So Josph and Harley have spent the last year making minor tweaks and formatting the final product? I find that hard to believe.
Don't the final rules go to level 10?
Isn't corruption significantly toned down?
What's the action die progression over 10 levels?
I know you are trying to be helpful but it is too close to the actual release to play beta now.
I kind of want to stay on topic. But I'll touch on some of these questions. "Minor tweaks" would be inaccurate. There are way more spells, 5 complete patrons and their spells, and lots of clarifications. Those alone fill half the book and weren't in the Beta. A lot the material are for Judges, so players might feel like they're only getting more spells. Which is true, there aren't any new, or additional, "rules" for players. Game plays the same, combat is essentially "the same" as the Beta. But for Judges, there are tons of new things, tips for running adventures, awarding treasure and creating encounters, which in turn gives players more things to do, and reasons to do things. "Formatting" is not easy, as a graphic designer, I know that presenting information, but creating tone and including appropriate art is not an easy thing to do.
Yes, characters go to 10. But isn't that common knowledge? Corruption is toned down a little apparently, from my perspective as the Judge, I can't really tell. The old wizard in the party (who's dead now, but lives on as a Patron in Crawl! No.1) got pretty corrupted quickly, but he was way more aggressive with his spells than the new wizard (and the elf.) So I can't really tell. I can tell that misfires happen a bit more than corruption, so I guess yes, considering misfires don't have the long term effects of Corruption. Action dice? The additional action die you get at 5th keeps going up as you'd imagine. A 10th-level warrior has 3 action dice, the third being a d14. You can extrapolate other class's from that. The warrior's Crit Die is 2d20 at 10th.
re: playing Beta, nope not too late. As I said in my last post, converting or switching from Beta to Final is really minor. It's not like the difference from the 4e RedBox to the 4e Full rules (ugh, don't get me started...) Beta characters are not stunted in anyway, they're identical for the most part, especially up to 5th-level. I haven't stared at the rules enough to notice the major differences, a +1 here and there. Where a saving throw is +2 at 5th, it's probably +4 at 10th.
