Friends wanna play valheim again, but last time we played it was really too easy. we want to artificially increase the difficulty by making enemies have more hp/ slightly more damage. However I want to know if there is a way to do this server side (dedicated) so that noone needs to install anything and can just play their vanilla game

Not sure if this helps or not, but the more players the game senses, the harder the enemy difficulty becomes to compensate for additional players...

I do not know the specific command(s) to use (someone else will post it I'm sure), but by using console command, you should be able to make the game think there are more players than there actually are, thereby increasing the enemy difficulty.
