Main Hand/Off Hand for Crafting.

[Antanias]

I thought I saw another thread on this very subject, but couldn't find it. Anywho, what are the advantages to off-hand tools for crafters? I've been leveling up Blacksmith using leves, but still can't figure out why I would ever need a file.

To make crafting materia...that's all at the moment.
Well and to boost magic craftsmanship if you don't have enough on main hand.

Certain synths have a different end result using main/off if you manage to HQ the synth.

Example:
HQ'ing Electrum Ingot on main hand would result in an Electrum Ingot +1
HQ'ing Electrum Ingot on off hand would result in 2x Electrum Ingot (NQ)

Ah ok, thank you very much

Guess I'll experiement with my tools as I level.

You can easily look it up, if you go to Eorzeapedia, under your target item it will display the recipe. If there is an off-hand result that is different to mainhand, it will display it in the table when you click the "Show" link next to the title "Detailed Results".

It has been standardized in all the new recipes.
Main Hand always gives +1.
Off hand always gives additional yield where applicable and +1 if not.
