A few comments from my GM have me a bit paranoid, so I thought that I'd brush up on my foci-being-targetted-by-spells lore a bit. Specifically: What can a mage do to prevent it, and how easily are foci actually destroyed?
It seems to me that any half-assed mage with powerbolt can just target your foci, let fly, and deprive you of handfuls of spent BP or tons of karma in an instant. Perhaps you'll get lucky and manage to resist the spell a few times, but provided that you keep encountering some mages in the campaign, it almost seems inevitable to eventually lose the foci. I mean, a force 5 powerbolt targetted to a shaman's foci (made out of bits of hide, teeth and what not) would instantly destroy it given a single net hit, right? That's not that hard to do, considering the foci resists with force (+ counterspelling I guess) so even a mage with 10-12 dice has at -least- a 50% chance to pull it off.
The prospect of having to beat those odds every time we encounter enemy mages or lose roughly 20BP isn't very comforting. Anyone can relativize this a little bit?
