So the last few plays I have been forced to do it offline as it just will not connect, I've beaten Aldridge of the deep, took many attempts and some swearing, then i beat Yhrom 2nd go, and also Oceiro the Consumed 2nd go.
after a little exploring i stumbled upon Arch drake dragon boss, and did such little damage it would have taken ages but i died to the snake heads.
My friend who say's co-op is cheating has no used it more than me lol, even tho i keep saying its part of the bloody game.
Cant wait to get this play through finished and then try a new build.
