You and up to eight willing creatures within range fall unconscious for the spell’s duration and experience visions of another world on the Material Plane, such as Oerth, Toril, Krynn, or Eberron. If the spell reaches its full duration, the visions conclude with each of you encountering and pulling back a mysterious blue curtain. The spell then ends with you mentally and physically transported to the world that was in the visions.
To cast this spell, you must have a magic item that originated on the world you wish to reach, and you must be aware of the world’s existence, even if you don’t know the world’s name. Your destination in the other world is a safe location within 1 mile of where the magic item was created. Alternatively, you can cast the spell if one of the affected creatures was born on the other world, which causes your destination to be a safe location within 1 mile of where that creature was born.
The spell ends early on a creature if that creature takes any damage, and the creature isn’t transported. If you take any damage, the spell ends for you and all the other creatures, with none of you being transported.
For the duration, you or one willing creature you can see within range has resistance to psychic damage, as well as advantage on Intelligence, Wisdom, and Charisma saving throws.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can target one additional creature for each slot level above 3rd. The creatures must be within 30 feet of each other when you target them.
You drive a disorienting spike of psychic energy into the mind of one creature you can see within range. The target must succeed on an Intelligence saving throw or take 1d6 psychic damage and subtract 1d4 from the next saving throw it makes before the end of your next turn.
This spell’s damage increases by 1d6 when you reach certain levels: 5th level (2d6), 11th level (3d6), and 17th level (4d6).
