Then why aren't we learning tricks besides 1d in mundane defense?This seems premature. Right now, there are easily 12 things we could put dice into that would all give us more benefits than being partway to mastering something. Once our low level skills are rounded out and we have a few more tricks, we can start doing things like this, but right now I'd rather have a new and different trick than be at 70 successes away from Mastery rather than 80. It would potentially get us the Mastery a little earlier, but we're talking about a turn or two earlier in all likelihood, and in exchange we miss out on a trick for dozens of turns. Once there are no new tricks we want urgently this becomes much more appealing, but I can think of at least 3 or 4 we still want quite badly.
Like, the one die at a time thing maximizes successes per die, but it also caps total successes on the project each turn to the point that I don't think it actually winds up worth it for the really high success projects. Like, when we decide to Master our Inertia trick, that's easily 11 turns at 10 dice each of us just training that and nothing else. We could cut it by one, maybe two turns by investing a single die for 10 turns first, but we'd then have one less Trick for the 10 turns we are just working on Mastery...I don't think getting the Mastery maybe 2 turns faster is worth losing out on a different Trick for 9-10 turns (or being 10 successes behind in other ways).
Her Goddess was stated as foreign by our QM. That makes her likely, though by no means certain, to be foreign as well.
I mean, we could also ask him to train us in additional hugenreida or even seidr tricks and get that information that way. A meeting with the seeress might well also provoke an explanation on the seidr and is something we want to do anyway when Summer comes around.
I'm not saying I want to stop learning magic, but for the same cost as Mastering our current spell we could learn nine others. Nine might be overkill, but I'd rather pick up at least another one or two before we even decide which we want to master. Our current inertia trick is a great candidate (I actually think our healing isn't...it's rare to need it more than once or twice a fight, and by the time it was Mastered our orthstirr will be such that we'll be able to afford it when we need it), but I don't know that it's the best one, and won't until we have a few more options.
There a mass of dice could at least get us a better defense trick.
Or ask for rune lessons as @TheCount suggested.
