Exploration General Move Concentrate
You’ve mastered the art of magic on the move. When you use the exploration activity repeat a spell, you move at full speed and are not fatigued by casting the spell every turn. You must rest for 10 minutes of out of every hour. You can instead sustain a spell up to its full duration as you move at full speed instead.
