...why no mods until first boss? Because you will have no idea what is being changed, plus you will have little comparision for the difficulty up/down you'll be implementing specifically through the manually set options of Valheim Plus (V+).

You can edit XP gain and loss rates, DPS, food retention and effect, range of crafting and a number of other seemingly minor aspects in V+ that will be meaningless to you until you've done a good few hours, and had to fight the first Boss as intended.

Having said that, bare in mind making the game too easy will really spoil the experience, so be careful of your editing on armour and dps changes (if any).
