I love decorating my MH, and I need ice energy for leather moghancement, so I'd love a Buckler Plaque.
From Somepage:
# Main Skill: Goldsmithing (94 - Veteran)
* Sub-Skills: Woodworking (? - Unknown), Clothcraft (? - Unknown)
* Crystal: Fire
* Ingredients: Mythril Ingot, Silver Sheet, Mahogany Lumber, Platinum Ingot, Platinum Sheet, Fluorite x2, Rainbow Velvet
As I understood it, you just looked at the items from the subcraft to get a rough idea of the subcraft's level requirements. So for Buckler Plaques, woodworking's subcraft would be roughly Mahogany Lumber's level (~51). The problem with this is the cloth requirement: Rainbow Velvet is level 79 cloth.
I really hope someone's going to tell me I figure subcraft levels wrong, not that this item is funky and requires a crafter who is high 80s gold, 70s cloth. :/
