I can’t defeat the mammoth in forests I know it’s supposed to be a boss and I have activated like 5 of those monolith things and still nothing I have been stuck on this for hours
You can also upgrade your weapon and armor at the blacksmith in town, and if you can get the 3 pieces of the sword or the 2 pieces of the staff that will make it easier. If all that doesn't help, it is possible to finish the game without killing it.
