What happens if we pump it up to Brutal 4? Does the world explode or something?
You divide by 0. You can never do any damage, just reroll constantly.
I'm just guessing that this'll be fixed with errata, but since Orb
still hasn't gotten smacked with common sense yet, who knows.
That's why you need the goddamn Vadalis Griffonmaster paragon path (Eberron Player's guide, page 79). Why? Well, a couple of reasons. One is because it flies and scales to your level, which should be good enough. But the big reason is so that the griffon has the mount keyword. Which means that you can back that ass up with some Impentrable Barding (Adventurer's Vault, page 123), which gives your mount resistance of your level, no greater than 10 per tier, which means that your mount has 24 resistance. And will have 256 hit points. And then you redirect every effect to your mount and dance around the battlefield.
I remember there being a similar option with one of the Draconomicon's mount dragons and some obscure Adventurer's Vault item.
The entire thing has been successfully subjected to Blandification, thereby rendering it boring. All of it includes the broken parts.
The only good thing about it is they at least tried to do something different, which makes them a notch above Pathfinder and their ilk.
I don't find it bland or boring, and many agree with me. 3.5 was something that quickly became boring for me, let alone 1e, 2e, and especially 3e. I haven't looked at Pathfinder so no comment, though it's based on 3.5 so it's bound to suck.
Fun is subjective, but having to dumpster dive through over 9000 books just to make a good non-caster is a real hassle. 4e is starting to take this route as well, of course, which just solidifies that dnd as a whole is fucking shit.
