The dungeons of the Black Magus Sorven of the Seven Lights' mountain keep are ripe for plunder, brave adventurer. Perhaps you will find the stairs to the howling tower that rises ‘neath the ternion moons.

Leveling Changes
Each Party member receives the full XP total per session.
PCs may level multiple times until they hit Level 3.
After hitting Level 3, they may only level once per session, ending 1 XP shy of the next level if they over-level and spend 250gp per level to get the benefits of that level.
PCs may freely collect XP even if they have level-ups waiting.
- Ex: A Level 4 PC can collect XP to reach Levels 5, 6, 7, 8, etc., even if they are still only Level 4. They will have to spend 1d4 weeks, and the GP cost PER EACH level up to progress.
Leveled Hirelings and other followers who gain XP take a share from the Party Member who hired them.
