Different quality wood

Does anyone know what difference it makes for the different qualities of wood?

Can you put different types of wood? I've never tried, but I would assume not, since Nexon... yeah.. it's Nexon...

Try using the furnace with a stack of normal wood and a stack of carpentry wood. It'll ask you which wood you want to use. Or at least, it should

Is Nexon really thaaaat bright? :c

DevCat programmed the game to work that way. I don't think nexon knows enough about code to mess that up. Higher quality wood is supposed to decrease the success rate.

That is correct. Last time I tried, I think Avg wood decreased success by 2% or 4%, and High Quality wood decreased success by 1% or 2% ~◕Д◕ ^TALK_CONTRIBS2011:01:05:07:27 (Wednesday)

Wouldn't that be an increase..?

You use the old furnace to lower your success rate. Higher quality wood amplifies the effect of whatever you are using the wood for. So it'd amplify the failure.
