Thanks for the tip off, had not seen one yet so thouhgt we'd go take a look.. then we just couldnt help ourselves and had to try and kill it!
Me and Ferrut spent about an hour jousting it down to half health, but then it started healing itself and we got no further
But it's gone now!
Some helpful guys (and/or gals?!) of Saor joined us to finish it off, then spawned another two! They were considerably easier!! Thanks for a fun evening
