And what is there is just a rehash of the main game. Only instead of the elden throne you are trying to reach the "god gate" and instead of Melina you burn Mesmer. Actually its more of a abridged version because in the main game you at least can choose between frenzy flame and Melina but the DLC(despite having Midra, a literal lord of frenzied flame in it) does not afford you even that.
In fact it kind of gets hilarious the further you go because it becomes obvious the Leda and her simp clan have no reason to be in the shadowlands and are just following Miquella to... map out his discarded limbs? Leda at the end in fact appears slightly enraged that you came to kill Miquella when in reality you have no idea if there even is a point to it. For all you know the divine gate is defunct and the only ascension Miquella is going to have is to an early grave seeing as he gored himself all over the shadowlands.
Leda: "You came to kill my dear Miquella!"
Player: "Ehm, I did? Well, thanks for letting me know. I guess..."
I have to seriously question if this is not another case of "The Old Hunters" where they had two DLCs planned out but then some exec decided it will only be one DLC so they just merged whatever was done into one package and that was the end of it. Story or coherence be damned, we got to move on.
