No, thanks for the criticism, I'm trying to make it the best it can be, and the more people that weigh in the better it should end up. Legacy based is interesting to me, since really the power comes from the stones, and grows with the characters. That might be the way to go, but I'll have to wait about a month to be able to get to my legacy book. The increase to strength and constitution also sounds like it would work in place of the damage reduction, but the legacy thing could work well with that too.

I made it 5 level PrC since in game they had 5 D'Levels, but the characters themselves gain roughly 18 levels (6 in a d&d system) by the time they get their dragoon to 5. I'm really liking the legacy idea, and I think that I could incorperate all of the ideas everyone's had into it. Just have to wait awhile on the book, unless I actually have it with me.
