I have recently finished playing through Dragon Age 2 and finally completed and again really enjoyed again, okay a little short, well you guys can check out my review on my blog. However, there was a certain part I was stuck on near the end with lots of enemies, blood mage and pride demon plus all the fade minions. It took me a few times and actually requires you to plan. I have done a video showing my strategy, and using the pause button to plan the attack and defend. Something I just wanted to share you with you guys on how to complete this bit.
It did work so I hope it helps you guys, and any other ideas just let me know.
