The vampire ring is a magic weapon, which is necessary for the plot.
The six-pointed star symbol is an ordinary prop. You may not have a chance to hit the preacher, but you can steal it as long as he plays in the battle. How many times have I forgotten? It seems to be three times. Anyway, BOSS can steal good things, just one. Does not affect the chances of getting props after the battle. Another way is to use the practice instructions of cinnabar magic pen, and there is blank symbol paper on your body. If you use it on missionaries, you can get one after the battle.
So if you are lucky, you can take three at a time.
The six-pointed star symbol is useless, just a collection. Can we use a hexagonal star array? On the whole, hehe, it's still slashing.
