Only the gear that is equipped on your arisen has a chance of being dragonforged - not the stuff on your pawn, or in inventory. And even at 3 stars, the probability something will be DF'ed is only 18%, so I wouldn't say most stuff equipped would be DF'ed unless you get extremely lucky.
BTW, as long as the drake isn't at zero HP, (i.e. ready for killing blow) you can run off a little ways and save. The drake's HP won't regen, and if you don't get what you want DF'ed, or anything at all, you can reload and try again. Drake will take 7 to 8 days to respawn.
Ya i killed him like 2 times where nothing got df and only had 2 things at a time df (got my 1* bezal crown df after 2 kills so theres a chance anything equiped that can be upgraded on your arisen to get it my lawn is almost fully decked out in df gear
love the drake most fun ive had fighting monsters besides the cyclopse shooting gallery i found at lvl 10
