Realmshelp has virtually every single one of them posted online. All you have to do is come up with some theme appropriate Spells for the Great Wyrm and copypasta the list removing the ones the younger age groups don't have access to.
Arigato Soro Sempai!
Eerr, sorry, been watching a bit too much anime today. But that's definetely gonna save me a LOT of boring writing, so thanks again.
Once Ols gets going, you should see a trend in the items coming form the same optimized choice pool. As part of providing semi-generic and theme fitting dragons,you'll see them picking up the same relative immunities as he goes. It's the same set up you see your PCs with really. Except as a PC you may have been side tracked by stuff that increases your Turns per day, or your Smite Evil, Favored Enemy, Sneak Attack, etc. TDs lacking that, will primarily deviate for their color coded themes and weaknesses, that's about it.
Well, one of the nice aspects about dragons is that you can specialize them for different stuff. Heck, you kinda have to considering they have sorceror spellcasting and thus can't go changing their spell list daily. I plan to have each color be focused on a certain strategy that's thematic for them, and later on go about specific feat/spell/item combos on the other guide sections.
Mostly that they're the best spellcasters, largest, and all around have the most stat bloat.
Lolwhut?
Dragons are quite lagging behind in spellcasting. There are monsters out there that are actually fullcasters, and they have even more bloated mental scores than dragons. There are even monsters that have faster spellcasting progression than fullcasters of the same CR.
They're also lagging behind in size. Most dragons don't actually ever get colossal, and those who do so only achieve it over epic levels. Heck, several dragons start small if not tiny sized.
Gold Dragons are marginally stronger. (What I can't get my head around is why all the metallic dragons are comparatively better than the chromatic dragons).
Altough wotc never directly says it, the reason for that is because the forces of evil are simply much more numerous. One of the sample gold wyrms is precisely described as being unable to deal with new red dragons faster than they're being hatched by his enemies. Same for outsiders, a Solar can wipe out the floor with a Balor. But there's infinite amount of Balors out there, and a finite number of Solars. And then there's also Pit Fiends and Tarrasques and plenty of other evil CR 20 enemies ready to wreck havoc.
