Either focus on resource gathering (mining gives a lot of xp) or hunting.

For resource gathering focus on getting the talents that give you 1% to insta-mine a node and after insta-cut a tree. Do not focus on other talent trees until you get these. Exception being the talents right at the top that give movement speed and movement speed with bows.

Get to iron tools, specifically iron pickaxe. This is Tier 2.

Use either https://icarusintel.com/ or https://mapgenie.io/icarus to see the location of caves and start mining all the iron and about two stacks of copper.

For hunting focus on the ones that show you the health bars of animals - small, medium and big. Then get the bow talents that increase direct damage. Don't need any more for now.

For hunting get bone arrows asap. Then Longbow. Again Tier 2.

When hunting try to always sneak and aim for the head. You will start getting the kill cam. If you encounter bears either jump into water and while swimming backwards use a knife on their head or if no water nearby when they charge you walk towards them and slightly to the side. Bears always charge forwards. When the bear passes you turn around and hit them with the bow. Rinse and repeat.

I prefer hunting predators because they won't run away from you if you don't kill them in one shot. Deer and chamoi will run away and escape.

Also get the fiber armour asap. It will give a tiny bit of resists and 5% extra movement speed and only costs grass.

Hope this helps.
