From publisher blurb:
Within Inspired by Heraldry...
We bring you 5 new unusual creatures for Pathfinder that are often featured as decorations upon a shield of arms: biscoine, enfield, lepus hositili (murder bunny), talbot hound, and yale.
We also introduce heraldic feats that allow characters to draw power from their noble bloodline, familial history, and the spiritual patron of their clan. We feature the following patrons: allocamelus, basilisk, bear, biscoine, boar, bull, dragon, enfield, griffin, lepus hostili, manticore, phoenix, serpent, talbot hound, toad, unicorn, and yale.
And we finish Inspired by Heraldry with the heraldic knight, an alternate class for the cavalier that invokes the power of their family's crest.
