Weird effect, but I think I can go along with what you're talking about so far.
By the way, why aren't we using "all-around vision" like the xorn? That's the standard ability, and let's also recall that 3.5 doesn't have facing (except in optional UA rules).
I'd rather stick to the normal SQ, surprise, surprise. Reflavoring makes sense, of course.
Hmmm, that's a majority.Will my response be as surprising?
Will my response be as surprising?
Either my Sarcasm check or Sense Motive check failed. Regardless, I am fond of sticking with the traditional all-around vision SQ.
As for soften, it looks a good start. I'm not sure the aurotyugh should decide whether DR or armor is reduced; I'm thinking it should either affect both at the same time, or soften armor first, and move on to DR on consecutive strikes.
How about this revision...
Soften (Su): Aurotyughs can soften any material they touch, including metal, stone, and hard living tissues such as bone or chitin. The aurotyugh can soften any opponent or object it hits with an attack roll. If the opponent is wearing any armor, the soften attack affects the armor. If the opponent is not wearing armor, or armor that has been completely softened by previous attacks, the opponent is softened instead. A living creature or magic item can negate the soften attack with a DC Y Fortitude save. For each successful soften attack, the target (or its armor) suffers a -X penalty to its armor bonus, hardness, natural armor bonus and any damage reduction that is bypassed by any mundane material. The effect last for 10 minutes. The save DC is Constitution-based.
