The number that replaced the numbers
D&D is the only franchise here that has printed god stats and then stopped.
The older editions did it comprehensively. Deities & Demigods statted whole
pantheons; Faiths & Pantheons did the Realms. The consequence was inevitable and
famous: given a stat block, a sufficiently equipped and sufficiently determined
party works out how to kill it, and a god you can kill with enough preparation is
a monster with a large hit point total. Fifth edition’s answer was to stop
statting gods as things that can die. The handful it does stat — Tiamat, Vecna,
Auril — come with the escape hatch written in: beat Tiamat and she discorporates
back to the Hells, unable to take form for a while. The stat block is a weather
event, not a life bar, and that says more about divine power than any number the
older editions printed.
What remains is Challenge Rating, and the rules are honest about what it is:
that an appropriately equipped, well-rested party of four should
beat a monster of their own level without a death. It is a scheduling tool. It answers “will this kill four adventurers of level N”, which
is a question about the table and not about the setting.
The gap is visible from the top of the chart. The joint-highest CR in the game
is shared by Tiamat — a goddess with a portfolio, worshippers and a plane — and
the Tarrasque, which is an animal that eats a village and then sleeps. On the
printed number they are equals. On anything else, they are not comparable, and
the page reflects the second reading.
Ranked at peak, across incompatible editions
This page has a problem the others do not: its subject has been rewritten from
the ground up six times, and the entities are not the same entities between
versions. Vecna is a lich in one edition and a god in another. Tasha and Iggwilv
were separate people until they were retroactively one.
The site’s rule handles this the way it handles Hulk states — a character is
ranked at its peak, and the other versions are listed as forms. Where an edition
change is genuinely a different being rather than a different write-up, the entry
says so rather than averaging them, because an average of two incompatible
sources is a number with no source at all.
