freyar said:That all make sense to me. Do we want to give them a special ability that they treat all bows as masterwork (to get the +1 to attack)?
The nomadic centaurs speak their own tribal tongue, although most tribes in a large region speak a dialect of the same tongue. Very few know any other language. Common is the most frequent second language.
Traditionally, nomadic centaurs use a shortbow (with quivers of 100 arrows), light lance, and saber. Some (no more than 15 percent) use small shields. They are masters of the bow, trained to shoot from childhood. They gain a +1 on their THAC0 when using a bow.
They can move their normal movement and shoot an arrow at the same time, without any penalty.
The bow plays an important role in the centaur style of combat. They try to avoid straight-up fights whenever possible, since this deprives them of their two biggest advantages--speed and range. Instead they will keep a distance from the enemy, firing arrows and then galloping out of the way when the enemy charges. Among their own, they say that a warrior who fights with a sword is either a hero, an incompetent, or a fool.
Although they can use their hooves to kick, the nomadic centaur warriors disdain this tactic. Such methods are used only by old females and the sick.
Habitat/Society: Nomadic centaurs are aloof, proud creatures. They are very tribal, each centaur belonging to a particular clan of a particular tribe. A clan averages 11 to 30 (1d20 + 10) individuals. A tribe is made up of 2 to 12 clans. Each clan travels and hunts as a separate group. Sometimes two or more clans will band together to make a raid or defend against raiders, but such unions last only as long as there is a need.
The ratio of females to males is two to one. Only males go on raids or hunt, yet females are equally skilled in combat and will fight to defend the clan. The young (1-2 hit dice) are fiercely protected but will fight with hooves and bows if necessary (1-3 points of damage, no bonus to THAC0 when using the bow). There are 3 to 18 young per clan, but never more than 50% of the total clan. In addition, each clan keeps a small herd of horses.
Treasures taken by the clan are communally held. They recognize and understand the value of magical items. Those they can use, particularly weapons, are distributed among the warriors.
Although the centaurs have no particular love of nature, they have learned how to manage it. Wells are carefully maintained, and little water is wasted. Before an area is over-hunted, centaurs will move their hunting ground. They do not hunt for sport, and little of their kills go to waste. They make few demands on the land, thus ensuring there will be adequate resources for the future.
