Forbidden school: necromancy, yet able to use necro scrolls

[Hoihe]

Hello!

I'm playing a wizard who is a Divination specialist. Her forbidden school is Necromancy.

While buying scrolls, I noticed necro spell scrolls were no longer red. I bought one, Death Armour, and it worked as if I didn't have necromancy forbidden.

It might be worth noting I have 20 modifier Use Magic Device with 16 ranks.

Is this intended for UMD to enable characters to use scrolls from a forbidden school?

There is no UMD roll shown, unlike for divine spells like "Cure Serious Wounds."

You can use all wizard scrolls, regardless of school prohibtion and UMD score, when you're a wizard. I don't know if that's ok lore wise though.

Trick is, I didn't use to be able to use necromancy scrolls at all! They were red

I don't know when it happened that I could.

Per the wiki:

Spells of the prohibited school or schools are not available to the Wizard, and he can not cast such spells from scrolls. He can use wands with prohibited school spells though. He may not change his specialization later.

This does not only affect a Wizards spell selection; school specialization takes precedence over other base classes or Use Magic Device checks.

For instance, a multi-classed Wizard/Cleric can not cast Clerical spells from the prohibited school. So if that Wizard/Cleric has Conjuration as a prohibited school, he can no longer use Resurrection scrolls. It also means that the tip from the official rulebooks of taking a level in the Sorcerer class on a Specialist Wizard, to yet gain access to all arcane items from the prohibited school, does not work. (However, see Talk:Wizard)

However, it seems lore wise it's fine (the Official advice of multiclassing to access forbidden school items).

I guess this isn't a bug but a feature then?
