What's the "Witch" profession supposed to be? If they are a sorceror, then what is their Grimoire access? In a Gloranthan context, where most grimoires are hugely rare and precious, how does an independent sorceror get access to one? I guess there must be Grimoires that are not derived from the Abiding Book, for instance Mostali grimories, and possibly Trollish ones (although they may be derived from Arkat's grimoires).
I've created a Witch as a sample character for my group, and I gave him three Grimoire skills and will allow the player to pick spells from any of the three but they will not have access to a grimoire to learn more without acquiring access in-game. The rationale is that he stole or cheated his way to get access to them.
If you have a Grimoire skill, and you come across another grimoire that has one of the same spells in it as yours, could you learn that spell from it and cast it with your existing Grimoire skill? I think so, as long as the Grimoire is culturally similar, e.g. both Malkioni or both Stygian.
