-In [[dNetHack]], [[notdNetHack]] and [[notnotdNetHack]], the energy vortex and almost all other vortices (except for the [[yochlol]]'s stinking cloud form) take halved damage from blunt, piercing and slashing weapons.
+In [[dNetHack]], [[notdNetHack]] and [[notnotdNetHack]], the energy vortex has its speed significantly reduced to 8 and the dice for its shocking engulf attack are doubled (i.e. 2d6 from 1d6), while the dice for its energy-draining engulfing are tripled (i.e. 6d6 from 2d6). The energy vortex takes halved damage from blunt, piercing and slashing weapons, and it can be [[Ward (dNetHack)|warded]] by the [[User:Chris/dNetHack/Elder Elemental Eye|Elder Elemental Eye]] at any level of reinforcement.
 Energy vortices can generate randomly in the [[Law quest (dNetHack)|Law Quest]] if [[Oona]] is alive and her elemental affinity is electricity.

-The energy vortex is a very dangerous monster with a high [[speed]] of 20: most heroes encounter it well before they obtain a source of shock resistance, and must contend with both active shock attacks and a passive that deals level-based damage, as well as having their energy drained while engulfed by the vortex&mdash;in particularly bad cases, this can drain enough energy to the point where the hero's maximum energy is affected as well. The danger posed by energy vortices make them a tempting target for [[genocide]].
