How to kill Jounin with ninja-academy dropouts:
Step 1: Start a Cult
As with many effective plans, the first step is to start a cult. Be a personable person: indoctrinate others. Specifically, your doctrines are about the dangers of too powerful ninja, and the need to eliminate them. Make sure everybody in your cult knows from birth that their entire purpose in life is to slay Jounin/S-rankers and other high powered ninja. Make sure they all have all their aspects (7 I think?) related to defeating S-rankers, or serving the glorious leader, or being phenomenal at Genjutsu, or other aspects which can be tagged to hit Jounin with Genjutsu.
The
cannon-fodder initiates need to aquire 491 XP total. This should be doable with drop-out ninja in about a year. Their skills will look like:
Genjutsu 29 (435 XP)
Athletics 10 (55 XP)
Taijutsu 1 (1 XP)
Ideally, they can get more XP, especially if they can start getting XP in the cult relatively early. If they can, build up to a "beefy"
Genjutsu 39 (780 XP)
Athletics 20 (210 XP)
Taijutsu 10 (55 XP)
Awareness 1 (1 XP)
for 1046 XP. This is a few years of lowest of the low ninja experience, or less than one year for a talanted ninja like Hazou. These powerlevels should be fairly easily achievable by ninja academy dropouts power levels in a cult.
Ideally, have as many of these initiates as possible, for the sake of argument, we'll say you can find ~10 "beefy" initiates, and ~25 non-beefy initiates. This seems like a manageable cult.
Step 2: Recruit an ok ninja with a chip on their shoulder.
Doesn't need to be great, chunnin level is fine. Should be able to handily and defeat jounin, and possibly S-rankers (depending on how many beefy initiates you've got). Ideally, they're also either easily manipulated, or hate the opponent your trying to take down, so their aspects can trigger. Ideally build them up from within the cult so you don't need to recruit, and can min-max their expenditure and focuse their aspects. Their stats should look something like:
Athletics 40 (820 XP)
Taijutsu 40 (820 XP)
Anything else leading up to that point (731 XP)
= 2371 XP.
So, this ninja need to be around as experienced as people like Sakura are, but more focused on straight punching than she is (or more experienced and less optimized). Probably, hire a missing-nin for this role using the lure of "gets to be pampers and served by a cult" as a reward. They could be more optimized or have more XP, but we're limiting our materials here, and with the power of the cult, this should be sufficient.
Step 3: Find yourself an A/S-ranker to murder, and murder them
So, everybody needs to attack. Here, have all the initiates cast Genjutsu at once, triggering all their aspects in one go. The weaker initiates will roll:
29 (base) + 3 * 7 (cultish aspects OP) + 4DF = 50 (bounded between 38 and 62)
The stronger initiates will roll:
39 (base) + 4 * 7 (cultish aspects OP) + 4DF = 67 (bounded between 55 and 79)
Meanwhile, our erstwhile Jounin will roll something like:
Awareness: 60 + 4DF = 60 (bounded between 48 and 72)
So, let's say we have 10 beefy initiates, and 25 non-beefy initiates. We can reasonably expect to get about 10 tags off of this.
Now, have our chunnin friend attack. They'll roll:
Athletics/Taijutsu (probably Athletics, since they'll be on the defense): 40 + 5*10 (Cultish Genjutsu) + 4DF = 90
against our enemy's attack (probably around 60-70). This should result in approximately 20-30 points more than the jounin has, letting us do 7-10 stress, which I *think* is enough to basically take them out of the fight.
