The Cornac entry in the Prestige Class Appendix II is broken.
The Animal Empathy, Cornac’s Will, Sensorium & Mind’s Touch class abilities for the Cornac are not defined in the class description at all. I assume Animal Empathy = Empathic looking at the class ability descriptions below.
1.) Arch Defiler should probably have Sickening Raze on its defiler / bonus feat list.
2.) It wasn’t clear to me if the Battle Dancer’s class ability Battle Dance has any limitations on it’s use besides a duration, and that isn’t clear if it is per day or per encounter / activation.
3.) As a manifester, shouldn’t the Cornac have Psicraft as a class skill?
Looking at it, I’m not clear what else would limit the Battle Dance, but to me it sounds like its initiating an ability by dancing, not maintaining it via the dance, mechanically speaking.
Just drawing on (I’m sure completely off-base) pop culture tropes, if it’s just similar(ish) to a Native American priest doing a “rain” dance and then an effect happening, the above seems consistent. If the Battle Dancer is supposed to be more like a Bladesinger and dancing the whole time, then the ability’s description seems off (but the PrC’s flavor text doesn’t really give me that kind of vibe).
Regardless, keep 'em coming as you see them, though, and I’ll get them in the errata list.
Yes, IMO both should stack. Though it’d have been nice if they made it more obvious, it’s pretty clear that an effort was made to let a character become both an Elementalist and Elemental Master.
Plus, at 11+ level, an extra 10 points of Fire Resistance (for instance) and a +1 DC to Fire spells isn’t a huge deal. Especially since the Elementalist’s capstone ability Ignore Element becomes much less important after you become an Elemental Master.
There are lots of problems in the two prestige class appendixes. Not just outright mistakes, but also game balance mistakes. Very stringent perquisites and weak class features seems to be the norm.
10 level prestige classes are supposed to have advancement past 20th level (Epic Level Handbook, pg 5), RAW, but I can’t see a clear progression for the Necromant. They get no bonus feats & no class abilities that improve with levels in the class aside from spellcasting.
Jaguar Roar seems to grant a non-existent feat, so it’d also be Ex. While we obviously know something about the feat from this text, IDK what its description might actually be. But, I’m happy to take suggestions.
For my purposes (mostly because I already had it scripted) I made it work like the Gladiator’s Threatening Glare except that it is sonic based & a Fortitude save vs Fear.
