Homebrew Disc Trolls Species Details

Hail the king

Troll society is based on rocks and hitting people. They have numerous gods, all of whom bless their worshipers by hitting them on the head with a rock. Trolls believe in a heaven located underground, possibly because of a philosophizing troll's tendency to become part of the landscape. Troll courtships generally consist in the male troll hitting the female troll on the head with a suitably attractive rock followed after that by a candle lit dinner for two with a human as main course (although it is no longer considered polite to eat humans). Some female trolls, through contact with other races, have taken a more feminist approach to courting and now hit the males that they have chosen.

Troll society consists of numerous tribes, with frequent fights between them (although to trolls, this would be a spirited argument). They can only be united by a Diamond King.

One of the more sophisticated aspects of Trollish culture is their traditional view of time. As the past, where we have been, can be 'seen', whereas the future, where we are going, lies in front of us, they logically conclude we are going through time facing backwards. Also, since they are a nocturnal race, the trollish equivalent of the "Dawn of Time" is the "Sunset of Time."

Silicon life

Trolls are made of "metamorphorical rock" (a play on metamorphic rock and metaphorical), which means that trolls take on some of the appearance and characteristics of certain stones and minerals, after which they are usually named. Some trolls are made of sedimentary rock and trolls who have taken the forms of more solid minerals are sometimes prejudiced against their sedimentary kin. On very rare occasions, a troll made of diamond is born. These trolls are vastly more intelligent than most trolls, as their reflective bodies allow them to ward off heat and regulate their internal temperature. A diamond troll is the indisputable king of the trolls, whether it wants to be or not.

The common troll is nocturnal. Their natural tendency to spend daylight hours dormant led to the stories of them turning to stone when hit by the sun. Though apparently unintelligent, this is due to heat negatively affecting the conductivity of their silicon brains, which operate in a similar fashion to computer circuits. In the coldness of the high mountain areas that they usually call home, they can, in certain respects, be quite clever. When sufficiently deep-frozen, they can perform exceptional mathematical feats, possibly involving quantum computing. Oddly, the silicon-based trolls are capable of freezing to death if exposed to sufficiently cold temperatures, although such temperatures are far lower than fleshly creatures could survive.

Rock and stone is also the natural diet of trolls, and they have diamond teeth to enable this. Quartz is held to be unhealthy, as it "clogs the arteries", and ammonites are also avoided as a sign of the rock having gone stale. Trolls frequently use the word coprolite where a human would refer to fresher fecal matter; this may have a physiological analogue. They can gain some nutrition from the mineral content of carbon-based animals (including humans, although they never do that any more, honest), but not much.

Trolls often drink molten minerals for recreation. Due to the heat affecting their brains, this has the much same effect on them as alcohol does on humans. Electrolyte solutions have a similar effect, presumably more directly. One such drink is the Electrick Floorbanger. Troll "beer" is ammonium sulfide dissolved in alcohol.

Trolls are theoretically immortal, but as they get older they get bigger and slower and tend to be more inclined to sit and think. They call this "getting philosophy". Eventually they just stop moving altogether, gradually "decomposing" or eroding into an oddly-shaped heap of minerals with a tiny living spark in the center. Many of the Discworld's mountains are actually very old trolls. A prime example being 'old grand dad' who had grown so large that bandits have taken refuge in his mouth believing it to be a cave.

Their scientific or species name is Stultus Saxum (i.e. "Dumb Rock").

Troll Names

Trolls tend to be named after rocks, minerals and geological features, such as Detritus, Flint, Chrysoprase, and Mica, to name a few. Female trolls tend to be named for precious stones, such as "Jade" or "Ruby."

Disc Trolls Traits

Trolls share a number of traits in common with each other.

Silicone Brain

Troll brains are silicon-based and very susceptible to the heat and cold hence why trolls are often seen as rather dumb and simple because their brains are simply too hot in the temperate climate of cities.
ask your DM about the weather

advantage to intelligence checks and saves in cold climate
disadvantage to intelligence checks and saves in warm climate

Ability Score Increase

Your Strength score increases by 2, your Constitution score increases by 1, and your intelligence score decreased by 2

Age

Trolls are semi immortal but will increasingly stop to settle down to think as they get older around 500 years until they one day stops altogether and becomes one with the landscape . They enter adulthood around 25 years.

Diamond teeth

Trolls are equipped with a set of shiny diamond teeth and a bite strong enough to crush stone and other minerals.

Alignment

Troll society is based around rocks and hitting people and thus chaotic in nature. the Diamond King of trolls is the only one that can unite all the clans and speaks for all trollkind.
recently many city trolls have adapted to the laws of humans and other generally civilized ways of living.
