The Seven Deadly Sins: IDLE Guide to Increasing Combat Power

To overcome progression bottlenecks and increase team combat power in The Seven Deadly Sins: IDLE, concentrate your hero EXP into a primary damage dealer rather than spreading resources across your entire team. Upgrading a main carry allows you to push past difficult stages, which increases your ongoing AFK reward rate and generates more growth materials for support characters.

Hero Leveling and Awakening Priorities

leveling your main carry creates an immediate power spike. Secondary support units require fewer resources to fulfill their utility roles and can be leveled after your primary damage dealer reaches a stage wall.

EXP Funneling: Concentrate limited character EXP into one primary damage dealer to clear high-level story stages.
Hero Awakening: Focus on awakening your main units once basic level caps are reached. Awakening grants percentage-based stat multipliers that outscale flat stat increases in later stages of progression.
AFK Reward Scaling: Use the power boost from your carry to unlock higher AFK reward tiers, accelerating the leveling speed of your sub-units.

Global Passive Skill Upgrades

Every unlocked character provides global account benefits through passive skills. These stat increases apply persistent bonuses to attack, defense, and HP across your entire roster, even when those characters are not active in your main combat party.

Check your hero menu regularly to claim and upgrade available passives:

Identify heroes with pending passive skill upgrades in your roster.
Prioritize passive skills that grant flat percentage boosts to core offensive and defensive stats.
Upgrade passive skills on unused low-rarity units, as their collective stat boosts accumulate across your entire account.

Refinement stones are a limited resource. Avoid spending refinement stones on low-rarity gear that will be quickly replaced. Save upgrade materials for high-tier equipment that yields long-term value.

Hero Role	Primary Substat Priorities	Investment Strategy
Main DPS	Attack, Critical Damage	Refine high-tier gear to maximize damage output
Tank	HP, Damage Reduction	Reserve refinement until acquiring permanent top-tier defensive gear

Match equipment substats directly to the unit's combat function so that gear upgrades translate into higher stage clearing performance.

Daily Routines and Diamond Management

Consistent resource collection prevents progression stalls. Make daily task completion a fixed routine before spending premium currency.

Daily Quests: Complete all daily quests to collect every tier of reward chest.
Dungeon Entries: Spend all daily dungeon entries to gather target upgrade materials.
Guild Activities: Participate in guild Content daily to secure shop access and active stat buffs.

When spending diamonds, avoid pulling on standard character banners. Save your diamonds for high-value banners featuring meta-defining units, or use them to purchase additional daily dungeon entries and energy. If your team hits a progression wall, spend hoarded upgrade materials to clear the stage; the increased AFK rewards from the higher stage tier will recover the spent materials over time.
