The Druid
Druid Changes:
Wild Shape rules excerpt: The form chosen must be that of an animal the druid is familiar with.
Correction: The form chosen must be that of an animal the druid has spent at least 1 hour interacting with, as well as identified via the appropriate knowledge check. Variants (such as a Hydra with extra heads, or the cold subtype) must be learned separately.
Duration Change: Minute/druid level, down from Hour.
Animal Companion Change: The Druid advances its animal companion with a -3 to her druid level to determine the advancement.
Discussion:
On "Wildshape Duration": Now it's a limited duration buff, not an all day form.
On Wildshape Correction: Now cherrypicking will be less rampant in druid forms, returning it to the nature-themed roots and making RP between the druid and the campaign world more important.
On Animal Companions: Much less powerful. Now just another tool in the arsenal of a very flexible class.
