Go back to Big Bend (entrance at ( 58, -12, 270 ) Copy/waypoint 58, -12, 270) and fight Skalmos. He will be on the pier.
Note: If you pull him off of the pier and kill him he will re-spawn another attackable version of him but you can still hail the NPC he turns into after death
Note: for level 100 Chars: when you attack him and his health doesn't drop really .. unequip all your weapons/armor/jewelry everything and just melee him bare hand
Once defeated speak to him and receive message to give to Gisuka back at Temple of War.
