This spell creates an unholy, chaotic dirge that fills the subject's head with the screams of the dying, the wailing of the damned, and the howling of the mad. Affected creatures suffer a -4 profane penalty to attack rolls and Concentration checks, a -8 enhancement penalty to effective Dexterity (with Reflex saves reduced accordingly for the spell's duration), and halved movement due to the subject's equilibrium being thrown off by the dirge.

Dirge of Discord is from WotC
