how the hell does a assassin kill a dragon...especially when a dragon just pops out of no where and u cannot sneak up on him. i understand the x30 dual weld owns almost everything but how does one fight a dragon when it pops out of no where and u have to go toe to toe wit itt? any advice?

Use a bow, magic, dragonrend shout (only after mq), sneak attack etc. You shouldn't really restrict yourself to only playing a certain way, the game is not designed like that.

No, the game is designed like that... Just not the dragons.

So listen to everything he said except that last part.

You let the dragon spot you and fire breathe on you for a while till it lands. Try your best to survive that period.

When it lands, take an invisibility potion, sneak close to it, and WHAM SNEAK ATTACK.

i could let shadowmere or licien or however u spell it tank it for me lol

As the others have said just use a bow or wait for it to land. I'd also recommend doing the Night to Remember Daedric quest as soon as it's available at level 14. The artifact you get can help greatly in melee fights with dragons

Shadow warrior perk ftw ;D!

I personally have had no problems killing dragons at all with an assassin build versus them...A good bow, a blade with poison for close encounters, and a good shout should take care of a dragon...Without fail, I have used it before...

What they said, bows and potions and Dragonrend shout should help if you're focused mostly on melee... but then you need to chase after the thing if it lands on the other side of the valley.

I played a dual-wielding in-your-face warrior with light armor. Around lvl20, dragons were too tough for me. I did sneak a little, but hadn't leveled it very high or put perks in it. Still, the dragons were too tough.

Now I am lvl34, I just fought a few dragons, and they were no problem. I guess they were regular dragons. The changes I made:

1) I now often use a shield. Even if you don't block, it gives extra armor. Perk-builds for 2x1h and 1d+shield are very similar. And block can be leveled up easily. Just find a mudcrab and let it hit you.
2) The shield allows me to do a "shield bash". Stunning the dragon for a short while. Do this when the dragon swings his claw at you.
3) Resist is everything. I am a Nord, so I have 50% Frost Resist. I found boots with 40% fire resist. When I fight a dragon, as soon as it breathes on me, and I know whether it is fire or frost, I pop a resist potion. (But only after it landed).
4) While the dragon flies in the air, keep healing yourself. So that when it lands, you are (close to) 100% health.
5) While meleeing the dragon when it is landed, I needed health potions. Nowadays, I don't need those anymore.
6) Use every little trick you have to do extra damage. E.g. apply a poison to your weapon.

I think the resists are the biggest factor. I once had to fight some boss that 1-shotted me repeatedly. He used shock. I went out the dungeon, and got myself 2 pieces of shock resist gear. I hadn't realized I had just found a shield in that same dungeon with 50% shock resist. And I got myself some boots with 40% shock resist. (I have to admit I used the web to find those). I went back with over the cap (85%) resist. And that boss went down like a little child. I think fire and frost resists make just as big a difference against dragons.

If it's on ground you can sneak behind it and cause major damage, possibly even kill it before it gets off the ground.

If it's already on air it will spot you no matter what, and you'll have to run away screaming like a little girl. That's what heroes do

Seriously, have bows with fire and ice enchantments. Fire breathing dragons are weak to ice and vice versa. As an assassin you should have large stamina pool, so sprinting away from the breath attacks should also be easy. stay out of it's attacks and shoot it whenever you get the chance, it takes time, but is very possible. And always keep your distance when it's on ground, they can one hit kill you even from nearly full health.

Sometimes assassins have to use their environment. Kite the dragon to your nearest giant bonfire and wait for it to pick on someone its own size for awhile. Easy enough to land a few strikes on it if you want, but the giants and mammoths will kill it most of the time at lower levels.

Edit: The cat and mouse game of running and hiding behind trees to avoid the gouts of flame while trying to get the dragon to someone who can handle it is rather exciting actually.
