He has taken a run at the Valkyrie class and asked for some comments and suggestions. This post identifies a few changes I would make.
While working on it I felt a huge urge to crank up the death aspects of it, and possibly make it more design. Shift it from “cold fighter with a bit of death” (which might be reasonably close to the NH source material we’re modeling) to (eventually) “avatar of frost and death” — grant a mix of cold and death powers. The spell casting looks too good, it should probably be backed off a fair bit — perhaps replace it with a reduced Sorcerer casting progression (where the first two spells of each level must be related to cold and death). For now though, I’ll stick to tweaks.
The Valkyrie gets a weird mix of abilities from several different core classes because I’m trying to model the feel and play of the Nethack Valkyrie. Among other things, they get the “Speed Intrinsic” at XL 7. I have chosen to model this using the flurry of blows ability (as done in the RSRD Monk; I didn’t think the Pathfinder Monk flurry of blows fit as well here).
I may take another run at this later, starting from first principles.
