Apparently in China peach wood (Along with the rest of the plant) is believed to have properties that repel evil spirits, a little similar to silver in European legends or iron for both European fae and West Asian/Middle eastern Jinn. Taoists sometimes keep swords made of peach wood because of this. This made me realize something. If you took a peach wood stick, and attached studs to it of both silver and iron you'd end up with a club or staff (or mace, flail etc.) that would have the weaknesses of many kinds of supernatural creatures while still retaining effectiveness as a normal weapon (peach is a hardwood and silver's poor edge retention doesn't matter for studs). You could even keep adding new stud materials to get something ridiculous that affects over 120 catalogued folkloric monsters. Since you just need a few little studs you could even get some really expensive materials like meteoric iron (a thumb tip sized meteorite can still cost like 10-20 bucks I think). I could somewhat feasibly make a weapon that affects every monster ever thought to walk the earth, from vampires and werewolves to jinn and jiangshi and even mankind.
