Chromatic Blade

This spell creates a shimmering blade of constantly changing hue, of needle-width and magical sharpness. It weighs nothing and makes no sound upon impact. The blade glows at all times with a gleaming shimmering radiance that flickers between colors continually and uncontrollably casting dim light in a 5' radius. It is safe to touch a chromatic blade only at its hilt or guard; the blade itself is all edges and even its lightest touch will cause harm. 

Attacking with the blade is a melee spell attack. Its merest touch inflicts 2d4 + casing ability modifier points of Force damage and it can sever extremities like a sword of sharpness (see table).

The bearer of a chromatic blade is protected from color spray attacks (Chromatic Orb, Color Spray, Prismatic Spray, etc.), which will scatter upon the blade as soon as they come into contact it.

A prismatic spray can be likewise scattered but the blade loses 1 round of duration.

The blade can destroy one color of a prismatic sphere or one color of a prismatic wall upon contact but the blade is destroyed.

A great blow can be struck with the blade so as to shatter the entire sphere or wall, but has a 50% chance to suffer the effects of all of the colors simultaneously (Save as normal) while leaving the barrier intact.

A chromatic blade is not affected by changes in light or darkness or by magnetic effects. The blade cannot be mentally wielded or influenced from a distance except for the caster willing it out of existence.
