So, i really like my thief character, lovely time. I laugh, i tense up when enemies are right beside me while i am in sneak mode, it never gets old for my Khaijt thief. But i have a single problem!:
How am i suppost to kill dragons effectively?! I seem to always die whem fighting dragons. I can't sneak attack them, i cant pickpocket poisons onto them, its almost useless to fight them.
Do any experienced thieves know the key to killing a dragon? Especially during the main questline!

First off flying dragons are very good at spotting stuff but if you go into sneak mode then you hear it will rarely find you.
However doing sneak attacks are pretty hopeless unless you can shoot it while fighting other far away.
This is also the way you kill them, wait until they engage other targets then attack note the other targets might be bandits or powerful animals like cave bears.
You can use potions and enchants to protect you well against the breathing attacks, and you can always sprint away from it.
