@Flotus with extreme difficulty. I use Heavenquaker Spear and Stratergic Sword. Also, I have the swap stance technique. It was very difficult, but I managed to barely kill it. The reward is great though. You get so many talent points. I actually unlocked 2 talent sloths with it.
Don't put me together with those shallow swamp dwellers who enjoy fan service and cheesy harem. I am someone who looks beyond simple harem and comedy and enjoys a good story.
