Components: V, S, M
Casting Time: 4 segments
Saving Throw: None
Area of Effect: 1 dagger

This spell will endow a dagger
with the power of flame or frost, as chosen by the caster.
Each power has an effect as described below.

Flame: The blade ignites like a torch, casting light in a 30-
foot radius. The flame will ignite any combustibles which
the blade contacts. The blade gains no magical bonus, but
will inflict an additional point of damage in melee. The
blade does three additional points of damage against coldbased
creatures, so a flaming dagger will inflict ld4 + 3
damage to a yeti.

Frost: The blade glows with a cold blue aura that sheds
light in a 10-foot radius. The blade has no magical bonus,
but will do one extra point of damage when it hits. The frost
blade will do three extra points of damage against a firebased
creature, such as a salamander or fire grue. The
blade can also freeze up to one cubic foot of water per round
when the blade is in contact with water.

The spell will have no effect on a weapon that already has a
flame or frost capability. 

MC: Phosphorous to produce a flame blade or quartz

crystal to create a frost blade.
