A boss from "The Old Hunters" DLC
This guy is really not that hard, maybe i'm just a weird player, but he didn't kill me once and the first boss did. Oh well, a cool fight. His moves are fairly obvious.
Update - Okay so I found this boss easy on NG+ but on NG++ his damage output was insane. He 2 shotted me a number of times, where as some bosses, such as Maria I didn't find harder at all, in fact I don't like how easy she is :|
The only thing you need to watch out for is the final phase where he leaves lava on the ground, do not get cornered and surrounded by lava and do not let bad camera angles beat you. Don't lock onto him, instead manually target him otherwise you may find it frustrating.
Cheers!
