That dragon owned my team at first too. I never even fought that dragon before and didn't help that I was about six levels below it. I made it to the point of where it called in its babies and I was screwed. So...even I get my ass handed to me at times.
Don't forgot collecting all the shards...after all you did say that you wanted to finish EVERY nook and cranny of DA:I.
Doing just that. The shards are actaully rather useful, cause they force you to wander about and find hidden stuff...I donlt even care about the treasure they yield...I find them useful for forcing me to explore.
But the mosaics...I have only finished one and got Gatsi's report (which was cool), but there is a glitch and it shows a piece missing in the wall hanging. I am so pissed about that, and so worked to get the Hissing Wastes one and CANNOT find the last piece! AAAARRRGGG!!!!
I am also bound and determined to recruit every person i can. Did you know you can recruit one of the nobles in Wicked Hearts after you eavesdrop on them? This had made me talk o everyone at least 3 times to make sure if they are recruitable or not....
