The only reason I didn’t really include the class levels is because of the way the monster stat block works - all the information about the monster’s abilities are found in the stat block and the description of their special abilities, so I deemed the background info on it unnecessary to begin with; I think I’ll add a line showing what each level an awnshegh has is, though, for completeness’ sake. More awnsheghlien will be converted later; some were taken out of this manual during editing. There’s a project for converting awnsheghlien, NPCs and scions to these rules underway as well.
As for the question on monster abilities, that’s a tricky one - creating a full-blown system that would cover every conceivable ability and be balanced and internally consistent, would require a substantially larger section on this - possibly an entire book of its own. The guidelines as they are, are basically that the abilities should be similar to what existing characters or creatures of similar level/CR get; you might wish to apply the same principle as when designing a prestige class here - what a character should get for taking a level of awnshegh should be similar to, or better than, what that character would get for advancing a “normal” level. Once more awnsheghlien are out there with this system, it’ll probably be clearer.
As for ehrsheghlien, the reasoning here goes like this: They’re the “blood of light,” but only by comparison to the “blood of darkness” - i.e. you don’t have to be “good” to oppose “evil;” I certainly don’t think that all the old gods were good (they were given the equivalent alignment of their successors; if someone can come up with good arguments for why they’re different, I’m all ears). I can see a couple of holes in the system as it stands, though - for instance, chaotic evil “ehrsheghs” of Brenna - does not compute. I guess the best change to make here is to change the system “one step;” i.e. characters beyond one alignment step get the multiclassing penalty, and there can’t be any evil ehrsheghlien at all. If there’s any other suggestions, or better fixes, I’m eager to hear them.
Finally, an issue for the future in regards to awnsheghlien - I’d like to know if people think that a straight conversion, or a redesign works best for awnsheghlien. I can personally imagine arguments either way. The path that has been followed so far, has been more in line with a redesign than a straight conversion. I.e. the Gorgon has had some changes done to match the system that’s in place, and has been beefed up considerably, to follow suit for high-level 3e play. This is pretty necessary IMO; a straight conversion of the Gorgon would be much weaker than he is portrayed as being - same with most other awnsheghlien. Also, 3e has a lot of mechanical aspects to it that 2e didn’t have, so it makes sense to apply those standardized rules to awnsheghlien as well.
In order to illustrate, let me use an example of things that’s changed. Let’s take Rhuobhe Manslayer. Statistically, in 2e, he was pretty similar to a “mini-Gorgon” (and also the Raven and the Serpent, for instance - the typical 2e “path to power,” I suppose) -a fighter/mage. There were limited mechanics available for characterization. In 3e, should he be a ranger instead? Rangers couldn’t be evil in 2e - evil rangers became fighters. Ranger makes somewhat more sense for Rhuobhe in a couple of ways - specifically the favored enemy thing. There’s other things that can be argued as making less sense, like divine spells as well - of course, good elves could be rangers and get those spells in 2e anyway. Next, would he be a wizard, or a sorcerer? - again an option that didn’t exist before. Finally, let’s say we have a prestige class that’s geared towards the Gheallie Sidhe-type elves - would it make sense for Rhuobhe to exchange some levels in other classes for this? All this depends on how you look at Rhuobhe’s character as well, of course - shining elf knight gone bad, sneaky manhunter, a mix of the two, etc. Now, does it make sense to change around some of Rhuobhe’s levels a bit, in order to better fit him mechanically into the new system? I think, from the way I ask, it’s clear what I think, but I’d like to see if there’s substantial different opionions on this.
