THANK YOU, THANK YOU gm2501gian for telling me about the composing manual (and everyone else who offered advice on composing). I didn't think anyone would bother to answer!
Is there anywhere that explains how to compose with what crystals to get what you specifically want? I haven't been successful even trying different things to combine small potions to get larger potions. Also, I don't understand "drop rate" and when a weapon says +2, etc. I need to get stronger to fight the more difficult enemies. Can anyone offer assistance?
