Oh the brine king really isn't hard.  For this one it really is having the confidence to sit on him and take a couple of elemental hits and avoiding him when he does the big slam.  But bring along a flask just in case he does hit you.  Like Dominus, sometimes the safest place is on the boss when the waters rise.  It's just a bit of ducking around with him. But also, remember what you told me, kill them before they can hurt you.  He's definitely one of those bosses. 

Doedre was a lucky one.  It ended fast, but could have easily gone badly.  

Love my wings I do!!  So thanks for the compliment!  <3
