when i kill the bad guy at the top of the Battle Tower, the next thing is that i am transormed into dragon form on top of the sentinel island. there i am attacked by somw ballista tower and some kind of nests and i die very easily.
Try to use potions + you shold have some dragon skill points by now(invest them!) + you shold never stand one one place for goodness sake you're a dragon fly and do some cool flying acrobatics!
