This is one that has the monster graphical changes, the extra movement abilities deleted, and is geared specifically for Vanilla Play. Some special monsters remain as they are mascots to the monster mod.
The special monsters have been altered to be more compatible to pure vanilla difficulty. No more leaping imps and pinkys. Spectres are still shadow imps but are more normal speed now. Shadow knights still replace arachnotrons, Imp Elementals are still the same, and THe New Boss replaces the SPider Momma. All the Goat Knights still have their melee combo rush as well.
