Just For Decoration
When confronted with dangerous situations, most garden gnomes just pretend to be inanimate. Most of the time, it works. Outside of combat you can make a performance check(contested by the enemy's investigation) to attempt to appear as a plastic garden gnome. If there are already garden gnomes present, you make this check with advantage.
Faetouched
You know the friends cantrip. When you reach 3rd level, you can cast the Faerie Fire spell once with this trait, and regain the ability to do so when you finish a Long Rest. Charisma is your spellcasting ability for this spell. You cannot be put to sleep by magic.
