The same as in DD, as you do quests and explore new areas. I never did figure out the exact times that they restock. I think it is mostly related to quests you completed. Or major finds such as a new cave or recently killed boss.

If anyone knows how it worked in DD (I randomly checked) then it is how it works here too.

Every time there I run into trouble on the road, there is always a dwarf at the bottom of it. Don't they know how to drive above ground?
