I'm having problems with the first area. I go through the portal and then meet with the new party member. Then through the door the left. The room fills with those bat things. I used most characters to kills the bat things and had my theif open some of the chest and get the keys but can't get out. I suppose in need the keys to turn off the bat portals. But how. I know this is going to be easy after your help. Thanks

You should be able to see the Red ring inside the domes. Just have your parites attack those. Once they are all destroyed the Meffits will go away.

And then those locked doors can be accessible
