Or at least I had... It just has deserted my mind

That would be a good thing. Insidiae would have clearly benefited from such a weapon.
Of course, this'll be useless against anything with Magical Resistance, but... One problem at a time, they say 
Truth be told, I tend to favor permanent enchantments, that will persist once we're all gone, but, in the face of supernatural opposition, this requires way too much Penetration. So we may need to stockpile some Charged Items, not unlike Carmen's Lightning Rod, although this'll have to wait until you're a more senior magus. In the meantime, anything you can do for our grogs is a boon.

Well said. You are right, of course, we shouldn't neglect mundane expertise, although that is not my province. The goal in all our preparations is to achieve sinergy, for all our strengths to complement each others. Now, if that young Bernat has some ideas on how magic could help him, I'm all for hearing him. Otherwise, he'd be better served by going at... Arf... Vibria has left, and we are devoid of a Marshal. That ain't good*.

Arachné will be very pleased by your proposal, and, should you propose to create it, will heartily support it before the council.
And yes, IIRC, the training is permanently destroyed, but may be regained with some time and practice. This is not really doable in combat IMO (You can't really have someone show you how you gotta protect your pal's side while being confident that you other pal has you back and move only in relationship to them), but otherwise is no great hindrace.
