No. you can have the egg (from valencia's chain quest " eggxactly five") you can also use your baby dragon as a pet, but if you want to Grow your dragon and do titan battles you need DA. Even though....
no you just have to talk to robina and click quad force and press search and she will tell you where to find the difirent piece (they are all in diffrent places)
no just go robina and talk then...
