Wizard Spellbook: Where is all the space?

[Ruethgar]

No, you're still trying to apply metamagic to the spell being learned/scribed...(stuff based on false pretense)

This is in no way a case of "specific trumps general". You literally are trying to apply RAW incorrectly. It doesn't matter that Sanctum changes the spell's level; it still only applies at the moment of memorization/casting, not when trying to learn/scribe it. None of the text in that feat changes this. It only says that when you apply Sanctum to a spell, you alter it's level for the purposes of casting it (+1 spell level in sanctum, -1 outside sanctum). But it only applies when you cast it. It says nothing about altering the way the spell is affected in any other way.

Even the feat says it still occupies a spell slot of the same spell level. You can't even put a 1st-level Sanctum spell in a 0-level slot. It just counts as a 0-level spell if you cast it outside the sanctum, for purposes of save DC or other spell level issues. There is no such thing as a 0-level Sanctum spell; they're all still 1st-level spells.

So no. There are not "100" 0-level spells. Any player trying to sell you on that is cheating. Against RAW. I don't know how they actually warped you into believing this was legal by RAW, but it truly is not.

You seem to be confusing my assertions. I have never said you could possibly write a metamagic spell into a spellbook. Simply that wizards start with a spellbook containing all cantrips with no qualifiers on weather they are scribe-able or not.

You also seem to be confused on the wording of Sanctum spell. The lower level applies at all times after application of the feat except within a sanctum, this means a Sancum Magic Missile memorized by a Wizard is a 0 level spell. This comes into play for other things, such as sacrificing prepared spells for some other effect based on spell level(there was one horrid option for something like +1 att per spell level or something).

It is a case of specific trumps general in that Sanctum spell alters spell level like Hieghten does rather than only spell slot like every other metamagic feat in the game and as described in the general metamagic rules.

Occupying a higher spell slot does not automatically mean it is a higher level spell. An Extended Prestidigitation for example is a 0 level spell even though you can't put it in a 0 level slot without metamagic manipulation trickery.

Even discounting Sanctum, we were up to 72 cantrips before the application of spell templates which are treated as different spells from their base spells. You may not be able to learn or cast them without a feat or other special feature, but they are extra cantrips that would easily exceed the 100 spell mark.

This is easier to understand when you parse how the feat applies to the spell.

Q: Is a sanctum endure elements spell a 0-level, 1st-level, or 2nd-level spell?
A: It is a 1st-level spell. The base spell, endure elements, is 1st level, and sanctum does not change which spell slot it goes into (i.e a 1st-level slot). RAW says so right there in Complete Arcane.

This is false. If prepared, it is a 0 level spell for all effects that rely on spell level, such as defining whether or not it is a cantrip. When cast, it is either a 0 or a 2nd level spell depending on whether you are in your Sanctum or not.

Q: When you cast sanctum endure elements, is it a 0-level, 1st-level, or 2nd-level spell?
A: It is a 1st-level spell. For purposes of spell level, such as saving throw DC and other statistics, it is either counted as a 0-level or 2nd-level spell, but only at the time you cast it and not an instant beforehand. The spell does a quick check of the conditions where it is cast:
1. Spell is cast outside of the sanctum = -1 spell level applied when spell is cast. This in no way allows you to use a lower-level spell slot to cast it, even spontaneously. A sorcerer casting this spell still takes a full-round action to do it, and burns off a 1st-level spell slot. However, if he were required to make a saving throw against the spell for some reason, he makes the save against a 0-level spell, not a 1st-level spell.
2. Spell is cast inside sanctum = +1 spell level applied when spell is cast. As above, if you were forced to save against such a spell, you save against a 2nd-level spell.

Mostly true, except that it's not "if cast outside the sanctum", it is instead "if not cast within the sanctum" which is a much broader spectrum of states.
