The Excelgraph literally has an engine built into it. It follows in line with the other tomes. All I can say to your "b-BUT MY TOMES" is wait until next update where Dev makes a few changes. It'll get better, but I don't like the idea of a mage who has 20 strength, if that, should be able to wield a rustic carapace magical moon and a excel graph in your offhand.

This creation has made Galdric, Floating, and the 'lighter' ores more of a viable option. Creating items has always been a bane of the system, and next-to-useless when crafting anything but very specific ( Wo-Dao ) weapons.
