This guide will let you know how to get the Flint in Valheim. Go through the guide and follow the simple steps to get Flint.
The first you will need to do is head across the river, and you will find a lot of Flint near the river, as shown in the image below.
When you find it, you have to activate it and then take it with you. You can easily find these flints near any water source, so you have to look around the whole area, get as many flints as you want, and then bring them back to your base.
