From Crea Wiki
Characters have talents (default 'T') that represent the character's proficiency in a field. Currently, there are five talents. Arms, Syle, Gather, Craft, and Explore. By performing actions related to the talent your character will occasionally gain talent points. For example by crafting items or learning new recipes you may gain TP for your Craft talent or hitting a monster with magic may yield TP for the Magic talent.
