Does anyone know the mechanics for spiritbonding new crafting gear while fighting mobs? Please don't guess. We all know we can't convert tier 5 craft/gather materia yet. Here is what I tried:

Bought NPC crafting gear at Moghome equippable at lv55. Fought mobs in overworld Lv 50,52,54,56, I don't recall exact levels but I tried a range. Stuck at 1% spiritbond (no gain).

Can anyone confirm what mobs in which area/dungeon must be fought to spiritbond this gear (or any new crafting gear), and confirm conversion rates to tier 2/3/4 crafting materia? It DOES spiritbond just fine when crafting, but that's expensive to consume so many new mats. And to gather that many mats yourself is too time consuming to do just for spiritbonding.

FYI, spiritbonding iLv 45-50 gear in Urth's Fount still works for getting tier 3 materia ~90% of the time and tier 4 materia ~10% of the time (for iLv 45-49). I was just hoping that there is a new, better way, with the new gear.
