i think that for now, dont think to many about compoundings. cuz as my theory 1 says :) there r materials that has good and bad effect on base materials. So iron ore + rank 3 fruits is better than iron ore + rank 3 rock :) I think right now just focus on website, forum... maybe some images, and name base materials for items who dont have any yet. If someone know how compoundg work then use any materials with correctly rank. So maybe just use name "rank X fruits, iron" etc.?
