Domain Expansion: Call Of The Void

A technique Unique to oneself it affects an area adding an advantage/making an attack or assuring a hit. 60-foot around the user a black sphere is formed where the target is pulled into the users domain acting similarly to a temporary pocket dimension 

Squirming, ebony tentacles fill a 60-foot square on ground that you can see within range. For the duration, these tentacles turn the ground in the area into difficult terrain.

The Radiant energy helps form the changing terrain helping to form the main attack

Necrotic energy spreads hungering for any targets 

 And From The power of the Aether the true danger is revealed through the damage the soul of the target takes inside the domain

When a creature enters the affected area for the first time on a turn or starts its turn take 1d6 bludgeoning damage, 1d6 Radiant damage 

1d6 for Aether damage (damage to the soul if too much is taken it overall cripple its target)

1d6 necrotic damage 

When the main attack is released the domain will end after the tentacles squeeze the target damaging the outside as the Radiant damage harms the inside while the Aether damage damages the soul 

1d100 rolled and 1d4 for the distribution of damage
