All-Purpose Tool

As an action, you can focus on the tool to channel your creative forces. Choose a cantrip that you don't know from any class list. For 8 hours, you can cast that cantrip, and it counts as an artificer cantrip for you. Once this property is used, it can't be used again until the next dawn.

This feat allows you to pick the cantrip you want to add to your spell list as an Artificer cantrip.
