You need something fast and powerful to get to the blind spot under him. Terror Bajaj's are ideal since Khronos Shields give bonuses to Earth. Goal is to get under him to the blind spot. Wolves and goblins should not be too much of a problem. Avoid Shadow Lord's devastating special attacks. he heals 10x the hp of anything he kills with any normal attack.
This should do it. Good Luck!
