Prismatic Wall in Dungeons & Dragons 5e
Basic Rules (2014) - Modified
Prismatic Wall
9-level Abjuration
A shimmering, multicolored plane of light forms a vertical opaque wall--up to 90 feet long, 30 feet high, and 1 inch thick--centered on a point you can see within range. Alternatively, you can shape the wall into a sphere up to 30 feet in diameter centered on a point you choose within range. The wall remains in place for the duration. If you position the wall so that it passes through a space occupied by a creature, the spell fails, and your action and the spell slot are wasted.
The wall sheds bright light out to a range of 100 feet and dim light for an additional 100 feet. You and creatures you designate at the time you cast the spell can pass through and remain near the wall without harm. If another creature that can see the wall moves to within 20 feet of it or starts its turn there, the creature must succeed on a Constitution saving throw or become blinded for 1 minute.
The wall, which has AC 10, can be destroyed one layer at a time, in order from red to violet, by means specific to each layer. If a layer is destroyed, it is gone for the duration. Antimagic Field has no effect on the wall, and Dispel Magic can affect only the violet layer.
Prismatic Layers
| Order | Effects |
|---|---|
| 1 | Red. The creature takes 12d6 fire damage on a failed save, or half as much damage on a successful one. While this layer is in place, nonmagical ranged attacks can't pass through the wall. The layer can be destroyed by dealing at least 25 cold damage to it. |
| 2 | Orange. The creature takes 12d6 acid damage on a failed save, or half as much damage on a successful one. While this layer is in place, magical ranged attacks can't pass through the wall. The layer is destroyed by a strong wind (such as one created by Gust of Wind) |
| 3 | Yellow. The creature takes 12d6 lightning damage on a failed save, or half as much damage on a successful one. This layer can be destroyed by dealing at least 60 force damage to it. |
| 4 | Green. The creature takes 12d6 poison damage on a failed save, or half as much damage on a successful one. A Passwall spell, or another spell of equal or greater level that can open a portal on a solid surface, destroys this layer. |
| 5 | Blue. The creature takes 12d6 cold damage on a failed save, or half as much damage on a successful one. This layer can be destroyed by dealing at least 25 fire damage to it. |
| 6 | Indigo. On a failed save, the creature is restrained. It must then make a Constitution saving throw at the end of each of its turns. If it successfully saves three times, the spell ends. If it fails its save three times, it permanently turns to stone and is subjected to the petrified condition until it is freed by an effect like the Greater Restoration spell. The successes and failures don't need to be consecutive; keep track of both until the creature collects three of a kind. While this layer is in place, spells can't be cast through the wall. The layer is destroyed by bright light shed by a Daylight spell or a similar spell of equal or higher level. |
| 7 | Violet. On a failed save, the creature is blinded. It must then make a Wisdom saving throw at the start of your next turn. A successful save ends the blindness. On a failed save, the condition ends, and the creature teleports to another plane of existence (DM’s choice) This layer is destroyed by a Dispel Magic spell or a similar spell of equal or higher level that can end spells and magical effects. |
