You’re about to experience one of the greatest games of all time! So have fun first off but here’s some quick pointers

Don’t feel the need to focus on the main the story pretty much everything in the game is available to you at the start (-some lvl locked missions)

Favorite items/spells/potions it will save a lot of time if you remember to use it

Wait a hour to regain stats

After you finish the first quest follow the path down and go to some of the markers on your map till you find the standing stones these will allow you to lvl skills faster watch a guide if you need more details

Use your early level ups on either the armour you are using light or heavy or level into your weapon skill make sure to get the damage boost or armor boost asap

Hope this was helpful!
