The Seven Deadly Sins: IDLE Legendary Hero Potential Stat Guide

To optimize Legendary Heroes in The Seven Deadly Sins: IDLE, assign Potential stats based strictly on each hero's team role. Offensive units require direct damage multipliers, while support units and front-line tanks need defensive stats to keep their buffs and mitigation active during stage pushes and boss encounters.

Stat Priorities by Role

Hero Role	Primary Stat Priority	Secondary Stat Priority
Main DPS	Attack %, Final Damage	Crit Rate, Crit Damage
Support	HP %, Damage Reduction	Evasion
Tank / Bruiser	HP %, Damage Reduction	Defense %, Attack %

Role Stat Breakdown

Main DPS

Primary attackers focus on maximizing raw output to push past high-defense enemies.

Attack Percentage: Raises base damage across all skill scaling.
Final Damage: Functions as a total damage multiplier to bypass enemy mitigation. Pure glass-cannon attackers, such as Traitor Meliodas, prioritize Final Damage and Attack exclusively.
Crit Rate & Crit Damage: Invest in critical stats only when a hero's specific skill kit requires critical hits to trigger passive abilities or burst mechanics.

Support Units

Support heroes provide value through active team buffs, debuffs, and healing. Their potential rolls must prioritize survivability because their team benefits vanish if they fall early in combat.

HP Percentage: Builds maximum health pools to absorb incoming area damage.
Damage Reduction: Decreases heavy burst damage from boss skills.
Evasion: Adds a secondary layer of defensive rng to survive high-stage enemy attacks.

Tanks and Bruisers

Front-line units require dual investment to maintain positioning and contribute passive damage.

HP Percentage & Damage Reduction: Primary defensive stats that ensure survival under concentrated enemy target fire.
Defense Percentage & Attack Percentage: Secondary choices that balance front-line durability with baseline damage output.

Efficient Rerolling Strategy

Rerolling Potentials consumes currency that can otherwise advance hero levels early in progression. Follow these guidelines to avoid resource bottlenecks:

Secure Stat Types First: Lock in the correct primary stat type (such as Attack % or HP %) before attempting to maximize percentage values.
Settle on Usable Rolls: Stop rerolling once a hero receives a functional stat for their role. Chasing a minor upgrade from a medium roll to a maximum roll yields lower team gains than upgrading secondary heroes.
Limit Resource Spending on Supports: Reserve major reroll budgets for your main damage dealers. Support units only require basic defensive roll targets to perform their function.
