Calligraphy
From Project: Gorgon Wiki
“The art of writing things. Handy for... writing things. It's also a valuable art for swordsmen and other warriors, who can infuse their art with potent additional effects.
Calligraphy is the skill of word craft. It is used by players to empower their Sword skill abilities and write stories that can be deposited into bookcases. One such bookcase can be found in the town of Serbule. Note that a few of these books contain spoilers that other ingenuous players decided to share.
A table is required to use Calligraphy.
Joeh will eventually teach a bunch of Calligraphy Recipes for Combos after completing the Kill Tigers quest.
