First let me say, I love the Priest of Volwryn.
And here's a batch of requests, since you guys insist:
First request is for the Bard. I recently noticed bards are seriously lacking representation on one form or Art: the plastic arts. There are some 3pp Artisan classes that cover things like metalworkers and leatherworkers, even tailors and jewelers, and a nifty one for photographers by Purple Duck, but there's nothing that really does painters and sculptors. I believe this could be done as two archetypes, one for painters and one for sculptors, though both would need trading some spells from the bard list for more appropriate spells.
Instead of Bardic Performances, maybe the Sculptor could make small sculptures while preparing spells, that act as Summon Monster spells, except he has to choose his monsters when he prepares spells but could add some things like simple templates or evolution points. Throw in some Versatile Crafting instead of Versatile Performance, extra damage against objects/constructs and some other minor abilities.
For the painter he could also do some spell-like Summons by quickly sketchin the monsters in special paper, like Sai from Naruto, but maybe he culd have the ability to 'paint' the world, creating illusions, paint landscape so realistic they become portals, or paint colors on people to affect them with emotions, like that one One Piece villain. And of course their own version of Versatile Crafting (painting) at second level.
Now that I'm writing it down it occurs to me, both these archetypes could also be made as Summoner archetypes with a construct eidolon instead of outsider for the sculptor, his Galatea masterpiece, and a Lesser Eidolon, like the Master Summoner archetype, made of ink and turned into a painting while unsummoned, for the painter in exchange for the portal and illusion stuff.
Another unfilled niche for the bard is writers, but I don't know what could be done with it.
Now ideas for the Generational Hero:
First I was thinking on ideas for the Generational Hero based on the idea that he was part of a lineage of heroes (like the Belmont family, or the Phantom) or a reincarnating cycle of heroes always fighting the same evil (like Link, or Buffy). Then I reread the fluff. Oops.
An idea I had was of a Generational Hero who got part of the memories from his ancestors/former incarnations, either naturally or through an item where his ancestors deposited those memories. It could get some bonus on Knowledge checks, the ability to consult their experience for bonuses on skill checks, and maybe other abilities.
I also suggest archetypes for the Generational Hero that involve time powers (Hero of Time), light abilities, maybe a Kinetic Blast (Hero of Light), and shapeshifitng into one particular animal (Twilight Hero).
A new idea would be a Gen Hero who is much more tied to his prophecy, to the point that he is much easier to revive because he can't die until the prophecy is fulfilled, or he can declare one enemy to be fated to die giving him a curse that weakens his defensive abilities. Maybe instead of a Generational Bond he could choose a Fated Companion or Object that is mentioned in the prophecy.
Also an idea I had for the Gamer, is that the Gamer comes back unmoored from Fate, outside the wheel of karma and the loom of fate. That could grant them a permanent Nondetection spell or other ways to fool divination spells, like the ability to alter his auras when he changes his Build, like he is LG Human but he can instead appear as CE Undead to Detect spells to fool enemies; the ability to alter fate by forcing others to rerolls when someone rolls a natural one or twenty, or healing people but only when when they drop below zero HP, maybe they can a different way to Change Fate depending on their current Build. Like, the Healer can change the fate of people who were supposed to dies healing them as a free action when they would be reduced to negatives and the Tank can change the outcome of fights by forcing the enemie to reroll when he gets natural twenties and allowing allies to reroll when they roll natural ones.
