Domain Expansion

The area in a 30-foot radius centered on your position when you cast the spell takes on the characteristics of one of the wards of the Underworld. The area does not move with you after the initial cast. When you cast the spell, you can choose a number of creatures to be unaffected by the area's effects, and you choose one of the following effects to exist within the area for the duration of the spell:

• Agonas: The area is covered in sharp, jagged rocks and is difficult terrain for all creatures other than you.  Creatures take 2d6 piercing damage for every 5 feet that they travel.  You can choose a number of creatures up to your Wisdom modifier to be immune to the effects of this terrain.
• Phylias: You choose whether to raise or lower the affected area by up to 50 feet.
• Ilysia: Friendly creatures within the radius gain temporary hit points equal to your cleric level.  These temporary hit points refresh if they are within the radius at the end of their turn.
• Nerono: The area becomes a swirling whirlpool that is difficult terrain for all creatures other than you. Creatures that start their turn in the area must make a Strength save against your spell save DC or be pulled 10 feet closer to the center and cannot move away from the center for the remainder of their turn.  You can choose a number of creatures up to your Wisdom modifier to be immune to the effects of this terrain.
• Tizerus: Creatures that enter the area for the first time on a turn or start their turn in the area must succeed a Constitution saving throw or gain a level of exhaustion for the duration.
