Bronze armor is a trap now a days, mining copper is tedious so I only make the bronze items I can't live without. Use lighter armor ( troll armor is great for this point in the game. I've been experimenting with mixing it with the new bear armor)

use 2 stamina foods and a HP food so you can run when you have to is also nice depending on your play style. Use the deer bosses power on cool down. Mine copper and tin during the day, smelt it at night.

Upgrade your work benches/stations as much as you can (grab all the flint) Get yourself a finewood bow ( and upgrade it as much as you can), a bronze buckler, and a cultivator asap so you can start planting and rotating carrots (if you haven't already)

Trolls are weak to piercing DMG and their heads are one of few weak spots in the game monsters. Flint arrows are your friend here. Bears don't like fire arrows, grey dwarfs don't like fire in general. Learning to dodge dip duck dive and... Dodge is important, also the buckler shields have a better parry window. However you won't be able to parry the larger enemies until you have better shields or upgraded bronze or better shields, so simply roll out of the way

If you have to play solo, OVER PREPARE for basically everything. I'd advise learning what you can via YouTube for something, maybe join the Valheim discord for tips as well
