The Seven Deadly Sins: IDLE Draw System and Summon Level Guide

In The Seven Deadly Sins: IDLE, you should spend standard summon tickets immediately to build summon experience, while holding premium Diamonds until higher Draw Levels unlock improved drop rates.

Unlike fixed-probability gacha banners, this game ties unit drop chances directly to your account's Draw Level. Pulling early with premium currency yields low-rarity units, making resource timing essential for acquiring top-tier heroes.

How the Draw Level Mechanic Works

Every pull you make contributes summon experience toward an overall Draw Level. Increasing this level alters the hero pool and improves your odds:

Low levels lock out top rarities: In initial levels, Legendary heroes either cannot drop or have extremely low pull rates. Common and Rare heroes make up the majority of the pool.
Higher levels expand the pool: Reaching higher summon tiers unlocks Legendary units and increases their baseline appearance rates.
Summon experience is cumulative: Every summon ticket or Diamond pull counts toward leveling up the system, making early pull volume the priority over hunting specific heroes.

Summon Level Breakpoints

Treat the initial levels as an investment phase where the goal is earning summon experience rather than chasing meta units.

Summon Stage	Draw Levels	Primary Hero Pool	Recommended Resource	Primary Objective
Early	Levels 1–5	Normal, Rare, Unique	Free and standard tickets	Accumulate summon EXP to unlock Legendary rates
Mid	Levels 6–8	Unique, early Legendary	Standard tickets and quest rewards	Expand roster depth and acquire duplicate copies
Late	Level 9+	High-rate Legendary	Diamonds and rate-up currencies	Target core carries and complete mileage goals

Legendary appearance rates begin to climb noticeably at Level 6. Level 9 and above serves as the primary target for premium currency, as it provides the highest baseline odds for Legendary heroes.

How to Allocate Tickets and Diamonds

To avoid wasting premium currency on low-value summon tables, follow these resource priorities:

Standard Summon Tickets: Spend these as soon as you earn them. Because standard tickets cannot be converted or used on special rate-up banners, their best function is accelerating your path through Levels 1 to 5.
Quest and Stage Tickets: Channel all campaign and quest reward vouchers straight into the basic summon pool to bypass early level rate penalties quickly.
Diamonds: Bank your Diamonds until your standard summon reaches Level 9, or use them on time-limited rate-up banners featuring high-priority carries.
Special Event Currency: Save event-specific summon tokens until you have enough to hit guaranteed reward thresholds during a specific event window.

Managing Mileage and Duplicate Heroes

The summon system pairs Draw Levels with a cumulative mileage counter. Every pull advances this meter toward fixed milestone rewards, such as extra summon vouchers, Unique hero chests, and Legendary selection tickets. Calculate your available ticket stash before committing to a session to ensure you have enough pulls to reach the next guaranteed milestone chest.

When you pull duplicate heroes, the system converts them into Hero Coins and unit-specific awakening materials. Applying these materials to star upgrades raises your team's base combat power, skill coefficients, and passive bonuses. If your campaign progress stalls due to combat power requirements, using tickets to generate duplicate awakening fodder provides an immediate stat increase. Once star levels are sufficient, pause pulling and resume saving resources for upcoming banner rotations.
