Awarding XP
Award the players 1 XP for each significant, interesting thing they did. It’s simplest to award XP for completed challenges, but you may also grant additional XP for things they did outside of challenges, at your discretion.
Awarding 3 to 5 XP per session is reasonable for most groups. Less if you want slower-paced character advancement. More if you want a short, fast-paced campaign.
Awarding Treasure
At the end of every significant and appropriate challenge, award each player 1 or 2 Treasure. Work with your group to determine which type of challenges should award treasure. Looting Dungeons? Negotiating Treaties? Performing a service for a local Lord?
Be aware of any characters who have traits which rely on treasure as a resource. If the characters need treasure to function, make sure the treasure flows.
