Seven Deadly Sins: Idle Adventure Welcomes New STR-Attribute Debuffer: The Serpent Sin of Envy Diane!
Netmarble is shaking things up in The Seven Deadly Sins: Idle Adventure with the arrival of a powerful new hero. Even in an idle game, strategic combat is key, and the addition of The Serpent Sin of Envy Diane—the third Legendary Diane—as a STR-attribute debuffer significantly alters the meta.
This new character is available via Rate Up Summon Tickets or Diamonds until December 17th. The update also introduces Nightmare Stages, where players collect Nightmare Traces. These Traces can be exchanged for Gems at the Wandering Merchant Shop or earned through the Wandering Merchant’s Suspicious Missions event. Nightmare Traces are crucial for equipping Mystical Gem Boxes, providing essential buffs—especially beneficial when facing the formidable Advent Battle Boss, Galland.
