When this spell is completed the caster stores a ray of multi-coloured energies within themselves which they can release upon one target at any time within the 10 round spell duration.

Once unleashed the 3' wide thin ray (1' depth) emits from the caster's hands and strikes its intended target upon a successful ranged spell attack. If the ranged attack misses, the target suffers no effect. The ray is composed of three discernible colours - orange, blue and green - each one having a separate magical effect which strikes the target in that order.

The orange section of the ray inflicts fire damage equal to 12d4 making a small explosive sound when it strikes the target.  The blue part of the ray then inflicts a terrible weakness upon the creature, unless the target makes a successful Constitution saving throw with a +2 bonus, losing 1d4 points of strength permanently (Lesser Restoration, Remove Curse or any healing spell of 3rd level or higher can remove this affliction).  Finally, the last green part of the ray that hits is extremely bright and illuminous and when struck by its flashing light the creature must make a Dexterity saving throw against the spell save DC to quickly avert their eyes or be stunned motionless for 1 turn and blinded for a further 1-4 turns (a successful save indicates they averted their eyes in time and suffer no ill effects).

The caster must continue to concentrate while the spell is stored; if the concentration is broken through damage or another spell is cast that requires concentration or if the stored energies are not unleashed within the 10 minute duration, then there is a 10% chance the spell will backfire on the caster, otherwise it will just "fizzle out".

The material component for this spell are a small amount of orange, blue and green paint which must be smeared onto both hands while the spell is being cast.
