Statblock Spellbook?
 

In Output Hero Statblock, it will show spells prepared for the Arcanist.
Can we get it where it will also print spells in spellbook like the list form for prepared or known spells?

Output Hero Statblock has to match fairly close with what paizo's format is. Are you perhaps asking about the printed character sheet having a spellbook printout or something?

No. I was asking about Hero Statblock which could include the spellbook after Other Gear using the same format as Prepared Spells.

As is, casters that prepare spells and keep spell lists don't know anymore spells than what they have prepared which is a glaring oversight.

Well, statblocks are mostly for NPCs, while character sheets are mostly for PCs... If you have an NPC that you expect to use over and over in multiple encounters, wouldn't a character sheet be more appropriate?

I'm afraid I can't change the output hero statblock as you request, paizo uses it as a basis in their APs and stuff. For the printed sheet, there is already a dossier for spells in spellbook, though I suppose that does lack the "which spells are in which books" feature.

And this is why God created checkboxes -- so that options could be added.

:D
