A known immortal traveling with the PCs kills an attacker, and is arrested and charged with murder, since immortals cannot kill in self defense, being immortal.
A large bamboo like plant grow on a shoreline. Rather than growing round like conventional bamboo, this type of grass is shaped more like celery, and mature stalks just need the ends trimmed for ready made canoes.
The players see a small shrine to the local nature deity just of the trail. Before they even approach it, they can smell the foul stench of rotting meat. If they inspect the shrine, they can see it has been desecrated by rotting organs in the last few days. There is no mistaking it for an obscure ritual, the organs are thrown everywhere, not left in specific places as in sacrifice.
If the players try to clean the shrine, they will soon find it has been boobytrapped to fling sharp splinters covered in the rotting gore in every direction. While only doing a few points of damage, they injured players will likely take sick soon unless they get medical attention.
As the players travel along the trail, they notice a bear in the woods, following thier moves. It does not make any agressive moves, but neither does it leave. As daylight fades, the players need to decide what to do. Is it a spirit guide, or gaurdian to the forest; is it a lycanthrope, or being controlled by evil spirits; or is it just a curious bear?
For those familiar with cantrips, you know they are minor acts of magic that have hardly any noticable effect on the world. For example a cantrip to make your food taste better won't heal you any more, or be any more nourishing, just won't make it so hard to get it down. A light cantrip certainly won't be able to blind or even distract anybody, but you might be able flash it to signal someone looking at the right spot.
What if children's nusery ryhmes were a form of cantrip? Like the "Rain, Rain, go away, come again another day." One child singing it wouldn't do more than spare her house a couple raindrops, but what if the whole village got together and was chanting in unison? Each one doing just a bit might actually be able to divert a whole storm...
A race of beings actually IS invunerable while in adolecence. They age, but cannot be killed. A miniority of the race (1 in 20) does not become invunerable, but rather becomes immortal at some point in thier adolecence, and ceases aging while being vunerable to death in all the normal ways. Another minority (also 1 in 20) Permanatly becomes invunerable after adolecence, but ages twice as fast as the race normally does. There is no known way to test for which of the three traits an individual manifests and the three traits cannot mix, as they are tied to the same gene, as it were.
A culture has a tradition of wearing animal pelts as a sign of status or job. Carpenters might wear beaver skins, Masons have a moleskin hood to their cloak, Gaurdsmen might have badger pelts. Done to show the culture's respect for nature and how much of nature is equal to each other.
A possible answer to what happens to spells when a mage dies. If the spell is strong enough, say and enchantment or other permenant effect, part of the mages spirit may become lodged in the magic. It may be a way for items to gain some kind of intelligence, but a mage who has knowledge of this fact would be very hesitant about enchanting anyone or thing. He might have other plans for his afterlife than counting the change in your bag of holding.
Preists, I think, would have this sort of thing covered.
A magician develops a new way to make scrolls and can sell more powerful spells for cheap. Problem is, whether the magician is aware of it or not, the spell's power comes from spirits trapped by the magic that makes the scroll. Once used to power the scroll, the spirit is driven mad by the forces that have ripped through it's being, and often develops a homicidal thirst to destroy the one who tormented it. The spell the spirit was used for may have left some residual power in the spirit to give it more abilities than it ever used to have.
A certain type of demon cannot not be hit by ranged weapons or attacks. Attacks have to be made up close and personal for the damage to mean something. Ranged attacks are to impersonal.
Possibally a way to make the ranged attacks more meaningful would be to coat the arrow head or what not with the shooters blood. Of course, they'd better be a good shot, otherwise they're wasting arrows and already bleeding to boot.
Spells: wizards might have half or no effect, preist might work due to divine intention.
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".
Hu was an ambassador of the Seventh Emperor of the Reng Dynasty. Throughout his life he traveled across many miles and lands to entreaty with neighboring kingdoms and the semi-savages who dwelled amidst the Metal Mountains.
During one such diplomatic mission, Hu was gifted a small iron marble as a gesture, by a shaman of the Kiy-Kiy tribe. Little else is known of Hu, but that marble was lost and is now somewhere out there for someone to find.
A tiny, shiny sphere, the marble has several properties. First and foremost it is a strong magnet, considerably stronger than its size and density would indicate.
Secondly, if thrown or rolled upon the ground and the command word is spoken, the iron ball will magically enlarge to either the size of an ogres's head or to that of a great globe, twelve feet in diameter. The rolling ball of either size will continue to roll or fly at the same relative speed it was when launched as a marble, and can thus cause great damage to anything in its path. The magnetic power of the ball will also magnify when enlarged.
Legends claim that the ball has been tossed from besieged castles upon attacking foes and rolled at marching armies in ages past. At the end of such rolls, the larger size globe has been known to not only crush soldiers underfoot, but to also "collect" many dozens of metallic weapons and bits of armor unto itself, appearing as an armored sphere, with swords and spears sticking out from it in all directions.
Owning this powerful marble has its drawbacks. Anyone carrying it on their person, will experience the iron ball's insidious effects after some time. The owner feels no worse for wear, but after two month's time they will suddenly awaken one morning to find that their hair has fallen out completely, their teeth loosened like baby's teeth ready to drop, and their fingernails simply shriveled and sliding off the fingers and toes. Perhaps unbeknownst to the owner at first, the iron ball also renders an owner sterile or barren by this time.
Regular clerical healing will not reverse this horrible malady. Only finding and beseeching a shaman of the Kiy-Kiy tribe to heal the iron ball's effects with their particular brand of magic, will work.
Hu's Iron Ball should be handled carefully by players and gms.
