It really doesn't matter. At all. Even if you think you can disregard that specific quote as an invocation of rule zero and therefore a change of the setting by DM fiat, the original assumption that the CR 3 vrock is out of line with the D&D setting posited by the MM because the weakest vrock is CR 9 is totally bullshit someone made up. This is what the MM actually says about the CR 9 vrock (or rather, stat blocks in general):...You Lost Me wrote:Fuchs, saying "it's in the rules" isn't even an argument. The fact that the MM has a quote saying "the DM can do whatever he wants to the monster" is not justification that the rules support scaling monsters down.
Also, Avorio has a vrock. Could we discuss that?
And we're done. That's it. It turns out the CR 9 vrock is not an explicit min that the GM is changing by rule zero. It turns out the CR 9 is an explicit mode and the existence of CR 8 vrocks is already compatible with the MM. It doesn't tell you how to make those CR 8 vrocks, but their existence is compatible with the rules text. Baby minotaurs actually do exist in the setting even if D&D doesn't tell you how to stat them up.SRD wrote:The monster entry usually describes only the most commonly encountered version of a creature. The advancement line shows how tough a creature can get, in terms of extra Hit Dice. (This is not an absolute limit, but exceptions are extremely rare.) Often, intelligent creatures advance by gaining a level in a character class instead of just gaining a new Hit Die.
Kaelik and Co are arguing from the standpoint that only actions and entities governed by the rules can possibly exist, therefore since the game doesn't tell you how to make a CR 8 vrock, even if a CR 8 vrock is compatible with the text implicitly or explicitly, it can't actually exist because the rules can't produce it. That falls apart as soon as you point out that the rules are necessarily incomplete. For example: D&D does not cover reproduction. No one's character has ever been born, and if you mention having parents in your background you aren't playing D&D anymore, you have rule zero'd it into the game and are playing something else.
They are ultimately right that "you should tell your players when you introduce weaker versions of things," they are simply wrong about why. They think a CR 3 vrock is incompatible with D&D as written, which means they also throw a fit when you introduce a baby minotaur without telling them babies are something that exist in D&D. That's very dumb. The much more reasonable position is that nobody actually plays D&D by exploring the depths of the lower bound, so when you introduce even a single CR 3 vrock (again, wholly rules text compatible), you are fucking with player expectations in a way that is genuinely disruptive to the game.
