race features:
Etheral Nature
You are a Humanoid, however, due to your connection to the Ethereal Plane, spells and effects that specifically affect Undead affect you as well.
Ethereal Vision
While you are on the Material Plane, you can see 120 feet into the Ethereal Plane.
Ghostly Descent
You float gently to the ground. At the end of a fall when you aren't incapacitated, subtract 60 feet from the distance you fell when calculating your falling damage.
Incorporeal Movement
You can move through other creatures as if they were difficult terrain. You can also move through solid objects, but your partially material form can't pass through more than one foot of stone, one inch of common metal, a thin sheet oflead, or 3 feet of wood or dirt. If you end your movement occupying the same spot as a solid object or creature, you are immediately shunted to the nearest unoccupied space that you can occupy and take force damage equal to twice the number of feet you are moved.
Spirit Speech
You can cast the speak with dead spell, without requiring a material component. When you cast the spell using this trait, you can ask the corpse a number of questions equal to your proficiency bonus, and you can't cast the spell with it again until you finish a long rest.
You can also cast this spell using any spell slots you have of the appropriate level. Intelligence, Wisdom, or Charisma is your spellcasting ability for this spell when you cast it with this trait (choose when you select this race).
