MapleStory Dark Knight Extreme Seren solo CLEAR (HEXA 118,510)

THE MOST CLUTCH XSEREN SOLO CLEAR YOU WILL EVER SEE I had to use Frieren skills during bursts and Hecate binds ("miniburst"...) I WILL NOT TOUCH THIS &$!@ BOSS EVER AGAIN not until I can get myself the damage for comfy 20min clears (or maybe until 20 min timer change arrives). Just like in Destiny Seren, I feel like min cutting this boss feels like learning it from scratch all over again.
