Fragmented memories

You have inherited the innate spellcasting from memories you can't quite place. This ability allows you to cast nondetection on yourself at will, without needing a material component. You can also cast each of the following spells once with this ability: Alter Self, Vampiric Touch, and Pass without trace. 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.
