Leveling[]
At the start of a turn, if in the last turn you got enough exp to level, each of your 'villagers' (in the village or in any expedition) level up, gaining 1 or 2 points in 1 skill. This happens after you attract new people/children grow up.
The skill that is improved is chosen separately for each character at random using a formula that looks like this:
70% chance to raise class skill (for my Fat Rat this is Health 31 & Strength 15)
20% chance to raise a learned skill (for my fat rat this is Craft 2, Dexterity 1, Distraction 1, gathering 1, intelligence 2, perception 5, ranged damage 4, shielding 1, stealth 2, will 6)
10% chance to raise any other skill (where for subsequent level-ups it becomes a learned skill)
