Variant Salt Gnome
Artificer's Mark. Salt gnomes are occasionally born with a knack for inventiveness and artifice, rather than for practicality. Instead of the Toughness trait, you can cast the find familiar spell once with this trait, requiring no material components, and you regain the ability to cast it this way when you finish a long rest. Intelligence is your spellcasting ability for this spell. When you use this feature, your familiar is a construct instead of the normal type.
