Features
Shared Presence
Beginning at the 3rd level, when you cast a spell you may cast the spell as if you were standing where your avatar is. Spells which use you as their point of origin may instead use your avatar as the point of origin. These spells do not cause damage to your avatar. You can use this feature three times. You regain expended uses of this feature when you finish a long rest.
Death Perception
Beginning at the 7th level, while your void avatar is within 100 feet of you, you can communicate with it telepathically. Additionally, as an action, you can see through your avatar's eyes and hear what it hears until the start of your next turn, gaining the benefits of any Special Senses that the avatar has. During this time, you are deaf and blind with regard to your own Senses.
Ravenous Rending
Beginning at the 11th, your void avatar can make two attacks when you command it to use the Attack action.
Reaper Art: Void Guardian
Beginning at the 15th level, as an action, you imbue the void avatar with immense necrotic energy. Any creature hostile to you that moves to a space within 10 feet of the Avatar for the first time on a turn must succeeed on a Dexterity saving throw against your Reaper spell save DC. The creature takes 20 necrotic damage on a failed save, or half as much damage on a successful one. The energy fades when it has dealt a total of 60 damage.
You may do this a number of times equal to half your proficiency bonus, rounded down. Uses of this feature recover when you complete a long rest.
