Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

My wizard who is focused in Conjuration with the opposition school of Necromancy can still cast any and all Necromancy scrolls.

I know others have this 'issue' as well but with different school combinations.

It should not allow any spells, even from scrolls or wands, to be cast from the opposition school (this is what the opposition school feat says in-game). Is this an error with the new 'select your opposition school' feat, or has it been changed on purpose?

I wouldn't really want to use Necromancy scrolls if it's deemed as an exploit.

This is considered fair play. The system isn't designed to restrict you from using scrolls, only from memorizing or casting the spells yourself.

Thank you for the swift answer. Glad to know it's OK.
