I beat Morgott with my harp! (feat. harp bow)

It finally happened; I got the harp bow! It's possibly the worst bow in the entire game, but I had to do it for the memes.
Although I'm aware that I shouldn't continue to shoot poison arrows at an enemy after they're already poisoned, at the moment I can only do light attacks i.e. I can only use the first arrow slot. Also...I definitely did not show the correct screen at the end, so for those of you wondering, my bow was at +9 and I believe my talismans were Arrow's Sting, Arrow's Reach, Radagon's Soreseal, and ???. This was from a few weeks ago, so I don't remember the last one, but I think it was Viridian Amber +1.
