Description: y plumbing the depths of eldritch knowledge, you have discovered dire secrets no mortal was ever meant to know.
Prerequisites: 20th Level Arcane Caster
Anyone other than you who speaks your name becomes greatly unnerved, as are all who hear it (other than you). If the creature who speaks your name has as many or more Hit Dice as you, he is shaken for 3 rounds (no save); if he has fewer Hit Dice than you, he is frightened for 1d4+1 rounds (no save). Creatures who hear your name must make a Will save (DC 10 + your arcane spellcasting level + your Cha bonus) or become frightened for 3 rounds. Even those who succeed on the saving throw are shaken for 1 round. Neither your presence nor knowledge of you has any effect on this ability. Your name itself has gained an inherent power all its own. This is a mind-affecting fear effect.
