I wholeheartedly support your idea of going with 5E for the start and then let the helpful community here make the conversion to 3.5. Would hate for you to feel forced into something you clearly don't want to do (getting back to creating 3.5 statblocks) and eventually prefer to give up on the project altogether than hitting your head against this wall over and over again. I'm convinced people here will not mind if you do it this way, especially if it might get done a lot sooner than the other way around.
Keep us posted how the weekend went then (and maybe a teaser or two about what monsters you worked on?)!
Hello again amigo!
Its not that I don't want to make it 3.5E I just don't think I am still capable. But 5E is SO much simpler it will speed things up (or at the very least not bog things down). I am planning a page in the book that will give brief conversion notes for the monsters into 1st, 3rd and 4th Edition.
First monster I am working on is an Abomination (only one in the book). Its a monster AND a template. Already picked out the poor deity to add the Template to...one of the ones from the partially completed Gods & Monsters pdf, which perfectly complemented this 'thing'.
Entry two I might leave til the end because its ridiculous in multiple ways and might take a bit of extra development time.
The third entry is a Dragon (again only one in the book)...plus a deity that I believe is relevant to this entry and adds a good bit of lore.
Overall the book has 12 entries, 5 of which have 4-5 'independent' monsters (by independent I mean not like the same dragon but different age categories, nor like different sizes of construct, but unique in the way the angels from the Bestiary were unique).
