SLASH'EM_0.0.7E7F2/monst.c#line907

Like dretches, rutterkin, and blood imps, nupperibos are minor demons that are broadly similar to imps, sharing their speed and regenerative abilities but having a different base level and attacks.  Nupperibos have a decently powerful poison-branded attack, but appear late enough that the player will likely have MC3 or poison resistance before meeting them.

The constitution-draining effect of metamorphosed nupperibos is not poisonous in nature, so poison resistance will not protect you.  It is, however, blocked by magic cancellation.  Against other monsters, these attacks deal an extra 1d10 damage.
