The Dragon's Mark

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 with this ability: [spell]Power word kill[spell]Bones of the earth[spell]Animal friendship, Beast bond, Dominate beast, Instant summon[spell]Animate dead, Create dead, Raise dead, Speak with dead. [Spell]The vorpal sword summon. You regain the ability to cast these spells when you finish a long rest. With this ability you also gain the power to summon a beast companion and a familiar.

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