I feel like there a problem with the balance of the pages for the book
You could well be right Kevenpaladin, lets look at the current breakdown:
Opening stuff (Contents, Credits, Intro, How to, Quick Start etc.) = 21 pages.
Chapter 1 Epic = 24 pages
Chapter 2 Beyond (What happens after Level 20, New Races, Ability Scores over 30, etc.) = 42 pages.
Chapter 3 Immortality (What is Immortality, Methods of Gaining Divine Power, Divine Realms, Divine Laws, Creating Pantheons, etc.) = 56 pages
Chapter 4 Divinity (Divine Ranks, Divinity Templates, Higher Dimensional Beings etc.) = 48 pages
Chapter 5 Purviews (self explanatory) = 62 pages
Chapter 6 Powers (Divine Boons) = 140 pages
Chapter 7 Magic (epic spells and other stuff) = 54 pages
Chapter 8 Artifacts (self explanatory) = 60 pages but likely 90 when I add the Dimensional Forging)
Appendices (The Omniverse, New Planes, NPCs, glossary, Index) = 47 pages
So 21 + 24 + 42 + 56 + 48 + 62 + 140 + 54 + 90 + 47 = 584 pages
140 / 480 Pages = 29 % of the book ( Divine + Epic Boon ) that almost 30 % that too much Epic Boon are not the most important thing when you play its a bonus after max level, I think just cutting in half the boon content and putting back the Artifacts make more sense.
Well just to clarify, the Epic Boons are only about 10% of the total Boons in the Powers chapter.
If I have 50-60 features and about 6-10 Boons per feature then each feature (Time Manipulation, Crystalline Forms, Regeneration, Force Fields, Creation, etc.) takes up 2 pages. The average boon takes up 17 lines of text which means 3 per column, 6 per page, add in brief intro, a table and that's another column. If there is art (not on every Boon double page spread but a good few) then that is the double page filled.
So the question is what to cut, I don't think people necessarily need 400 Boons, but I am not sure what to leave out. I don't want to have things simply be a sterile number...You gain Regeneration 40 at Tier 2 and Regeneration 600 at Tier 5 and Regeneration 200,000 at Tier 10 (or whatever it is). I'm trying to answer what does [insert power] look like at Tier 5 or Tier 10. I'm trying to make each Boon interesting and exciting. So yes you might get a Passive benefit, but there will also be a Reactive benefit and Lore and some opening Flavour text.
I'll have a 2 page Preview of one of the Chapter 6 Features tomorrow in the next Update.
70 / 480 Pages = 14.5 % of the book ( Divine + Epic Boon ) & 70 / 480 Pages = 14.5 % of the book ( Artifacts )
For the 570 pages part that very big, the biggest 3rd party D&D 5e book I have are 450-480 pages of course im sure there exist bigger but its very rare, the book of Kobold Press ( probably the most famous 3rd party D&D 5e book maker ) they dont really do anything above 450 pages, of course if you consider every single RPG book there was like in the previous message books of 500+ pages but its not common, for example Pathfinder 1e and 2e aside from the Core Rulebook of both none of their dozens of books are above 500 pages and only a few ( less than 5 for now ) are above 400 pages on this its not really a yes or no I would prefer 480 pages but I dont mind 570 pages.
I agree, I think 320 pages is the perfect size for an RPG Book. 480 is something more akin to a Campaign setting book (in my eyes).
I'd rather now the Book was two 300-page books - though off the top of my head not sure I could split it evenly (especially given the size of the Powers/Boons chapter).
Also English is not my first languange so maybe I have the wrong information of the number of pages for the boon or for the book its difficult sometimes to understand clearly.
I think you have it right. Either way no worries my friend. I appreciate the comment and interest. Thank you.
