Bandai Namco has shared new details on its DLC plans for Ni No Kuni 2: Revenant Kingdom. The publisher will release three packs of additional content for the RPG over the next few months, the first of which is scheduled to arrive in August.

The Adventure Pack DLC launches on August 9 and will be available for free for everyone who owns the game. It adds an assortment of new challenges aimed at "experienced players." Along with new floors for the Faraway Forest Cave, the DLC introduces two new bosses to battle--Blackhart and Zeta--and additional quests that will be unlocked after completing the main story. Players will also be able to get new costumes and other rewards.
