Spell:Prismatic Ray

When Prismatic Ray hits a target, it inflicts 1 of 7 different effects at random, with a 12.5% or 1 in 8 chance of inflicting a target with a second different effect from that 7. These 7 effects are detailed as follows:

Red Ray: 4 * Caster Level Fire damage. A successful Reflex save reduces the damage dealt by half.

Orange Ray: 5 * Caster Level Acid damage. A successful Reflex save reduces the damage dealt by half.

Yellow Ray: 6 * Caster Level Electrical damage. A successful Reflex save reduces the damage dealt by half.

Green Ray: Instant Death (ignores Death Immunity). Deals Constitution damage on a successful Fortitude save (Poison effect negated by Poison Immunity).

Blue Ray: Turns victim to stone. Fortitude negates.

Indigo: Victim is stricken with Fear status. Will negates.

Violet: Sends victim to another plane (Instant Death, ignores Death Immunity). Will negates.

Additionally, creatures with 8 HD or less that are struck with Prismatic Ray are automatically blinded for 12 to 48 seconds.

Note that Spell Resistance does not protect against any of these effects, including the non-damaging ones.

The highest item based damage, critical hit rate and critical multiplier bonuses apply to this spell, regardless of the type of damage enhanced.

The highest enhancement based damage, critical hit rate and critical multiplier bonuses apply to this spell, regardless of the type of damage enhanced.

Enhancement bonuses and item bonuses stack.

For example, if you have an item that grants +30% Force damage, increases Force critical rates by 9%, and increases the critical damage multiplier by 0.25, and another item that grants +40% Fire damage, increases Fire critical rates by 6%, and increases the critical damage multiplier by 0.5, Prismatic Ray will deal 40% more damage, while its critical hit rate increases by 9%, and its critical damage multiplier increases by 0.5, the spell benefiting from the highest property from each category.

Expanding on this example, if you had enhancement bonuses that granted +10% damage to Lightning and Acid spells, +3% to their critical hit rates, and +0.5 to their critical damage modifiers, and another set that granted +30% damage to Fire and Cold spells, +6% to their critical hit rates, and +0.75 to their critical damage modifiers, Prismatic Ray would receive, in addition to all item bonuses, +30% damage, +6% to its critical hit rate, and +0.75 to its critical damage multiplier.

Combining the two examples, the final adjustment from items and enhancements would be: +70% damage (30% + 40%), +15% (9% + 6%) critical hit rate, and +2.25 (1 + 0.75 + 0.5) critical damage multiplier.

Spell:Prismatic Spray is a conical version of this spell that can strike multiple targets.
