After a long gap I'm trying Origins again. Because its been a long time I've lost authorizations for all the freebie stuff (Battledress of the Provocateur, 300gold mace etc) which makes it tougher but I breezed through Nightmare with a full party. I'm now trying solo, mage is pretty straightforward but I'm finding rogue impossible. I can get through Lothering easily enough but after that it becomes horrible, my rogue doesn't have enough health to survive even a basic encounter like three bloodmages in the Circle or elite werevolves in the Forest or a gang of wraiths in Redcliffe castle.
I'm guessing this has been done successfully several times before but I'm out of ideas.
