Aberration
The aberration is a monster class that appears in xNetHack, represented by the uppercase U glyph (U). It is designated internally by the macro S_ABERRATION. The aberration class "replaces" the umber hulk monster class from vanilla NetHack, which has the titular monster as its only member, and includes several other
Aberrations consist of the following monsters:
- U umber hulk
- U mind flayer (formerly h)
- U master mind flayer (formerly h)
- U quantum mechanic (formerly Q)
- U genetic engineer (formerly Q)
Strategy
The presence of mind flayers in the monster class serves primarily to avert the YASD potential from using a blessed scroll of genocide on them as a dwarven player - this change additionally solves the problem of "minesflayers", which occurred in vanilla NetHack as a result of initial level creation for Gnomish Mines floors outside of Minetown and Mines' End ignoring out-of-depth rules when placing a random humanoid monster.
