Disclaimer: this is purposefully obtuse.
Other effects in the game which explicitly state they kill you:
Shadows, succubi, massive damage, death saving throws, beholder death ray (notably not even their disintegration ray kills you), power word kill, vampires, mind flayers, night hags, drow inquisitors.
Clearly, if they intended for disintegration to kill you, they'd have said so. Since specific overrides general, and there is no general rule that disintegrated creatures are dead, I rest my case. QED.
Where does it say that, RAW? I'm using your own logic against you. You'll have to come up with a better response than that.
Edit: to clarify, where does it say RAW that you get to continue playing when polymorphed into a non-playable character?
Imagine a GM that takes control away from a druid player any time they wildshape, smh.
I mean, this is a game where we are being intentionally obtuse. I don't care about the game in any capacity. I care about what is written in the rulebook.
Feels like you may have lost the plot of your own joke post.
There was a plot?
So you're just giving up and not engaging with my point? That's super boring.
You can only beat a dead horse so much. Sorry mate. Hope the rest of the thread was entertaining at least.
