Vanilla Chapter 2:
Spend Knowledge Points: Press O to open the Feat screen. There you can see new types of knowledge which you can unlock. Learn a feat to gain access to crafting recipes which can then be accessed in your inventory, or in the workstation that is required to craft the object.
Get a dedicated weapon: Weapons can be crafted or looted from fallen enemies. Just remember to keep them in good repair. Nothing worse than a weapon that breaks mid-battle.
Eat a filling meal: Cooking food requires a campfire and the raw ingredients. Eating raw meat is a bad idea!
Find shelter: Shelter can be created through building or found in various locations in the world.
Perform a Heavy Finisher with a weapon: Combine light attacks and heavy attacks in a combo that finishes with a heavy finisher.
Use a Torch: Craft or find a torch and equip it. Torches can be held in the off hand, freeing the main hand for tools and weapons.
Scout an Exile Camp: You can find other people near water sources or easily defended locations
Store goods: Place items in a storage container to keep them safe. Open the radial menu to lock and unlock the box for other people.
Create a home: Place out foundations and walls to create a base. You can place building pieces by equipping them to the hotbar then selecting them. Of course, you might need to craft them first.
Block an attack: Equip a shield and use it to stagger an enemy in combat by blocking their attacks. Shields are useful, but they lose durability quickly and can be destroyed mid battle.
