Ok, I was going to go with kobold for the cheese trick, but then I remembered my SS-fu...the Ritual of Association can make you into anything you want from a crunch standpoint : 56,000gp later, and I'm a dragon. Going off a conservative estimate of 20 item creation feats and 10 bardic music feats (and 9 listed perform skills), assume we have 55 feats tallying 253,000gp to play with. As in above and beyond anything from race, class, or level. That's a running total of 309,000gp before buying gear at 20th level, with the usual bottomless gp pool should we need it actually in game, and since we can Dark Chaos shuffle into any Item Creation feat, we can also assume all our gear is self-made. A major bloodline will augment the Tapestry, and the current incarnation of the build I'm toying with is not only built for spamability but also longevity (i.e. never runs out of ammo...EVER).
Wizard 3/War Weaver 5/Incantatrix 3/Hathran 1/Spellguard of Silverymoon 5/Primal Scholar 2/Mindbender 1
The mindbender at the end is probably negotiable, but I really like the utility of telepathy, and at 21 it can always be retrained out when Epic Spellcasting allows us to make Telepathy+Detect Thoughts+Mindsight without a save or SR anyway. The fifth level of SoS gives us CL 20, before bloodline augmentation (52 afterwards), and that bloodline also allows for up to 8 spell levels to be recovered from one action point via Primal Scholar. In short, you have the mana regen of an ES Sorc (D2 reference...). More later, but there he is!
