Otiluke's Radiant Screen

This spell creates an immobile screen of energy drawn from the Quasi-Elemental Plane of Radiance. The screen can be up to 20 feet square, and can be shaped into a wall, hemisphere, or sphere as the caster orders. The radiant screen can be one of the seven colors of the rainbow, each color exhibiting a different form of energy identical to the colors of Nystul's radiant baton.

Color | Effect -------+---------------------------------------------------------------------------------------- Red | Cold energy (+1 damage to fire-based, none if cold) Orange | Heat energy (+1 damage to cold based, none if fire) Yellow | Acid damage (save vs. spell or take +2 splash damage) Green | Neutralize poison Blue | Electrical energy (+10 damage to metal armored) Indigo | Undead specific (only undead are harmed) Violet | Vegetation specific (only plant-based lifeforms, including fungi and molds, are harmed)

The screen affects anything passing through it as determined by the screen's color. The caster can change the color of the screen from round to round at will, but only one color per round can exist. The radiant screen inflicts 2 points of damage per level of the caster. Thus, cold-based creatures take 3 points of damage per level of the caster when passing through the orange screen, while fire-based creatures suffer 3 points of damage per level from the red screen.

The material components are a crystal prism, a beryl gemstone worth at least 500 gp, and a thin sheet of fine crystal colored the seven colors of the rainbow, all of which vanish after the spell is cast.

Notes: Uncommon or rare spell (WoG).
