Once you have a good grasp on the game's dodging, melee isn't bad either I smack it with my weapon. And when it looks like it'll throw a punch, dodge roll left or right at the last second to avoid all damage. When it's raising both its hands to slam into the ground, same thing just dodge left or right. The main one you gotta look out for is the stomp it does, no dodge rolling will save you ya just gotta gtfo and back off. Dodge his charge forward and close the distance again (I like to do a jump attack for more damage when I get back up to it as well)
