I just killed 1 more dragon(a "blood dragon" tougher then the rest of the dragons) 1 mammoth and 1 giant all within seconds from each other lol, i got owned by the dragon easily, so tried a different tactic, he followed me to the verry close by giant camp, there they fought,i kept "shouting" him so he couldn't fly, and when they were all weak, i ran in and started swinging my blade. lol SPOILER ALLERT
Now again this could spoil stuff for some(don't know how or why,but maybe it will, sorry if it does) But the reason I am posting this, is if you go to the place where the dragon(the one I mention above) sleeps, "shearpoint" you get a litle surprise called "krosis", tough for a dead guy. Anyway if you manage to kill him, you get his mask, which gives you a 20% boost on alchemy,archery and lock-picking. AND the rock thing where you get your shouts from gives you a new shout, but 3 levels of it! Not a super cool shout, but comes in handy,the 3 levels of it are Kinda like the push one you first learn.
I attached a screenshot of where the place to go is on the map.
If you allready know this,then good for you, those who don't, this is some good fighting(very strong dragon, and dead guy) and nice rewards.
ps, i don't know how to hide the screenshot so not everyone can see it, so if you feel it will spoil the game in anyway,um...sorry but try not to look
