Pestilence has powerful attack, and invincible defense. According to the keyword system on this very wiki:

Defense - Attack - There is no role that can kill a Pestilence at night, not even Pestilence. There simply isn't an attack tier high enough. The Coven Leader would simply die for visiting the Pestilence.
 * 1) None - Your role will die to any Attack.
 * 2) Basic - Your role is protected from Basic Attacks.
 * 3) Powerful - Your role is protected from Powerful Attacks.
 * 4) Invincible - Your role is protected from Unstoppable Attacks.
 * 1) None - Your role cannot attack players directly.
 * 2) Basic - Your attacks will kill any role with a Defense value of None.
 * 3) Powerful - Your attacks will kill any role with a Defense value of Basic.
 * 4) Unstoppable - Your attacks will kill any role with a Defense value of Powerful.
