would Druid levels stack towards the effective Druid level for your Fast Wild Shape?
The level 5 pun-pun build used the +11 to Wild Shape levels,
without even bothering with the Druid Wild Shape part.
The debate was whether the wild shape ability would work and/or count, without Druid anything.
The good guys won that one
So yeah, (Druid + Divine Minion) level for wildshape.
No idea about Dvati.
