How to forget a random talent?

[Zomborez]

I do not quite understand how the effects of forgetting knowledge will work, if all the heritage of knowledge is already open. I would like to forget 2 talents (Literacy: Celestial ; Literacy: Draconic) and replace them with something more useful (because all spells have already been learned). Scroll of amnesia - you forget random talent\ spell\ or other knowledge (about the rings, amulets, etc.)?
Blessed scroll of amnesia - ?
cursed scroll of amnesia - ?
cursed scroll of knowledge - ? (one time I accidentally forgot Literacy: Draconic and it was great)
charm Book of Fading Memories - ?

I will be grateful for your help, because to do experiments with forgetting knowledge can lead to death my new strong mage (with ebben ring)

That's something you probably have to learn yourself :(

I'm barely familiar with cursed scrolls effects (I know that cursed levitation drops boulder on your head, poly scroll polymorphs you instead and banishment instakills you, that's why I never use scrolls until I id them lol)
I'm not sure if such scrolls exist at all btw, you can't find blessed or cursed scroll of bless for example, maybe blessed amnesia does not exist as well.

Blessed amnesia and cursed knowledge are both 100% talents. Everything else can remove a talent with varying chances.

nibbe, thanks for this information!
Another small questions, is there any benefit from talent "Strong Will" - if player already have immunity from fear and curses?
Any benefit from "Dark Vision" (except light radius) and charm "eye of the beholder" - for mage (spell) attack?
Any benefit from blessed runes? (already known - 2 times use)

it's a bug. Just reload the game, you don't have to complete the challenge again
