Same. I learned of it when it appeared in my Youtube recommendations.
Even if they aren't, there is definitely too much mayhem in Mordenkainen's Mayhem. The matron mother manages to banish the nightwalker, only temporarily as the fight is taking place on the Shadowfell, and an angel randomly takes its place while it is away. Just why? It is not to keep the fight going, as the allip is still here. It is not to showcase a new type of angel, as it is a planetar.
I am also disappointed that they went with "Underdark versus Undead". That's not thematic. It is barely a pun.
Will you be making more threads to analyse the fights, or does it feel pointless now?
I don't really know nightshades, so all I can say is that the art for the nightwalker is really good.
And the allip is like an even more tortured ghost than the specter? Is that it?
I am not a native English speaker, but the first thing I thought of when I read "matron" was the French word "maton", which is slang for jailer. Wiktionary tells me that it matches one of the meanings of matron.
So, it doesn't evoke such a kind figure to me.
The art is pretty pink, though.
