i need some moghancement clarification

[Retsujo]

It all depends on which Moghancement you want. Each furnishing gives their own. Look into Moghancements for the great scheme behind it all, but in order to get the skill from having them in your house, you have to have the specific Moghancement they carry. Every furnishing has their own Moghancement, and the determining Moghnancement that sticks depends both on the element most potent across all furnishings, and the furnishing with the most potency in that element.

The 50k GP item will only carry a simple Moghancement that will only really boost success rate or lessen materials lost. Combining the 150k and 200k items will give you a "Moglification" in that craft instead of a Moghancement. That is a +1 to your skill. The Stall will give you the "Mega Moglification" which starts out at +2. When you place either the 150k or 200k item in combination with that, it will become a Mega Moglification +3 towards your craft. And then when the 200k, 150k, and Stall are all combined together, you get a Mega Moglification with +5 towards your craft. The 50k furnishing has no enhancement towards the Mega Moglification's skill.

Though there is an added effect when you have all three furnishings put together, whether it be a higher success rate or a lessen in items lost. I'm not sure because I'm a fisherman and the additional effect there is less time between casting your line and feeling a bite. Some rumors say that the 50k item enhances the hidden effect a little bit, but there hasn't been any proof. Of course it's harder to prove something like that than it is to test a flat out increase in skill.

EDIT: I think Advanced Support is +3, so that would make it +8 towards your craft. Add in the Smock, other GP equip, and the new items from gold chests, and you can get quite a boost!
