How do you acquire dexterity?
Working as a Tailor (Mona) or Carpenter (Glenda). Unlocked through the perks for these jobs.
in the v0.8.5 working with Mona doesn't give me Dexterity, is it a bug? edit: it is not working in v0.8.6 either
The first job for Mona gives Charisma. The second and third jobs give dexterity, also it's the second job for Glenda.
As I said above, you must unlock the jobs in the passives (perks) section.
