Does anyone have tips for newbie like me, I died like 3 times by rats and hunger
What helped me in the early game was taking things really slow. try to sneak around and bait the enemies for a backstab using the throw ability a lot of the enemies in this game can be knocked out that way for free damage. If an enemy is not aggroed onto you you should be able to knock them out by hitting them in the back if they are able to be knocked out ofc.
companions are great to hire for some quests if you need a meatshield or firepower.
If you are unsure about a fight it's probably better to not take it or prepare some food and potions or getting gear that might help with the fight.
There should be a pitchfork in a chest in the sewers and that could help you a lot early on you should also find a shortsword in the sewers might be risky but it should be fine if you utilize what you have.
Resting at an inn is generally cheaper than food but you should always have some food in your inventory.
There is no shame in save scumming it is your rpg adventure after all you chose what you want to do and have fun with the game.
The lonarpg mirehaze wiki is a great source of info for most of the general stuff you would want ofc that is if you feel comfortable with spoiling yourself.
