Level: 5
Range: 5 yds/level
Duration:  2 rounds/level
Components: V, S, M
Casting Time: 5 segments
Saving Throw: None
Area of Effect: 20' square

This spell creates a screen of
energy drawn from the quasi-elemental plane of radiance.
The screen can be up to 20‘ 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.

Red energy: cold energy ( + 1 damage to fire-based, none if
cold)

Orange energy: heat energy (+ 1 damage to cold based,
none if fire)

Yellow energy: acid damage (save vs spells or take +2
splash)

Green energy: neutralize poison

Blue energy: electrical energy ( + 10 damage to metal
armored)

Indigo energy: undead specific (only undead harmed)

Violet energy: vegetation specific (only plants harmed)

The screen will affect anything passing through it as if the
creature were being attacked by energy or matter of the
type 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
will inflict two points of damage per level of the caster.
Cold-based creatures will take three points of damage per
level of the caster when passing through the orange screen,
while fire-based creatures will suffer three points of damage
per level from the red screen.

MC: A crystal prism, a beryl gemstone worth at least 500
g.p., and a thin sheet of fine crystal colored the seven colors
of the rainbow, all of which vanish after the spell is cast.
