So what can composition and decomposition do?

Composition lets you combine a number of low quality drops to make a higher quality item (e.g. a number of tough meats can make a tender meat).

Decomposition is the opposite - where you can break down higher quality to change it into lower quality.

You need alchemy stones for this - which you can purchase from the Item Merchant in Elderine with fame.
