Chill of the Grave

Through your studies or prayers, you uncover secrets of necromancy that empower you and your creations with the deathly chill from the beyond. You gain the following benefits:

• You learn the Armor of Agathys, and you can cast it once per long rest at its base level without expending a spell slot. Intelligence, Wisdom, or Charisma is your spellcasting ability for this spell (choose when you select this feat).
• Whenever you would create(directly or indirectly) a Skeleton, Zombie, or Ghoul, you can create a Shadow instead.
• Undead creatures that you create(directly or indirectly) have a number of temporary hit points equal to your character level. While they have these temporary hit points, they gain the following benefits:
  • Their melee attacks deal an additional 1d6 cold damage.
  • Creatures that hit them with a melee attack take 1d6 cold damage.
