Candletrap

As you cast this spell, you arrange the candles in a circle with a 5 or 10-foot radius on the ground or the floor. When you finish casting, magical energy fills the circle to a height of 20 feet for the duration, and the cylinder becomes a magic trap.

The trap is triggered when a Construct, Shapechanger, or Undead creature moves into the cylinder. The circle affects the creature in the following ways:

• The creature can't willingly leave the cylinder by nonmagical means. If the creature tries to use teleportation or interplanar travel to do so, it must first succeed on a Charisma saving throw.
• The creature has disadvantage on attack rolls against targets outside the cylinder.
• Targets outside the cylinder can't be charmed, frightened, or possessed by the creature.
