I was hesitant to make the suggestion as I figured there was a good chance this was the case. Well onto my next idea: steal Hermione's deus ex machina Time Turner and start violating the laws of space-time.
You joke, but am curious if Jacob's father's space-turner can be modified to a time-turner. Of course, he'd probably need to get a copy of a muggle physics book.
@MysteryCPU, assuming that the no brakes plan wins, as much as I dislike it, do you have any ideas about what to do for the other class skills, since they could not all reach P- before the automatic increase?
Well, to be fair: none of the plans get all our class skills to P-. The exploration plan does put potions at P-, which will be a P. Which helps in potions development.
I don't really have any plans in mind since most of my plans that had efficiency in mind were not voted in. If no brakes wins, we will have to see how the rolls go: if the rolls go well we have some cushion. Heck if the rolls go well consistently, we will have more options. If not...we will probably have to eat a Ravenclaw bonus or two (or more on really bad rolls). The idea of my plans and analysis is to minimze the need for luck.
We will have to level up 11 other skills, of which only 8 others are class skills. If plan no brakes wins, we probably would like to triage the class choices to focus on the 5 with bonuses to learning first and then try and up the class skills before too many Ravenclaw bonuses get added. Really, I was focused on getting class skills to P- not only because it would guarantee we were at above O level in all our classes, but because over the years at school, we could have 15 in all our class skills mid- 7th year and a lot of the pressure would have shifted. It also gives Jacob a pretty good all-around knowledge base.
Next turn, however, I am going to propose doing both the Riddle or Old World story, explore, and do 3 Rune Research. Then with the 6 personal, do 2 Alchemy train, 1 Potion, and 3 training on Patronus in order to work on the trait and to let us do the Hogwarts Map the turn after next. Then before the next Ravenclaw bonus, we should look into getting all the class skills to P-.
We should not do Potions training until we at least get the potion to P- (would be P if we do Explore plan). Each +1 increases the probability of success and adds on to higher DC potions rolls.
