Prismatic Spray


Rainbow light representing the Prismatic Spray spell
Iris Here, with Humid Bow, Arthur Rackham, 1921.

Prismatic Spray throws a fan of unpredictable coloured magic across a 60-foot cone. The name survives across editions, but the ray table changes sharply: modern D&D uses damage-and-condition rays, while PF1e and D&D 3.5e retain the older lethal, petrifying, insanity and planar effects.

Eight rays flash through the cone. Every creature in it makes a Dexterity saving throw, then each target rolls 1d8 to determine its ray.

Edition Changes

What Changed?

  • 2024 adds Bard to the base class list; 2014, PF1e and 3.5e do not.
  • 2024 raises the damage rays from 10d6 in 2014 to 12d6.
  • Modern D&D removes the automatic low-HD blindness used by PF1e and 3.5e.
  • The green ray is radically different: modern D&D deals Poison damage; PF1e uses its poison subsystem; 3.5e can kill outright on a failed Fortitude save.
  • Indigo and violet remain control rays, but modern D&D resolves them through staged saving throws rather than the legacy insanity and immediate planar effects.

Play

Using Prismatic Spray

The spell is strongest when a caster can catch several enemies in the cone. It is intentionally unpredictable: one target may take straightforward damage while another is restrained, petrified or hurled to another plane.

Do not roll one ray for the whole cone. Each affected creature gets its own 1d8 result. On an 8, that creature alone receives two additional rays.

Edition warning: never carry the old 8-HD blindness or lethal green-ray poison into 2024/2014 play, and never replace PF1e/3.5e with the modern 10d6/12d6 damage table.
