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.
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.
