(Evocation)

Range:  0
Components:  V, S, M
Duration:  Instantaneous
Casting Time:  4
Area of Effect:  1-foot wide, 10-foot + 5-foot per level long beam
Saving Throw:  Negates

This spell is very much like the 2nd-level rainbow beam spell, but is much more powerful. Besides a slightly larger area of effect, and the fact that a solid object will not stop the beam unless larger than 2 feet wide and formed of solid stone or some such similar dense material, i.e., the beam is not stopped by mere flesh, even if armoured, but would be stopped by a stone wall.
The spell does 1d6 HP of damage + 1 HP per level of the wizard. The swirling, coruscating tendrils of multihued light also have properties as listed under the rainbow beam spell. A target resistant to one or more of these forms of attack takes one less point of damage per die per attack that it is resistant to. The opposite applies for creatures that are particularly vulnerable to a certain form of attack (for example, a frost giant is immune to cold, but is not particularly vulnerable to fire, so it would take one less point of damage per die. A green slime, vulnerable only to fire and cold, would take 5 fewer points of damage per die). The indigo (holy water) beam does normal damage except to creatures affected by unholy water (paladins, lammasu, etc., who are considered being resistant), and those affected by holy water (undead, demons, etc., who are considered specifically vulnerable).
The victim is entitled to a saving throw, which, if successful, indicates that the beam has missed. It may hit another target, though. Also, if a target is struck by the beam, he must save versus petrification or be struck in the face and blinded for 1d4+2 rounds.
The material component for this spell is a small diamond worth not less than 100 gp.
