UNDECEMBER, the hack-and-slash ARPG from LINE Games and NEEDS GAMES, launches its brand-new season “Trials of Power” on January 9, 2025. Packed with new solo challenges, revamped systems, and 3rd anniversary rewards, this update promises to keep Hunters grinding with fresh content and faster progression.

New Arena & Soul Stone Gear

The highlight of the update is the Arena, a new solo mode where players face deadly bosses like Ectasis and Manticore. Victories unlock Soul Stones, UNDECEMBER’s first Growth-type Gear, which can be leveled with exclusive Essences. These Soul Stones not only boost stats but may summon minion allies, adding new strategic depth to builds.

“Help! Hunters!” Chaos Dungeon Event

From January 9 to February 6, Chaos Dungeons feature the event “Help! Hunters!”. Players collect Ashes, convert Chaos Cards into Ash-covered Cards, and farm event currency to exchange for rewards like Essences and Unique Chests. Special developer-inspired ghost enemies add a humorous twist to the chaos.
