Are there any list of what the material do in crafting?
Be careful the bonus depends of the object crafted.
for tools dragon bones are the best handles, but obsidian is my basic choice, for tool'sb lades I usually go with steel, mithril and if plenty or resources adamantine. For fishing tools I go from silk to magic clothes to etheral cloth.
For weapons handles start at iron wood then Ancient Wood , for blades go to steel then mithril then adamantine (obsidian can be chosen too).
For magic staffs I like Magic Wood for my basic model. Ancient Wood for final
For bows Ancient bones then Dragon bones for blades, Iron wood then ancient wood for handles
For advanced armor I really. like the advanced medium armor with air crystal for the evasion stat, chitin is my basic model, dragon leather for the final one
For advanced weapons I try to choose between air or or cold or fire, depending of classes.
For heavy armor I try to choose Adamantium on one piece (chest or legs) and mithril on the other. For crystals it depends of the mood, Air is a solid choice, I tend to lack of Earth Crystals but Fire and Cold are good to
