Work towards making a second set of armour & additional weapons and a shield to facilitate reclaiming your equipment from your tombstone after getting killed https://valheim.fandom.com/wiki/Troll_Set . Keep a chest with your backup gear near your most often used spawn point, and make sure it contains at least 1 of each food type you are currently using. Always try and make the highest level foodstuffs possible and I recommend always having health potions in your inventory, that can also be loaded into your top of screen equipment bar for quick use. Health potions can make the difference between life and death through poisoning, drowning, freezing and when taking extreme amounts of damage from enemies.
