I finish off the DLC in New Game+, beating Artorias after about an hour of struggle and Manus legitimately after, like, three tries, all the while accompanied by me mumbling along to music I only half know the lyrics of while subconsciously muting myself because of my deep self-loathing.
Also, I get the extra dialogue from Dusk and Elizabeth, interact with Lord’s Blade Ciaran, and the cutscene where Hawkeye Gough shoots Kalameet out of the sky.
