Spell Unscribing Quest

[Rezum]

Hi, I've been trying to find a way to #unscribespell() (recent addition to commands), but doing it using a quest script... Reason being is I currently use quest::scribespells function on an NPC Spell Scriber, but doing this also gives the PC's their discs in spell form, so they can use the disc, plus scribe a spell and use both one after the other (only viable for hybrid classes that have both discs and a spell bar). So I was looking to see if I can scribespells with a quest, but then straight away unscribe the disc's from their spellbooks.

Either that or is there a simpler way to do this? to stop Hybrids using discs and spells (I dont want to not give access to the spell scriber as its a very likeable commodity for a custom server).
