I added some stuff; also removed the Diaboli, since they were updated in the Dragon Compendium and are now +1 LA and
imho, not worth it.
edit: Also added some page numbers from Crystalkeep and Dragondex; some of them point to the beginning of the article instead of the actual page, but that can't be helped for now, I guess
FEATS
Truename
Dragon 317 p40
Huge CL and DC bonuses
[...]
Focused Performance
Dragon 338
many cool effects at the cost of extra bardic music
Could you be more specific on the bonuses a "fetish" and a truename bring?
And which cool effects are possible with focused performance? Is this feat worth the prereqs?
Sha'ir
Dragon Compendium
Super cool arcane caster
Not sure whether this merits inclusion. Its domain access is iirc not useful to other classes, and hardly anyone plays one.
Cerebremetamagic feat - puts metamagic costs onto psi powerpoint pool , as in way waayyy more metamagic than usual , (and recharge !)
This is limited by the effective spell level of the metamagicked spell, though. It saves resources if you were going to prepare the spell with that feat anyways, and you have a psionic recharge setup. It's not extraordinarily good, imho.
CerebremetamagicChameleon Crafting feat(s) - put powers or spells onto other side's items , good reason to dip Erudite spell to power 1
Chameleon Crafting sounds interesting, though I wonder whether you need UMD to activate spell-trigger items (what with the "spells" not being on your list). With a little trickery, I guess an Artificer could make use of this in order to be both magical and psionic artificer. Not sure, though.
