Alchemy and smithing I'm fine levelling up. Both have been unbearably easy, even if alchemy takes a considerable amount more time.
But enchanting. Best I've been able to do so far is go out and kill a bandit, filling the Black Star, then enchanting one of my many daggers to get a skill up. There has to be a faster way though. This would take AGES to finish at this rate. Or I might run out of bandits.
Advice on Enchanting Power Levelling? I'm desperate.
I finally caved and made a Breton =p
Find the following enchants from blacksmiths: absorb health, paralyze or banish. Absorb health is rare, but nowhere as insane as paralyze or banish. I've noticed that Niranye (Thieves Guild fence in Windhelm, she has a small shop across the blacksmith) commonly has paralyze bows in her inventory.
I hope you still have your 300~500 iron daggers - if you don't just repeat the same process of buying iron ingots + leather to make your own iron daggers. Camp at College of Winterhold, there are 4 tutor mages that sell petty filled soul gems. Clear them out, enchant your iron daggers and sell them. If you have banish, then the process is much faster as you can buy petty and lesser filled soul gems and still make a profit. If money is not a concern and you're willing to make a loss, go ahead and buy greater filled soul gems as well. I do think that it works the same as alchemy, in the sense that the greater value the enchantment the faster it levels. Falion at Morthal and the mage at Dragonreach are also easily accessible mages, but you have to deal with loading screens and you only have access to one mage at a time. Still it beats staring at the screen while waiting for 48 hours to pass.
The same bonuses apply, so check that you have Mages Stone equipped, and Well Rested bonus to give +30% to leveling enchanting.
