why dont you turn down the difficulty?
There's always that option, but I started the game on Adept and I've been playing it just fine for many hours. When you level up, it should feel like your character is getting stronger, not weaker. This was one of the biggest complaints with Oblivion and Bethesda have said they fixed it in Skyrim.
This your first TES game? Try it on Apprentice. I'm a TES veteran. I play on Adept just because I don't like the stress of the higher levels. I play more for the adventure and story and just for wandering around.
Oh, there are places you shouldn't go at level 15. Really, there are. I liked to go exploring in Morrowind and Oblivion and see what every pixel of the map looked like. The designers went to the trouble, I want to see it. So I'd go to Daedric ruins where I shouldn't have gone, caves, etc. But I'd find stuff that was really cool too. So I did the same thing in Fallout series, and in Skyrim. I'll find my way over mountain passes, and look for ways to get to the top of mountains that are off the beaten path. This isn't always a good idea especially at level 15, even with Lydia. Trust me. That shortcut isn't always what it seems. It can be the shortcut from hell.
This might be part of the problem. I've explored almost all of the map so I have no idea what parts are supposed to be easy or hard. I played Oblivion quite a bit, but it didn't really matter where you went on the map. Enemies were the same level everywhere.
Last time I got pwned was near Morvunskar as part of "A night to remember". There were some mages dealing shock damage, and they basically one-shot killed me.
You play with one handed and destruction while wearing light armor and complain about taking a lot of damage?
It's called a shield, and if you already use one.. You just don't know what you're doing. Put more leveling bonuses into Health.
I started with Heavy Armor, but found it drained my stamina too quickly and limited how much I could carry. Light armor should be fine, there are some nice perks that get unlocked later but right now it's pretty hard.
Assuming this thread isn't a troll, here's my recommendations:
1) You only need one way to make corpses.
If you're doing sword and destruction magic, you're basically dividing your killing power in half. The effect of that is to hinder your power gain as your level gain exceeds your power gain, and the AI starts seeding enemies far more powerful than yourself. So, if you're having trouble, focus on either Destruction or Swords, but not both.
The idea is that I use firebolts and the like for ranged attacks and then run in with a sword to finish the enemies off. Without ranged combat skills, killing dragons and some enemies becomes hard, especially out in the open.
It was working fine for the first 5-10 levels, but then my fireballs started doing ridiculously little damage. I then found arrows did more damage and started using them instead, but now arrows have also lost their effectiveness. The only weapon that still has any effect whatsoever is my elven war axe, but even that is starting to feel like a toy.
Here are my stats at the moment (just reached level 16).
Two-Handed: 17
One-Handed: 49
Archery: 38
Light Armor: 35
Sneak: 33
Lock picking: 23
Pickpocket: 16
Speech: 30
Alchemy: 22
Illusion: 15
Conjuration: 15
Destruction: 41
Restoration: 26
Alteration: 15
Enchanting: 21
Smithing: 20
Heavy Armor: 25
Block: 30
Magicka: 160
Health: 170
Stamina: 140
The reason Archery is so high is because I was forced to switch from Destruction to archery. It's impossible to kill dragons with fireballs. The fireballs move too slowly to even hit, and when they do, damage is like 5 - 10%. I noticed that at Destruction level 40, you can buy a new type of fire spell, which might work better..
I've been trying to do some alchemy to make health potions, but it's a skill completely unrelated to the stats of your character. It's all about remembering which ingredients do what and where to find them, which doesn't get easier as the skill increases.
