Level 42 now, 100 smithing and enchanting, Made a set of armour with +28 smithing on 4 items, and also drank a +50 smithing potion. Used this to imrpove my daedric set of armour and weapons. This means my armour is over the cap (which is 649 i think?) at about 740, despite only having 3/5 on the first heavy armour perk and not having maching set perk either. Therfore I don't need to put any heavy armour enchantments on the armour and won't need any more heavy armour perks either.
Similarly, I used a +25 enchanting potion to enchant my armour, ring and amulet, though as it only lasted 1 minute I could only do 4 or 5 items before time ran out. Gone for 2 lots of magic resist (28 each) fr and frost elemental resists come out at 42% each, stamina and health fortifys are +70 each (so I've got +140 stamina for 2 peices) magika and restoration on the helm. I've been desperately looking for a another potion so I can do my gloves and axe but haven'y found one yet

. I'm using the spellbreaker shield which is awesome i have to say (creates a ward that stops magic up to 50 points).
It does mean I am now stupidly powerful and hard to damage, previously I was getting owned by mages, but not any more), giants take about 3-5 hits and thalmor soldiers are either 1 hit or 2 (if i land the sprint power attack which also crits, its an instakill most of the time), thats without axe enchantments yet (Stat on the axe says 90 damage, but I still have to put perks in one handed) I'm already on expert but it's still too easy, gonna have to up it to master. FOR GONDOR!!
PS: anyone know if there is a damage cap? I won't put anymore perks into one handed if there's already a cap.
