Looked at the system and had a few questions in addition to those I've read in the thread so far.
1 - how many points are awarded for a level?
2 - can you spend points in all 6 planes simultaneously?
3 - to unlock adjacent hexes, do you need to purchase 1 rank, or all ranks?
4 - clerics get masteries for every weapon they can use except warhammers. Is there any reason for this?
