Hi every one.
I'm just a newbie. :)
I have a question.

If [material A x 1] + [material B x 1] give you "n" EXP for Alchemy skill.

So [material A x 2] + [material B x 2] , I also get 2 things for the result. But is the EXP doubled ?

Thanks a lot :)

no it won't be doubled

when you compound to lvl alchemy you only gain xp by making something higher ranked then of the lowest rank item that was used in the compound.

I just was stupid :D
if [2A] + [2B] give 2n EXP
then [50A] + [50B] give 50n EXP.

But, really, [50A] + [50B] give only n EXP.
I tested.

exactly... although what you said about [2A] + [2B] = 2 EXP it doesn't really... maybe when your alchemy is still low expect to have some jumps of few times EXP than one (I think) but really don't waste a lot of material you compound the best thing to do is [1A] + [1B] the EXP when higher level exp gets so slow...
take mine foe example... (or maybe many others) I had my alchemy superior at 13 (about 46%) It took me maybe (50-100 or more stack to have it level 14) (small wooden gear and took weeks since I can't really click many times a day...) so think about it :)

Hope it helps,
