It does get noticeably different. i was running around at level 20ish whoping everyone that came near me without having to hit and run. Now at level 40, any more than a couple of decent opponants i either have to run and dodge to recharge or use potions.
But the way i changed playing style has chaged the power in battle, now i dont ever turn back! I got my smithing up to 100 and started making dragon armour. i then got enchanting up and with some grand soul gems, whola...
+50 health and +50 magika when i can (when enchantment is 100 you get 2 enchantments per item wiht perk) i think you can put this on jwelery only, so ring and necklace.
reduce destruction magic cost. and some restore magika.
also put some extra carry weight enchanments on boots and gloves.
but this is where the pain comes. dual weild skyforge sword upgraded to legiondary with +30 fire damage on one and +30 shock on the other and both with absorb health (this is wicked as every time i hit i get my heath refilled abit, sory cant remember by how much i think around 20)
and another with soul trap to refill gems when needed.
and they both have around 100 charges each
with the enchantments added i got around 600 magika, 310 healt and about 140 stamina...
Now Everytone in the land of skyrim is fluffed!
People on here that use enchating how comes i cant disasemble certain (powerfull) items like the mages robe, im sure i had the option to do it earlier in the game...?
