Svirfneblin Magic

You have inherited the innate spellcasting ability of your ancestors. 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: blindness/deafness, blur, and disguise self. 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.
