Presumably a 10+success design from an Exalt has fixed all those defects.
And even if it didn't, the principle of it remains.
I don't agree.
As has been said, there are lots of options for this already. If all else fails and you're willing to do this then you could also just kill them all too.
It looks bad in movies, but morality tales from Hollywood aren't always thought out well.
This isn't inherently any better or worse than any other weapon, because people invariably get hurt when you choose to attack them.
The whole point of this idea is to try to control how much they get hurt so that you can ensure more people survive. It looks nasty because the whole topic is nasty cover to cover.
If your goal is simply to inflict suffering there are better, cheaper, and easier to access mechanisms that have been used for years.
Ones that are just as obvious evidence wise, since this leaves witnesses unless you kill them all anyway.
We should present Daniel the options, and let him choose maybe? I still think it would be better for him not to try and be a pale imitation of MIchael / Molly's swordfighting aspect, but his own thing.
[X] As Kris Kringle, The Gift-Giver, The Toy-Maker, The Old Elf of The North Pole and Master of The Workshop.
He's not going to stack up either way, but I legitimately think he'll do better with one than the other*.
I'm less worried about Olivia now since it's been clarified she isn't a couch potato, but she still isn't a melee fighter and her best skills don't benefit from it.
* worth noting that he'd actually be pretty good at this. Assuming 3 dex/strength and 3 melee, representing someone good enough to be in a fight but not particularly outstanding, he's rolling 6 dice.
With Certiorari that's mostly against difficulty 4, he doesn't botch and gets either a single guaranteed success on anything he does unopposed with a sword or +2 successes when opposed. 2/3rds of the time he's going to roll 4+ successes, boosted to 6. That's pretty damn good, competitive with Molly when she's not burning excellency for it. As is he can solidly counter mooks and play tag with the next league. 1-2 more dice and he's in the "stay out of reach" range for a lot of things.
It also doesn't account for the powers that the will of Kakuri already put in the blade that we haven't gotten a report on yet. The processes we're applying to it don't actually remove the base item's power, so Daniel should get to use whatever nonsense is already present too.
That clause about never failing unopposed rolls shouldn't be underestimated either. As a core ability of the blade it's the sort of thing he should absolutely abuse the shit out of.
If he can figure out how to theoretically make his sword maybe do something he gets the basics technically successful result. Cut out of a sealed steel box? Sure. Cut a brick wall in just the right way to collapse it on someone, or behind him as terrain hazards for followers? Probably. Get at least 2 points of active defense against things he shouldn't be able to, like bullets? He gets successes in anything possible regardless of how improbable it is, so why not?
The more creative he gets with making things technically count in the one area he can't fail that aren't combat the more bullshit he can be.
Fortunately for him he's got a ride along spirit with the ability to see the future in multiple different ways and superhuman intelligence to help him min-max. Lose track of him for a moment and he could very well show up in the one place that a sword which a sword that can't fail even the most ridiculous effort without the effort of a thinking opponent can screw up their plan.
But this is not canon Daniel. He is in fact very different. Due to being Lydia's boyfriend he became much more occult oriented, trying to learn magic, and it also likely has to do with Molly. In canon Molly was a pure mage, so being a sword fighter could be his own thing. Here, Molly is a transcendentally good swordswoman and regularly fights evil with her flaming sword. Hence Daniel seeking something else. He might still go for the sword, but I think we should ask
Things haven't changed until fairly recently in his life. He's already built to wield a sword at this point. As a mortal he has very little room to backtrack and get anywhere on a relevant time table.
And, again, the mortal user is literally a part of the splendor. The splendor is built as their hero's shadow. Chances are, if taken away and kept away, the splendor would simply stop working.
Just to be clear, since you were arguing another this earlier, splendors survive the death of their owners and are automatically transferred to anyone who kills them:
When a Splendor comes into being, its creator automatically gains ownership of it. From that point, there are only two means by which ownership can be transferred. The Splendor may either be intentionally given to someone else, an act requiring conscious and deliberate choice and the expenditure of one point of Willpower; or else the Splendor may be taken. This requires the murder of its current owner. Ownership of the Splendor automatically transfers to whoever was most directly responsible for its former owner's death.
If the owner of a Splendor dies by natural causes, by their own hand, or by accident or mishap that is the fault of no one but themselves, then they pass into the underworld as a wraith and continue to own any Splendors they possess there.
This isn't a reason not to use them though. We can take steps to make them useless for anyone who does this, and there aren't many other credible options for making mortals not suck on a short time table that have reasonable consequences.
Also, I'm not concerned so much about actual theft as I am the idea of it. If we give someone a ring that provides them with significant power, whether it can be successfully stolen or not doesn't matter to anyone who sees it and covets that power.
Much better for the power to appear to originate with the person rather than an item they are wielding, for a number of reasons.
To be fair, this is the DF and not DND.
Artifacts can be and are stolen, but the ones with real power tend to have tricks that make taking them dicey if you don't know exactly what you're getting into.
Stuff like the spirit inside getting pissed and doing things to you when you try to use it, which we can actually arrange for.
Edit:
Hmm, if we are able to afford buying exalted craft this turn (in addition to the kingdom), we should think about making Christmas presents with it, as AP spend action. I have some idea for minor (2 to 3 dots) splendors for people. I'll have to think about it.
We have to kill people for those, 3 dots in particular is where they get spicy. 1-2 at most, because we can technically do stuff like target the weakest people who technically count as elder vamps for example.
