Rainbow shield

Rainbow shield was an abjuration and evocation wizard spell.

Effects
This spell enveloped either the caster or a willing target with shimmering colors that changed with the target's mood. A rainbow shield was used in conjunction with one other mid-power harmful spell, such as fireball, which was cast into the shield. The rainbow shield would reflect the effect of the harmful spell back to anything that attempted to physically harm the target while the shield endured. This reflective strike did not occur if the shield recipient was attacked with missiles or other magical strikes.The caster was unable to recast the selected harmful spell while the rainbow shield remained active.

Components
In addition to verbal and somatic components, this spell required as material components an iridescent shell to cast.
