Ah and it says that Kun created it where? And the amulet is shown to do what exactly? Thanks for proving your infallible arguments as usual IKC!
Logical fallacies:
Argumentum ad hominem - "To the man." Use of personal attacks and insults to discredit or weaken an opponent's argument.
Burden of Proof (Appeal to Ignorance) - Description of Burden of Proof
Burden of Proof is a fallacy in which the burden of proof is placed on the wrong side. Another version occurs when a lack of evidence for side A is taken to be evidence for side B in cases in which the burden of proof actually rests on side B. A common name for this is an Appeal to Ignorance. This sort of reasoning typically has the following form:
1. Claim X is presented by side A and the burden of proof actually rests on side B.
2. Side B claims that X is false because there is no proof for X.
It is logical to assume that he created it because the one he got for his left hand (which he did not create) was kept and worn by the Massassi priest Zythmnr before Kun recovered it. If there was another amulet the Massassi would have kept it in similar conditions as the first, but they are not shown to have done so. Therefore, it is likely that Kun himself made it either from schematics he may have found or by simply copying the first one.
It is logical to assume it has identical properties to the first one until we have a logical premise to assume that it has different properties. We don't.
