In L5RRPG, school curricula always list relevant Skill Groups and individual Skills. How does purchasing a Skill Group differ from purchasing a Skill? In purchasing a Skill Group are you purchasing +1 Rank in ALL of the Skills in that Group, or just one Skill in that Group? Or does it work in a different way entirely?
Skill Groups vs. Skills
Your curriculum is telling you what you can purchase to get full XP credit for Rank advancement. If it lists the school group then spending XP on any of the skills in that group counts. Spending the XP still follows the normal rules, which is one skill at a time.
Thank you.
