If ALASTAIR gives Sieglinde 'innate' magical power (and by extension, the ability to learn all the spells known by characters in-game), she'll have to trade away the effectiveness of her current ALASTAIR-granted spells by half, and she won't be able to gain any more. We'll also apply your suggestions of having spells she learns from others be at a lower effectiveness, and require training to master.
As this would be a one-time magical upgrade, above and beyond single spells, we would price it at 500 coins.
