Early on, the game teaches you to hunt wild boars, skin them for their meat, and then craft rations at a campfire. Aside from this segway during the game’s prologue on the beach, it doesn’t delve deeper into the game’s hunting and cooking mechanics. However, you’ll soon learn that health potions prove rather expensive. They’re few and far between for new players, but rations require a quick jaunt into the woods or down to the creek.
Aeternum is loaded with free consumables, should you know where to look. First, find a freshwater source, such as a stream or lake, and step into the water, where you can interact with the surface to scoop up fresh water. Water heals you for 20 health per second for 10 seconds, making it a viable health potion alternative.
Then, of course, you have rations. By hunting boars, wolves, or turkeys, you can retain a steady supply of meat and travel rations that heal and buff you simultaneously.
