When you cast this spell, choose up to three creatures in range. Each of those targets must make a Wisdom saving throw. On a failure, the target’s perception of reality is broken and ever-shifting. The creature will see into one plane, smell another, feel another, and hear into a different one. Each round, the planes the creature perceives into changes for each sense. The creature is treated as if blind to all things not in the plane it is looking. While perceiving a plane, it is subject to all the effects of that plane from fire damage from the plane of fire to being attacked by demons in the abyss. Each round roll below to see where each of the creatures senses are for sight, sound, touch, and hearing.
|21-30||Plane of Air|
|31-40||Plane of Earth|
|41-50||Plane of Fire|
|51-60||Plane of Water|
Plane of Shadows
At Higher Levels: When you cast this spell using a spell slot of 7th level or higher, increase the number of targets by 1 for each slot level above 6th.
