I made a set of crafting accessories to spiritbond:

Holy Cedar Ring (x2) = Level 52 iLevel 70
Yeti Fang Earrings = Level 52 iLevel 70
Holy Cedar Armillae = Level 53 iLevel 80
Holy Cedar Necklace = Level 54 iLevel 90
Holy Rainbow Apron = Level 54 iLevel 90

I can't freakin find out what mobs increase spiritbonding progress on these items. I tried: Level 59 mobs, Level 54-56 mobs, Level 50-52 mobs (HW mobs), Level 48-50 mobs (ARR), and level 50 dungeon mobs (Castrum Meridianum). All items are still at 1% bond that it defaults to when first used, and for each test I killed about 10 mobs.

Please please don't tell me that we can't spiritbond HW crafting accessories through battle...
