Quickest way for me to reach level 100
1 – Visit the blacksmith in Windhelm and buy all the iron ingots and leather strips he has.
2 – When he runs out of ingots and strips, wait 48 –in-game hours and his inventory will automatically refresh.
3 – If you run out of money, there’s a general goods mechant at a stall nearby you can sell some junk to.
4 – Go to forge and start creating iron daggers. This increase your Smithing level super – fast.
