In the first round of combat, this foul creature speaks its vile utterance, vomiting forth its perversion of the power of Truespeech. It then uses the Recitation of the Fortified State and the total defense action to protect itself from harm until it can use its utterance once more. Even when taking the total defense action, a painspeaker moves aggressively toward lighter armed and armored creatures, hoping to force them into provoking attacks of opportunity when they move away.

Utterance of Pain (Sp): Once every 3 rounds, a painspeaker can use a reversed moderate word of nurturing utterance as a 6th-level truenamer. Unlike normal uses of an utterance, this ability is not subject to the law of Resistance, so repeat uses in a day do not add 2 to the DC of its Truespeak checks.

Skills: Painspeakers have a +10 racial bonus on Truespeak checks

Painspeakers are twisted undead creatures with sickening gray flesh drawn tight over their bones. They were once humanoids who died with some important message left unsaid, whether a courier who failed to deliver an entreaty for peace, a hopeful lover who failed to speak her heart, or a witness who failed to step forth and speak the truth. For these creatures, death and the failure to speak were the same anguish. Having risen because of the tortured words that they failed to utter, painspeakers now give voice to their pain in Truespeech, blighting the lives of others with the power of the spoken word.

A painspeaker resembles the person it had been when alive. Someone who knew the painspeaker before its death might recognize it with a DC 20 Spot check.

A painspeaker speaks the languages it knew when alive.
