Epic robe of dissonance's force boost unfortunately doesn't work with BB. WAI or not, I don't know.
I'm just using it because before I got bracers, it was my perma sup pot 6 item, perma greater sonic resist (fire+elec ship buffs and I have all 5 resists covered even before entering quests), that I slotted with heavy fort (can't really afford removing that can I ?).
I'm eyeing the epic demon scale armor, but I'm not close to making it, and it wouldn't improve the build by much... I'll get it eventually, even if eDQ2 isn't my favorite since she cometfalls.
For the alchemical, I really think flamtouched iron mystical anything/martial water is the way to go. You can get superior *everything* lore by using Rahkir's set + greater arcane lore item (be it skiver, greenblade, noxious fang...), and clickies going up to lvl 8 spells will cover all your needs (except for mass heal which is covered by the flameouched iron shield...)
