In-game description Edit
|“|| Unholy Word|
Uttering an Unholy Word spell creates magic of tremendous power. The priest acts as a bridge between his/her god and the Prime Material Plane, causing a small explosion centered on the priest and reaching up to a 30-ft. radius. It affects only creatures of any good alignment that are caught in the area of effect. The effects vary depending on the target's Hit Dice:
Hit Dice / Levels –– Effects of Unholy Word
Less than 4 –– Death
4 to 7 –– Stunned for 1 turn
8 to 11 –– Slowed for 1 turn with a 75%
chance of spell failure
12 and up –– Deafened for 1 turn with a
50% chance of spell failure
There is no Saving Throw. The effects are instantaneous and last for the duration of the spell or until dispelled. Note that priests of good alignment may not cast this spell.
