- Mage of Infinity Merlin joins as a powerful new STR DPS hero.
- A new Transcendence hero tier has been introduced.
- The 777 Lucky Card Match event makes its return.
The Seven Deadly Sins: Idle Adventure continues its strong momentum following last month's launch of Wandering Swordsman Meliodas. Netmarble now unveils Mage of Infinity Merlin, a formidable STR DPS hero, accompanied by a brand-new hero grade and a series of limited-time events filled with rewards.
Mage of Infinity Merlin arrives in The Seven Deadly Sins: Idle Adventure through a Rate-Up Summon event, bringing devastating magical damage to your team. She is more than just a new addition; she is the inaugural hero of the newly established Transcendence grade.
This Transcendence tier ranks above Legendary and features unique passive Traits that empower your entire lineup. Only one Transcendence hero can be deployed per team, and unlike standard characters, they cannot be summoned. Acquiring them requires active participation in various in-game content and events.

Additionally, the latest update sees the return of the 777 Lucky Card Match Event, offering players a chance to win up to 777 times the reward from a single draw. The Elemental Mage Advent Event is also live, featuring a rotating reward table and roulette-style spins using event currency, alongside bonus rewards tied to your spending.

For players tackling boss content, a new challenge awaits. Galland of Truth has taken over the Advent Battle Boss rotation, replacing Derieri of Purity. Stage limits for both Normal and Nightmare difficulties have also been increased from 19,000 to 20,000, providing extended progression for committed teams.
