Repairing items -- Cost 1 of each of the base materials to perform. Damage level doesn't matter. Very efficient
Build structures out of wood -- learn the mechanics with easy to get materials
Loot -- check everything, even if it seems empty it may have money and looting a chain shirt is way faster than mining 300 iron
Craft -- you can craft on the move, be making thread/cloth/bandages all the time
Disassembly -- Figure out what items can be disassembled/crafted into lower weight items
Crafting -- you can run stations simultaneously
Marigold -- Cures poison, makes HP pots Marigold is the vegetation of the future!
Combat -- have a shield, hold RMB to block, keep food/water above 90% to regenerate health quickly, bandage if you start to bleed, attack after you block
Gear -- a lot of stuff can be found in abandoned villages. Reinforced axe is the go to item for harvesting, and is a decent combat weapon.
Carrying stuff -- make a leather backpack and leather bag. The backpack requires a table
Hunting -- Make a bow (sticks, thread, leather straps) at a crafting table. Arrows are easy. Don't chase rabbits!
Wolves -- My nemesis. Don't run around naked. See my combat tip
Armor -- max armor is 90 atm. See gear tip. Max armor is chain/heavy chest, armored boots, goggled helm, gloves, vambraces.
