“ Mining in a certain area turns all exposed skin (maybe just parts that are actively disturbing the chemicals that cause the reaction) of the those doing the mining to a dark blue color. Will wear off taking as many years/days spent in the mine.”
“ These little beetles have heads at both ends of their bodies. This allows them to feed on leaves at twice the rate of their normal cousins, causing great damage to crops. They look like ladybugs more than actual beetles, but have no wings. They have a funny way of moving if one stops to watch them, as both heads seem to vie for picking the direction at any given time. Their favorite nourishment is sugar cane. After feasting on these for some time, they develop short bursts of frenetic energy, and can be seen racing back and forth without purpose, which looks quite comical to onlookers. They are otherwise normal bugs. Of course the pc's might not know that.”
“ Weapons or equipment that is heavily relied on can be 'named'. Then the equipment begins to gain abilities beyond those of normal equipment. They might siphon off some of the experiances of their owners (1 to 5%) and level up on thier own. Could be an unintenitional way of creating artifacts. Ships could become sturdier or seem to just barely outrun the worse of a storm that would have surely sunk another vessle, swords could fumble less or resist dulling more, a farmers plow could turn stones aside easier. Anything that is depended on as much as an inividual can depend on as much as another individual could be 'named'.”
