I have weapons that do up to 235 damage. Yet it is still difficult to kill enemies on Adept difficulty[ Sorry this is my first TES, need to learn the ropes

]
For people who manage to make it on Master, how much damage does your weapon hits? How much health do you have? What is your armor rating?
Fighting Ancient Dragons is so difficult, becuase when they use the firebreath shout I lose like half my health.... I would appreciate some tips, because I wanna try master difficulty

Yes, I only have trouble when going against Dragons and Mages, everything else is quite simple. So yea I might think of adding some fire resistance and stuff. Although I use so much One-Handed enchantments so I don't really know where I should put it. I might put it on my Body armor(The only armor that is not enchanted).
This is my armor set:
Daedric Helmet-Bows do 35% more damage
Daedric Gauntlets:One haned do 40% more damage
Daedric Boots:One Handed do 40% more damage
Daedric body armor: Nothing yet.
Silver Necklace:One handed do 40% more damage
Silver Ring: One handed do 40% more damage
That is basically it, although I can get one of those crown things and enchant them right?
Basically more magic resist is needed which can be acomplished in several ways.
You can enchant Necklace/Ring/Shield with + magic resist. You can perk into Alteration. You can use the Lord Stone.
There's a quest that gives 15% magic resist and finally, Bretons have 25% magic resist as a racial.
If you get the last perk in Enchanting (Extra Effect) you can put 2 enchantments on 1 piece of gear so you
dont sacrifice damage for resists (e.g. your necklace could have +magic resist and +onehanded damage).
You also have the option of using + all magic resist along with individual reists (e.g. +40% fire resist).
I explained all of that in http://www.gamesas.com/topic/1331669-enchanting-armor/.
In short: the most you can pull out of this game magic-defense wise is a 97.75% reduction (not counting Atronach birthsign or perk).
As far as armor ragin goes 567 is the cap (in terms of % damage reduction), but you can go much higher than that although its useless. 567 armor rating or 2000 armor rating is all the same.
Your weapon could use a bit of work imo, my warrior's deadric sword has over 500 damage with 97 in One-handed and all the relevant perks.
