You can quite safely ignore the skill system entirely.

If your playing normally (i.e. not spending hundreds of hours grinding specific skills) you'll float between 30-60 for your active skills and 10-30 for your seldom used ones as you level up and die repeatedly in new biomes. Skills softcap around 60-70 for normal gameplay as thats where the 5% penalty for dying outweighs the gains from living.

There is a large difference beween 0 and 100 in a skill (about 40% stamina/etir drain) but the difference between your practical skill levels is close to 10%, which is why i say worrying about them doesnt matter much.

Every time you switch to a new weapon type for a new biomes set of weapons, your old weapon skill will gradually descent back to mediocre. By the time i reached the end of mistlands my Chopping skill was at 23 for example, even though i've felled literal forests.
