There's a guide in the battleon forums about how to get the BLoD in the fastest way possible.
You basically need to start with the Blinding Mace, then Blinding Bow and finally the Blinding Blade.
Mace needs Copper, Bow needs Silver and Blade needs Barium.
Mace quest gives Brilliant Auras and Bow gives Bright Auras while Blade gives Loyal and normal Spirit Orbs.
Once You've unlocked Ultimate Weapon Kit you could just keep repeating it to get you the Orbs/Loyal Orbs/Bright Auras that you need if you haven't gotten the Blinding weapons yet.
All this really means is that you still have a lot of metals to farm so keep doing that daily quest.
