if svamp is too hard for you then you are too weak when it comes to skills.
valheim is a very easy game to play. you just cant rush things.
you can kill everything in svamp with a bow. if you choose to have more of a challenge (like I did once and beat the whole game without ever using a bow)
you can use a sword or whatever.
learn when to swing the sword and when to run away etc.
level up your skills also, if you can low skills, then you will be weaker.
this game isn't fun when rushing, take your time, stack up items and food and build your base.
then move into svamp.
good luck
