From publisher blurb:
In this release, there's some loose inspiration from Celtic mythology, as we cover the bard/druid combination.
Bards can become an Ollave, a bardic priest-historian that enjoys an even wider breadth and depth of knowledge and versatility than a normal bard and can eventually tap into the collective memory of all mortalkind to learn new capabilities on demand.
Druids can become an Elder, a wise and mystical guide and mentor who is better than normal at researching rare spells, can become a mystical raven that can visit others in their dreams, and can establish a permanent space for their supernatural research and ceremonies.
And the new Storyteller synergy feat chain allows you to combine any combination of bard and druid levels (not just the archetypes in this product) for a truly versatile and capable supernatural character.
