Arcane School abilities and Multiclassing

[AzureKnight]

I mostly come on the forums when I have a rule question, but lately I've been reading more for the sake of reading and I've come across something that surprised me.

Wizard Arcane School abilities (let's use the Admixture ability)

Versatile Evocation (Su): When you cast an evocation spell that does acid, cold, electricity, or fire damage, you may change the damage dealt to one of the other four energy types. This changes the descriptor of the spell to match the new energy type. Any non-damaging effects remain unchanged unless the new energy type invalidates them (an ice storm that deals fire damage might still provide a penalty on Perception checks due to smoke, but it would not create difficult terrain). Such effects are subject to GM discretion. You can use this ability a number of times per day equal to 3 + your Intelligence modifier.

I've seen people posting that they will take a class (let's say Magus as I plan to play one) and dip one level into Wizard and then apply Versatile Evocation to their Magus spells.

After reading it, I guess it isn't exactly clear that is has to be a Wizard Evocation spell, or even an Arcane Evocation spell. This same thing can be found in many school abilities as well as some Cleric domain abilities.

To me RAI this never crossed my mind, but then I started thinking about it, Wizard gets Scribe Scroll too and that would work for the Magus spells.....what are everyone's thoughts on this? RAI? RAW? Do you play this way or allow this? I'm really curious.

Thanks,

Sorcerer: Do the bonuses granted from Bloodline Arcana apply to all of the spells cast by the sorcerer, or just those cast from the sorcerer's spell list? (page 72 of the Core Rulebook)

The Bloodline Arcana powers apply to all of the spells cast by characters of that bloodline, not just those cast using the sorcerer's spell slots.

General rule: If a class ability modifies your spellcasting, it applies to your spells from all classes, not just spells from the class that grants the ability. (The exception is if the class ability specifically says it only applies to spells from that class.)

Such powers generally work on all your spells, unless otherwise noted.

Hence the popularity of dips in admixture wizard, crossblooded sorceror, heavens oracle, etc etc...

Thanks, so many FAQs, errata and clarifications make it tough to keep track of all of them!
