In Children Of Morta the various Items that Uncle Ben crafts can be used by the family members, mostly as Weapons and Gear they can use in their adventures outside the house. The Bergsons will have new Abilities when they use these items.
Uncle Ben's Workshop can be upgraded in a similar way to how Skill Trees work, which will open new Crafting options for family members. This adds persistent progression to the game and is part of the RPG influences of the game experience.
