@OfficerRattlesnake In a world with magic, we can’t make fire run through the blood veins of a person. If we can control fire, I don’t see the need to make it scientifically possible, as magic itself is not, scientifically plausible. To me, that also applies to many of the things being discussed, in a video game with magic, why do things need to make sense. In some books, magic is the ability to do anything, you just need to give up something in return.
Yes, how much is 1k gold, how much is the sword worth? I’m sure that there are rich people in this world that can afford it too, the king is not always the richest person in his kingdom. So, a sword with a burning effect won’t cause more pain than I normal sword? Elements, fire, water, earth, air, lightning, these are the standard that I have seen in books, and games. What do they do? I would assume that a sword with water, could do ice, which would freeze flood, or maybe a single limb. As to how, once again, its a world with magic, and enchantment could do this, technically a really good blacksmith could do a high level enchantment.
I want to respond on the dark/light thing, feel free to skip this, and I’m sorry for bringing it up but I just want to get my point across. Light and darkness, yes, they are a poor morality scale, because there are different shades of grey, maybe 50. Its a thing commonly done though, even fable has a similar scale, by making decisions your character can look evil with horns, or have blue/white wings. Even though a poor morality scale, it doesn’t always mean that. Take a demon for instance, in one game, I can’t remember the name, it’s a monster that is considered dark, but it actually is a good character, that is well liked by those that truly know it. On the other side, in a book I read, an angel, that was considered to be light, acted good, but actually tried to kill innocent people and gain power. So, individual creatures can be considered of light or darkness, but that doesn’t mean they have to act that way.
You contradicted your self,
If it does more than a normal sword, has properties that no other sword has, that makes it more dangerous in battle, then it is more useful.
