Now this week I'll kick off with a five color spell.
Prismatic Blast
Evocation [White, Blue, Black, Red, Green, Fire]
Level: 9
Acquisition: WWUUBBRRGG
Components: V, S, M
Casting Time: 1 action
Range: Close
Area: Burst to the extent of the range excluding up to 1 creature / 3 levels and yourself.
Duration: Instantaneous
Saving Throw: See Text
Spell Resistance: Yes
A burst of prismatic energy strikes for 10d6 fire damage (red, reflex 1/2), then deals 10d6 more damage to undead and constructs (green, fortitude 1/2), then deals an area dispel as per greater dispel magic (white, no save - caster level check required), then slows all creatures in the area as per slow (blue, will neg.) and finally deals 1d6 constitution ability damage to all creatures in the area (black, fort 1/2). Each effect is saved for seperately. Spell resistance can negate the whole spell. Although you are at the center point you, your familiar, and up to 1 creature you designate / 3 levels is unaffected.
Material Component: Colored sand
