This guy has all the capability of being an absolute DM's worst nightmare. He can one-shot things as a dragoon with the best of them, buff up to become a pseudo-swordsage with the proper spells (complete with 9th level maneuvers), lay down the smack in stand-up melee with the divine buffs to withstand serious punishment, and lay down AMF's and other passive BFC inside a time stop with imbue arrow. Now, here's where it gets sick : if you can get mirror move and pump Int and Wis high enough (Int for DC's on Wizard spells and # of bonus feats from mirror move, Wis for DC's on Ur-Priest Spells and # bonus spells that SotAO uses for high level arcanes), you can take most if not all of those nice Dragoon feats, and further can also take things like Multishot, Greater Multishot, Rapid Shot, etc, and in place of sneak attack, use Hunter's Eye through Arcane Disciple. If all options are open, you'll be dropping from impossible heights on a spring attack on a target that is inside a silent AMF, doing sneak attack damage to boot, and before your turn is over launching 4 arrows all carrying sneak attack and 4d6 extra acid damage each from premanifesting Acid Sheathe. Now if I could only find a way to get a Swift Hunter out of this...you'd be set with the ultimate multithreat.
