Ghost Smiting

( Ghostwalk, p. 34)

[General]

You can use your smite ability (smite evil for a paladin, smite undead for a Deathwarden chanter, and so on) to smite ghosts.

Prerequisite

WIS 13, smite ability,

Benefit

You may use your smite ability to smite ghosts. All normal rules for your smite ability apply, except that you may use the smite on ghosts as well as on your original sort of smite target, whether or not the ghost would normally qualify for your smite (a paladin could use her smite evil ability to smite a neutral or good ghost, for example).
