Wizard Spellbook: Where is all the space?

[Crake]

As an aside, can we all agree that Sanctum Spell is one of the worst-written pieces of rules text in the entire game?



The level of a spell is a quality possessed by the spell, not an effect caused by the spell - let alone one whose effects can be calculated.

Badly written implies that the feat is vague and hard to interpret. Sanctum spell is actually very concise and clear in what it does, so I'd say its quite well written. Now, as to whether or not it's game breaking and poorly thought out/implemented for what it was intended to do, that's a different question.
