HELP!!!!!!!!! I Am a mage. In the party I have a Dwarf Warrior (Cant remember his name) Morrigan, and Leleina. For armies, I have the templars, the elves, and 33 dwarfs. I use the ballista, and I get him to 50%. Then, the darkspawn comes in and floods me. I set up all the three PC's in front of me and the ballista, so they defend me while I fire at the demon. But, the demons always go for me instead of them, and I get overwhelmed and die. I have NO healing potions left. ( :( ) I, myself, are a healer, though. How can I beat it? Are there any stratigies that help? I always get finished off when the darkspawn come. Will they keep coming, or will they eventually stop coming? Thanks!

I have been playing through the game, and somehow I missed the chance to get Wynne to join the party. I was unaware of this, so I played on. Right now I have just killed Loghain, and crowned Allister king. Is it too late to recruit Wynne? If I can still do it, how do I do it, and where do I find her?
