You have inherited the innate spellcasting ability of your ancestors. This ability allows you to cast arcanist's magic aura on yourself at will, without needing a material component. You can also cast each of the following spells once with this ability: ray of enfeeblement, mirror image, and silent image. You regain the ability to cast these spells when you finish a long rest.

Intelligence is your spellcasting ability for these spells, and you cast them at their lowest possible levels.
