I'm feelin it too. Really strong across the board for what you want from a bard with Perform (I think sing is perfect), Bluff, Intimidate and Diplomacy. Great Sleight of Hand when you need it. Arcane Duelist should be a fun Archetype to play with. What's the overall AC?

You can get really creative with Dungeoneering if your GM allows it. Like which way would likely be the exit, or how to cave in the ceiling to trap any pursuers behind us (natural 1 to cave it in on us and we all die )
