Dysfunctional Rules X: I Cast Comprehend Rules

[glass]

If you don't noticed, it's the "Dysfunctional Rules" thread - it's chock-full of false rules (blatantly or otherwise)

It's full of dysfuctional rules. It's full of of rules that are badly written or just bad. Occasionally, it's full of rules that are fine but have been misinterpreted.

But it can't be full of rules that are false. A rule cannot be wrong about what it is saying - if it says something, by definition it says that thing!

I mean - if you can explain how (or when) to make Leadership checks by RAW...

To the best of my knowledge, there no need or method to make leadership checks - that is what makes the subject of that post dysfunctional. But it doesn't make it "false" - if such checks were introduced, the item would add +5 to them just like it says.

No, it doesn't says so.

This is confusing, because a few posts ago you quoted its saying so, thus:

The problem there is: the "... can be slain only by ..." line is blatantly false

(Plus your SRD quote in a previous post).

Either is says it, in which case it is not false because it makes it true by saying it, because that's how rule work! Or it doesn't say it, in which case it isn't false because it isn't there at all. Unlike Schrodinger's cat, it cannot be both. Yes, I know Shrodinger didn't believe the cat was both alive and dead - he was trying to ridicule Quantum Mechanics not explain it.
(For the record, its the former.)

Rules can have exceptions, implicit or explicit. But if having exceptions made a rule false, the vast majority of the rules in the game would be false.

There are numerous ways to kill the tarrasque without resorting to Wish/Miracle

Quite possibly, but each of them is an explicit or implicit exception to the stated rule. And suffocation is not one of them - nothing makes suffocation an explicit or implicit exception to the tarrasque's clearly stated rule, so it cannot kill it.

Spoiler: Implicit examples

Show

For example, form-changing spells:
Arboreal Transformation (Complete Mage) and Touch of Juiblex (Book of Vile Darkness) are both turn their victims into plants ("a normal tree" and Green Slime respectively). After the transformation is finished - what's prevent us from burning it down (and, thus, killing the tarrasque without using Wish spell?)
Heck, even "simple" Baleful Polymorph may do it there (possible successful saves aside): once 24 hours is over - it's a little critter without any unusual abilities. After that, you can just stomp on it. (Or, you know, set it in a cage for it to die of old age in a few years - anyway, it would be dead)

Or, you know, Mind Switch - if Grim Psion successfully manifest it on the tarrasque, they would be in the tarrasque's body while keeping their respective class features, and the very 1st level of the class gives Undeath: no Con - no Regeneration, and no Regeneration - dead tarrasque

These OTOH (assuming they all work) are fine examples of implicit exceptions. The tarrasque's invulnerability is provided by its Regeneration - remove the one, and you remove the other. A rule not applying is not the same as a rule being false.
