Pepper dust vs undead

Pepper dust blinds undead and gives an echo that it burns my eyes... though I have none. A wispy black cloud of dust rushes forth, stinging your eyes at its approach. A flesh golem yells 'Help! Otuerghad just filled the air with dust!' A flesh golem clutches its eyes and howls! Otuerghad's pepper dust EVISCERATES a flesh golem! A ghoul yells 'Help! Otuerghad just filled the air with dust!' The dust floats near a ghoul, but not enough to do serious harm. Otuerghad's pepper dust decimates a ghoul! The dust fills your eyes with burning pain! Someone's pepper dust MUTILATES you! The dust floats near someone, but not enough to do serious harm. Someone's pepper dust decimates someone! Someone is covered with bleeding wounds.
