Well im trying to re-complete my Skyrim achievement, because of dawnguard, and I need to kill a legendary dragon, so does anyone know the minimum level for one to appear?

70 i beleive, which is crazy

I have some serious levelling to do then...

Is it even based on level? Been playing my level 81 and still only encountering Ancient Dragons.

supa rare

im at lvl 78 and since downloading dawnguard i havent seen anything higher than blood dragons. prior to the dlc i found ancients everywhere...
