Sign of Koth

7th-level abjuration (void magic)

Casting Time: 1 action
Range: Touch (60-foot radius)
Components: V, S, M (a platinum dagger and a powdered black pearl worth 500 gp, which the spell consumes)
Duration: Until dispelled

You invoke the twilight citadels of Koth to create a field of magical energy in the shape of a 60-foot-radius, 60-foot-tall cylinder centered on a point you can touch. The only visible evidence of this field is an inky black rune that appears at the spot touched and on every doorway, window, or other portal inside the cylindrical area.

Choose one or more of the following types of creatures: aberrations, beasts, celestials, dragons, elementals, fey, fiends, giants, humanoids, monstrosities, oozes, plants, or undead. The sign affects creatures of the chosen type (including you, if applicable) in the following ways:

  • Those creatures can't willingly enter the cylinder’s area by nonmagical means; the cylinder acts as an invisible, impenetrable wall of force. If an affected creature tries to enter the cylinder’s area via teleportation, a dimensional shortcut, or other magical means, it must make a successful Charisma saving throw or the attempt fails. Affected creatures are deafened to all sounds that originate from inside the cylinder.
  • Affected creatures have disadvantage on attack rolls against targets inside the cylinder.
  • Affected creatures can’t charm, frighten, or possess creatures inside the cylinder.

Creatures that aren’t affected by the field and who take a short rest inside it regain twice the usual number of hit points for each Hit Die spent at the end of the rest.

When you cast this spell, you can choose to reverse its magic; this will prevent affected creatures from leaving the area instead of from entering it, deafen them to sounds from outside the cylinder, etc. In this case, the field provides no benefit for taking a short rest.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the radius increases by 30 feet for each slot level above 7th.
