Bonded items

Bonded items are powerful numenera artifacts that go in the two Bonded equipment slots on the Inventory screen, to the right of your character. When equipped, they fuse directly to your skeleton, nervous system, or organs, providing significant positive effects, but their invasive nature can also produce negative effects. The Concentration skill allows you to equip bonded items without suffering the negative effects: Trained gives you one free of charge and Specialist two.

You can equip up to 2 Bonded items at once. If your Concentration Skill is at the Novice level, both items inflict their negative effects. If Trained, you ignore the negative effects from the first item. If Specialized, you shrug off all negative effects from Bonded items. If your Skill level is Inability, one of your Bonded slots is locked until you improve the Concentration Skill.
