From the description of the blade, I was fully expecting this to be an evil thing. Yet it is one of the noblest weapons I have ever read about. I'm glad that you took the extra time to write this up, as the lore section was a very enjoyable read. This item could also inspire the right player to do some great roleplaying, and that's always a plus. 4 for the original idea + 0.5 for the excellent lore.
I really, really like this. It's obvious that you put a lot of time into this sub. His physical description made me smile, and I was expecting him to be a kindly spirit -- a twist on Pinnochio, perhaps. His actual personality caught me off guard. Still, I can imagine that a party would be quite willing to help the little guy out once they learnt his history, and that could provide a whole mini-campaign arc to build around. Well done!
Some of these are a bit too "magicky" for me, considering that this is a 30 based on unintended consequences of R&D. "It's Alive" and "Infernal Contraption" are two cases in point. Still, this is a genuinely useful 30s sub with many good-to-great idea seeds.
Breaking down social barriers with a MASSIVE hammer is a pretty funny idea. I'm not sure exactly how it would work, though. Does the bearer just walk up to someone with the hammer strapped onto his back and engage in conversation, or does he have to hold it threateningly? I can imaging that the effect is not entirely magical in nature, as the sheer size of this weapon would be enough to intimidate most sane people. . .
I can't imagine that many good women would wear this thing willingly, if the evil presence becomes apparent to anyone who puts it on. It could be given as a gift, though, by someone who wishes them harm. Anyone who dons this knowingly probably has evil intentions already, and deserves their eventual fate. What good does seducing the crown prince do, if he will be killed by his own guards shortly after?
Another one to file in my brain's "weird shit" compartment. A creative player could probably find many more unconventional uses for such an object. I imagine it to look something like a cross between a Dali and a Picasso painting, though I really wish I could imagine how it sounds!
Huh. This is perhaps the strangest weapon I've come across yet, so you get points for that. For lack of a better mental category, I'm going to file it under "weird shit" for now. :P Interesting backstory, though it could be clarified a little with a rewrite. I also notice that you didn't use the required format for this sub, as given in the quest description. It may be interesting to know what the enchantments on the original three daggers are, as well, just so that we can get a true grasp of this thing's potential.
Overall . . . Dossta likes. Good job!
