High level play and "reverse LA"

[Tequila Sunrise]

Just because weird stuff like this get under my skin: why CR 9721? If you're going for a thought experiment, why not round off to a nice even 10,000?

I'd also like to point out U_K's numbers are pretty accurate at lower levels too; I haven't even looked at DMG encounter level guidelines in almost a year; yet I haven't run any encounter who's difficulty wasn't spot-on where I intended it. An 8th level group of 3 characters, even in a low magic setting, can take down a marilith if they go all-out and fight intelligently. The DMG won't tell you that. It would say it's suicide. The party killed the marilith with no casualties. (Though it was a close fight, and most of the characters only had a few hitpoints remaining)

I was a bit skeptical when I read his rules for the first time, but after seeing them in action in my own game I was instantly convinced. Another vote for UK's work!
