Use rats and goblins to get xp to make early gameplay easy.
Sewer XP farm
When you enter the sewers after starting a new save, you can grind some xp on many stats easy, including but not limited to:
- Light Armor
- Heavy Armor
The idea is simple. Start as a breton. Kill all the rats except for one and let it attack you endlessly while using a healing spell(restoration, armor).
If you start getting low on magicka, either run away(athletics, acrobatics) until it recharges, or use a shield to block(block). You can find a shield and pieces of light and heavy armor throughout the sewer level.
Eventually your shield will break but using a sword to block will accomplish the same goal. You can still gain XP on armor when its broken.
If you get bored of the rat, move onto the goblin(s).
