Spell words are an all but forgotten subsystem in Pathfinder. We still love them. So today being Friday, I pulled up a few from Book of Magic: 10 Undead Spell Words and decided to share them.
Fade From Undead (Concealing)
School abjuration; Level cleric/oracle/warpriest 1
Duration 1 round/level
Saving Throw Will negates (harmless); Spell Resistance yes (harmless)
Target Restrictions selected
The target of a wordspell with this effect word becomes invisible to undead creatures. If the target attacks or otherwise takes an offensive action, this effect ends.
Boost: The target cannot be detected by undead creatures through any means. Boosting this effect word increases its level by 1.
Sunlight Flash (Illumination)
School evocation; Level cleric/oracle/warpriest 3, inquisitor 3
Duration instantaneous Saving Throw none; Spell Resistance yes
A wordspell with this effect word releases a flash of sun light. A creature that is targeted by this effect word sustains 1d8 points of damage per two caster levels (maximum 5d8). An undead creature takes 1d6 points of damage per caster level (maximum 10d6); an undead creature particularly vulnerable to bright light takes 1d8 points of damage per caster level (maximum 10d8). A construct or inanimate objects takes 1d6 points of damage per two caster levels (maximum 5d6). If the wordspell has only a single target, it requires a melee or ranged touch attack.
