You conjure a series of magical transparent teleportation barriers around a point of your choice within range, surrounding a 30-foot cube area centered on that point. Each barrier is a 30-foot square plane that fully encloses the spell's area. When you cast the spell, each creature that can see the spell's area can make a Wisdom (Perception) check against your spell save DC to notice the appearance of the barriers (no action). For the spell's duration, whenever a creature in the area attempts to cross one of the barriers at the boundaries of the area, it must make a Charisma saving throw. On a successful save, the creature exits the area normally. On a failed save, the creature is teleported instead, trapped within the area until the start of its next turn. A creature that fails its save can repeat it the first time on each of its turns that it crosses one of the barriers, exiting the area as normal on a success. When a trapped creature attempts to cross any of the barriers around the spell's area, it is instead teleported to an unoccupied space inside the spell's area within 5 feet of the barrier opposite the one that they crossed. The space in which the creature appears is otherwise as close as possible to the one they left. If the creature can't fit in any space within 5 feet of the opposing barrier, it is instead likewise teleported to the furthest exposed barrier face of the area from the point at which it triggered the effect. If a creature is forced to fall repeatedly through opposing sides of the area, it is slowed to a safe falling speed each time it teleports, such that ending the spell doesn't cause the creature to sustain any damage from falling, and can move horizontally while falling, as if through difficult terrain. Objects worn or carried by an affected creature always travel with that creature. All other objects are always teleported as above when they cross the barriers, including weapon ammunition and thrown objects. This doesn't include non-solid spells or effects, such as a *magic missile* or *fire bolt*. Objects and creatures not within the area when the spell is cast can enter the area normally, but must then succeed on a Charisma saving throw to exit. ***At Higher Levels.*** If you cast this spell using a spell slot of 5th level or higher, the duration is 8 hours. If you use a spell slot of 7th level or higher, the duration is 24 hours. If you use a 9th level spell slot, it lasts until dispelled and doesn't require concentration. \columnbreak ### Dark Monk *Suggested by @whistlehunter* Though they may have been something of a monastic order once, the beings known now only as Dark Monks are nothing more than unholy husks of men who have surrendered their bodies to powerful fiends. These creatures appear ghastly and wraith-like, and conjure dark magic to give themselves deadly ability, and to call forth demons from the abyss.
