So I'm level 40 with Two Handed, and Heavy Armor resting comfortable at 100
How am I supposed to get to 50, within a reasonable timeframe?
Sneaking around whiterun for 3 hours for 2 levels of sneak, or putting on light armor and letting wolves eat me for 20 minutes doesn't sound too exciting
Any ideas?
Put on light armor, and use nearly harmless spells repeatedly on weakish enemies, I suppose.
Basically, you're asking for a way to do tedious grinding without the tedious grinding, so I can't really offer up much by way of solution, other than using your trainers and doing silly things like spamming telekinesis or just letting things gnaw on your shins for a while.
If you haven't done it yet, you can probably use your crafting skills, as well, as if you have the money to buy lots of ingredients at end-game, you should be able to pound through large quantities of the stuff in short order.
