Saturate the ground with Abyssal energy to create an obstacle for your enemies. For the duration, the ground in a 20 foot square from a point within range becomes Abyssal Terrain. Creatures that start their turn in or move to a space covered in Abyssal Terrain must make a Wisdom or Strength saving throw (their choice) or have their movement reduced to 0. Creatures standing in this Abyssal Terrain are Silenced for as long they are in it. A creature that ends its turn in this Abyssal Terrain with 0 movement must make a Strength saving throw against your spell save DC or become Restrained as their body sinks into the abyssal Terrain. A creature may use its Action to roll an Athletics check against your spell save to escape the Restrained condition. Lastly, a creature Restrained by this Abyssal Terrain takes 1d12 Abyssal damage at the end of its turn.
