Casting Time
10 minutes
You create a ward against magical travel that protects up to 40,000 square feet of floor space to a height of 30 feet above the floor. For the duration, creatures can't teleport into the area or use portals to enter the area.
In addition, the spell damages types of creatures that you choose when you cast it. Choose one or more of the following: Aberrations, Celestials, Elementals, Fey, Fiends, and Undead. When a creature of a chosen type enters the spell's area for the 1st time on a turn or ends its turn there, the creature takes 5d10 Radiant or Necrotic dmg (your choice when spell is cast).
You can designate a password when you cast the spell. Anyone speaking the password as it enters takes no damage.
