So I fought Demon of Hatred down to his first DB today. I still have to finish grinding out the skill points to max out my attack power, but he seems pretty easy so far. Once I get the final two attack points I'll go back and finish him up. The fire umbrella puts an end to his jumping attack, and all his other attacks so far are telegraphed pretty hard. Fang and Blade Skill with the Umbrella wrecks his posture.
