Netmarble is shaking things up in the world of *The Seven Deadly Sins: Idle Adventure*, proving that even in an idle game, you can still pack a punch. Get ready to welcome the new STR-attribute Debuffer, The Serpent Sin of Envy Diane, to your team. As the third Legendary Diane in this RPG, she's set to change the meta and bring some serious debuffing power to your lineup.

With the latest update, you have until December 17th to snag this new character using Rate Up Summon Tickets or Diamonds. Dive into the Nightmare Stages to test your combat prowess and collect Nightmare Traces. These can be exchanged for Gems at the Wandering Merchant Shop, and you can also earn them through the Wandering Merchant’s Suspicious Missions event.
