I'm about level 12 and apart from that first dragon I have not managed to even knock a dragons health down one third of the way!
I solo'd my 1st dragon when I exited BFB & it spotted me. Ran to a nearby cave & hid from it's flames.
Bow combat until it was low then ran down to water & survived some roasting as I plunged arrow after arrow in him repeatedly, so I could see where he flew to die.
Took forever but they are relatively stupid if you have a decent shelter.
He COULD have landed at entry to cave & roasted me easily.
But he didn't so it was easier than I thought - just a lot of waiting to get off each 1-2 shots took 2 hours overall, 95% waiting.
Get to any doorway with an open space behind it, he will show up & flame but will take off when you damage him.
Rinse/repeat = dead dragon, at least until I get more skills.
I was level 9 or 10.
I use this weakness in the game all the time to toy with multiple critters in dungeons. Go into any space too small to hold you both & even casters will not fire IF you are out of line-of-sight quickly.
Then I fire away at my leisure while they glower at me.
Hope they fix that soon but it IS riotous to watch them!!!!!!!!
My rogue can clear 4 or 5 out of a room quickly but WTH sometimes it's just too easy to play with the AI like this.
ENJOY>
