Again, a drawing is not the reality
A sword does not break in dozens of piece
whatever the strength of a weapon you forge it to be solid and no matter how you forge you will not make a sword that breaks in pieces
there are alloys that react in this way (and heat treatment), but never will a blacksmith use them to make a sword
do not believe the drawings, find out how it was done, because it was made to be usable in optimal conditions for the fighter
swords were often crooked/twisted during battles and hammer/ax handles was sometimes broken
and if the metal part broke it was not more than 2 pieces
the price of labor was almost nil at the time, the lord had blacksmiths and could requisition others present on his territory, it was close to slavery
the price of the labor was to feed him his family and the maintenance of his house, to say almost nothing
yes she alone is useless, but an army without her can never kill monsters too strong, so this army is expensive and useless ...
The kingdom needs someone very strong, she was already there, but the kingdom did not know how to use her
just teach her how to fight and it would have cost the equivalent of repair for 20 to 50 people per fight
While she has the strength to beat monsters unbeatable even by big number
and I do not even talk about people who will not die thanks to her
"It's also worth noting that she changes her sword more than just when she connects with the claws, and even previously she broke her sword before the bears. So it's not just the claws."
before for the mithril sword, it was after typing something very hard
and I already explained that it's not like that we use a sword
the claws of a very powerful bear as described are necessarily as hard as weapons, knowing that even his skin is almost impenetrable
so look for weak points and attack them not the claws.
"the MC isn't Wise, because he hasn't fixed that problem"
it is true that it lacks a technical and logical explanation, but it should have been learned easily if the kingdom had done is work of training
because she missed almost nothing, she had the speed, so the time to place the shots in the right place
but nobody explained to her how to use a weapon and what not to do with
"And the only reason it ended up fixed is because the MC did what was literally impossible for teh government to do and give her enough swords that she's confident that it wont matter if she breaks them." for all that I said previously I do not agree
I think the problem is the author, he does not know anything like most authors and made choices about the power he gave to the hero, so not necessarily logical/real choices
He could have made this story even more interesting and realistic if he was looking to fix the girl problem
maybe a power with more limit would have been more interesting too
can only multiply an object once and the new (harvested) can not be multiplied
this rule does not apply to plants because the planted product (seed or rotten fruit) is only a part of the harvested product and its "alive"
it will have forced him to find a viable solution for the girl and made the trade part more interesting
