- The newest STR damage dealer arrives: Mage of Infinity Merlin
- Introducing the groundbreaking Transcendence hero tier
- Returning fan favorite: 777 Lucky Card Match event
The Seven Deadly Sins: Idle Adventure continues its thrilling rollout following last month's release of Wandering Swordsman Meliodas. Netmarble now unveils Mage of Infinity Merlin - a formidable STR-based damage specialist - alongside an innovative hero classification and exciting limited-time events loaded with valuable prizes.
Mage of Infinity Merlin debuts through a special Rate Up Summon event, delivering devastating magical attacks to your battle lineup. More than just another hero, she pioneers the brand-new Transcendence grade - the highest available classification.
This premium Transcendence tier surpasses Legendary status, granting unique passive abilities that enhance your entire squad composition. Teams may field only one Transcendence hero, obtained exclusively through dedicated gameplay and event participation rather than conventional summoning.

The update also sees the much-anticipated return of the 777 Lucky Card Match Event, where players can win rewards multiplied up to 777 times with single draws. Additionally, the Elemental Mage Advent Event features rotating prizes, roulette-style spins using event currency, and bonus rewards tied to participation levels.
