Hi,
As I read the Dancing property, it _seems_ as if the ability sucks. It seems to be a bit worse than a "spiritual weapon"--a 2nd level spell.
As I read it, the weapon just gets your BAB and it's magical bonus--no strength, no feats. So at 5th level a fighter with a +1 dancing longsword would have a +6 attack and would do d8+1 damage. You have to send an action to get it started.
By level 11 we are talking about +12/+6/+1 which, against an AC of 24 (typical for a CR 11 creature) you are going to be doing around 3 points of damage a round. That seems a lot worse than having a +5 sword.
Questions:
A) Am I missing something?
B) Does it attack the first round it starts dancing?
