In Genesys, there are a number of skills you can use to do stuff. We're gonna talk about the skills we are using in this game here! A more thorough description of what the skills we're using do is in the Genesys Core Rulebook, on page 52.
Combat skills are used to make combat checks; you'll be using these to attack.
Knowledge skills are used to figure out what your character knows.
Magic Skills are used to cast spells (see page 210 of the Genesys Core Rulebook). Arcane, Primal, and Divine magics are as in the Genesys Core Rulebook, and Verse is like bardic magic.
Social skills are used to interact with other characters.
General skills are used to do the vast majority of actions outside of combat.
