Realms of Arkania: Star Trail

To hunt down provisions, you need to make camp while traveling. On the left of the action wheel is an icon for supplies. Select this, and then select a character with the best skills available. They will then hunt for food and water, which makes progress for this achievement.

Note that it’s easiest to do this on easy difficulty, as to can repeatedly send out heroes without breaking down camp. You also always want to choose those with the best skills for hunting. In addition to this, some areas seem to offer more food than others. So it’s worth traveling to a new spot if you’re not having any luck.

It's also worth mentioning that sometimes you can collect more than one provision and sometimes none at all. So you just have to be patient. The higher the skills, the more likely you'll collect more. You don't really need to stress over this achievement overall, because a lot of your time in the game will be for traveling, so you'll be hunting quite a bit.

Once you reach 500 in total (you can check the tracker for progress), head into battle and the achievement will pop.
