to Raise Combat Class in The Seven Deadly Sins

To raise Combat Class (CC) quickly in The Seven Deadly Sins, equip your main team with four-piece HP and two-piece Defense equipment sets, raise your association heroes to Ultimate Move level 6/6, and level your entire hero inventory to expand account Box CC.

Combat Class determines turn order in PvP and gates difficulty checks across high-end PvE stages. Because health values scale higher than attack or defense, stat gains focused on HP yield the largest direct CC increases.

Build HP and Defense Equipment Sets

Equipping a four-piece HP set combined with a two-piece Defense set delivers the highest raw CC increase on any hero. While offensive damage dealers may rely on Attack and Critical Damage sets for specific PvE damage checks, HP and Defense sets provide the highest raw score value when trying to meet CC requirements.

When upgrading gear pieces to SSR and engraving them to UR, focus on the bottom two slots first—the belt and the rune—because their primary attribute is flat HP.

When rerolling equipment substats with Anvils, invest only in basic attributes:

• Top pieces (Bracelet, Ring): Roll strictly for Attack percentage.
• Middle pieces (Necklace, Earring): Roll strictly for Defense percentage.
• Bottom pieces (Belt, Rune): Roll strictly for HP percentage.

Target substat rolls between 13.5% and 15% on each piece. Avoid secondary stats such as Critical Resistance or Pierce Rate when targeting CC thresholds, as secondary stats do not contribute heavily to the CC formula.

Maximize Association Units and Ultimate Move Levels

Heroes placed in the association sub-slots transfer a portion of their basic stats directly to the active frontline unit:

• At Ultimate Move level 1/6, an association unit transfers 5% of their basic stats.
• At Ultimate Move level 6/6, an association unit transfers 10% of their basic stats.

To capitalize on this stat transfer early, build easily accessible SR heroes whose Ultimate Moves can be maxed out to 6/6 using common silver coins, such as Green Gilthunder, Red Elizabeth, or Blue Guila. Equip these association heroes with complete five-star SSR HP/DEF gear sets with rolled basic stats to maximize the raw health and defense transferred to your primary fighters.

Prioritize Super Awakening and True Awakening

Awakening increases a hero's baseline attributes before gear multipliers apply. Complete standard 6-star Awakening on any combat unit before committing advanced currencies.

1. Super Awakening (Tiers 1–6): Focus your Super Awakening Coins and duplicate hero coins entirely on your four main team combatants. Do not distribute coins across wide rosters until your active combat team reaches tier 6. Once your frontline is maxed, super-awaken your primary 6/6 association units.
2. True Awakening: True Awakening requires Legendary Seals and high-tier evolution materials. Reserve these strictly for core festival heroes and key Demonic Beast carries to overcome late-game PvP and PvE stat barriers.

Raise Account Box CC for Constellation Buffs

Your account's total Combat Class (Box CC) combines the CC of every character in your hero box. Hitting cumulative Box CC milestones unlocks permanent account-wide HP buffs that apply to every team in all game modes, simultaneously advancing your progress through the Constellation system.

Never leave unused R or SR units sitting at level 1. Evolve them using low-rarity pendants and equip them with inexpensive HP/DEF gear sets. Awaken these budget gear pieces to five stars to rapidly add millions of collective HP to your total Box CC.

Register and Enhance Headpiece Cosmetics

Cosmetics provide permanent baseline stats that stack beneath gear bonuses. Every hero can register up to five weapons, five outfits, and five headpieces simultaneously:

• Headpieces grant flat HP.
• Outfits grant flat Defense.
• Weapons grant flat Attack.

Prioritize upgrading registered UR headpieces using enhancement materials gathered from Death Matches and Demonic Beast battles. Maximizing five UR headpieces provides thousands of flat health points, which are multiplied further by your HP gear sets and account-wide Box CC bonuses. Limit cosmetic upgrades to long-term festival characters and staple association units to manage upgrade materials efficiently.
