Greater Boomshine (3.5e Spell)

A glowing sphere drops from the heavens like a small sun, and in a flash and a earth-shattering boom it vanishes, taking the undead army with it.

Creatures in a 30 foot radius spread take 1d8 points of damage per level (max 20d8 at 20th) and must make a Will save or be blinded and deafened permanently. Undead or creatures which take more damage from [Light] attacks take 10 damage per level (max 200 damage at 20th). Light sensitive undead creatures (such as wraiths) take 20 damage per level (max 400 damage at 20th). The save negates the blindness and deafness and halves the damage.
