Below is an excert from the Players handbook on a Ranger.
Ability Requirements: Strength 13
Prime Requisites: Strength, Dexterity, Wisdom
Races Allowed: Human, Elf, Half-elf
The ranger is a hunter and woodsman who lives by not only his sword, but also his wits. Robin Hood, Orion, Jack the giant killer, and the huntresses of Diana are examples of rangers from history and legend. The abilities of the ranger make him particularly good at tracking, woodcraft, and spying.

The ranger must have scores not less than 13 in Strength, 14 in Constitution, 13 in Dexterity, and 14 in Wisdom. The prime requisites of the ranger are Strength, Dexterity, and Wisdom. Rangers are always good, but they can be lawful, neutral, or chaotic. It is in the ranger's heart to do good, but not always by the rules.
A ranger who has Strength, Dexterity, and Wisdom scores of 16 or more gains a 10% bonus to the experience points he earns.
Although the ranger can use any weapon and wear any armor, several of his special abilities are usable only when he is wearing studded leather or lighter armor.
Although he has the basic skills of a warrior, the ranger also has several advantages. When wearing studded leather or lighter armor, a ranger can fight two-handed with no penalty to his attack rolls (see "Attacking with Two Weapons" in Chapter 9: Combat). Obviously, the ranger cannot use a shield when fighting this way. A ranger can still fight with two weapons while wearing heavier armor than studded leather, but he suffers the standard attack roll penalties.
The ranger is skilled woodsman. Even if the optional proficiency rules are not used, the ranger has tracking proficiency. If the proficiency rules are used in your campaign, the ranger knows tracking without expending any points. Furthermore, this skill improves by +1 for every three levels the ranger has earned (3rd to 5th level, +1; 6th to 8th level, +2, etc.). While wearing studded leather or lighter armor, the ranger can try to move silently and hide in shadows. His chance to succeed in natural surroundings is given on Table 18 (modified by the ranger's race and Dexterity, as given on Tables 27 and 28). When attempting these actions in non-natural surroundings (a musty crypt or city streets) the chance of success is halved. Hiding in shadows and moving silently are not possible in any armor heavier than studded leather--the armor is inflexible and makes too much noise.
In their roles as protector of good, rangers tend to focus their efforts against some particular creature, usually one that marauds their homeland. Before advancing to 2nd level, every ranger must select a species enemy. Typical enemies include giants, orcs, lizard men, trolls, or ghouls; your DM has final approval on the choice. Thereafter, whenever the ranger encounters that enemy, he gains a +4 bonus to his attack rolls. This enmity can be concealed only with great difficulty, so the ranger suffers a -4 penalty on all encounter reactions with creatures of the hated type. Furthermore, the ranger will actively seek out this enemy in combat in preference to all other foes unless someone else presents a much greater danger.
Rangers are adept with both trained and untamed creatures, having a limited degree of animal empathy. If a ranger carefully approaches or tends any natural animal, he can try to modify the animal's reactions. (A natural animal is one that can be found in the real world -- a bear, snake, zebra, etc.)
When dealing with domestic or non-hostile animals, a ranger can approach the animal and befriend it automatically. He can easily discern the qualities of the creature (spotting the best horse in the corral or seeing that the runt of the litter actually has great promise).
When dealing with a wild animal or an animal trained to attack, the animal must roll a saving throw vs. rods to resist the ranger's overtures. (This table is used even though the ranger's power is non-magical.) The ranger imposes a -1 penalty on the die roll for every three experience levels he has earned (-1 at 1st to 3rd, -2 at 4th to 6th, etc.). If the creature fails the saving throw, its reaction can be shifted one category as the ranger chooses. Of course, the ranger must be at the front of the party and must approach the creature fearlessly.
For example, Beornhelm, a 7th-level ranger, is leading his friends through the woods. On entering a clearing, he spots a hungry black bear blocking the path on the other side. Signaling his friends to wait, Beornhelm approaches the beast, whispering soothing words. The DM rolls a saving throw vs. rods for the bear, modified by -3 for Beornhelm's level. The bear's normal reaction is unfriendly, but Beornhelm's presence reduces this to neutral. The party waits patiently until the bear wanders off to seek its dinner elsewhere.
Later, Beornhelm goes to the horse market to get a new mount. The dealer shows him a spirited horse, notorious for being vicious and stubborn. Beornhelm approaches it carefully, again speaking soothingly, and mounts the stallion with no difficulty. Ridden by Beornhelm, the horse is spirited but well-behaved. Approached by anyone else, the horse reverts to its old ways.
A ranger can learn priest spells, but only those of the plant or animal spheres (see "Priest" later in this chapter), when he reaches 8th level (see Table 18). He gains and uses his spells according to the rules given for priests. He does not gain bonus spells for a high Wisdom score, nor is he ever able to use priest scrolls or magical items unless specially noted otherwise.
Rangers can build castles, forts, or strongholds, but do not gain any special followers by doing so.
At 10th level, a ranger attracts 2d6 followers. These followers might be normal humans, but they are often animals or even stranger denizens of the land. Table 19 can be used to determine these, or your DM may assign specific followers.
01-10 Bear, black
11-20 Bear, brown
22-26 Cleric (human)
51-53 Fighter (elf)
54-55 Fighter (gnome)
56-57 Fighter (halfling)
58-65 Fighter (human)
66 Fighter/mage (elf)*
67-72 Great cat (tiger, lion, etc.)*
76-80 Ranger (half-elf)
81-90 Ranger (human)
96 Thief (halfling)
97 Thief (human)
00 Other wilderness creature (chosen by the DM)
*If the ranger already has a follower of this type, ignore this result and roll again.
Of course, your DM can assign particular creatures, either choosing from the list above or from any other source. He can also rule that certain creatures are not found in the region -- it is highly unlikely that a tiger would come wandering through a territory similar to western Europe!
These followers arrive over the course of several months. often they are encountered during the ranger's adventures (allowing you and your DM a chance to role-play the initial meeting). While the followers are automatically loyal and friendly toward the ranger, their future behavior depends on the ranger's treatment of them. In all cases, the ranger does not gain any special method of communicating with his followers. He must either have some way of speaking to them or they simply mutely accompany him on his journeys. ("Yeah, this bear's been with me for years. Don't know why--he just seems to follow me around. I don't own him and can't tell him to do anything he don't want to do," said the grizzled old woodsman sitting outside the tavern.)
Of course, the ranger is not obligated to take on followers. If he prefers to remain independent, he can release his followers at any time. They reluctantly depart, but stand ready to answer any call for aid he might put out at a later time.
Like the paladin, the ranger has a code of behavior.
A ranger must always retain his good alignment. If the ranger intentionally commits an evil act, he automatically loses his ranger status. Thereafter he is considered a fighter of the same level (if he has more experience points than a fighter of his level, he loses all the excess experience points). His ranger status can never be regained. If the ranger involuntarily commits an evil act (perhaps in a situation of no choice), he cannot earn any more experience points until he has cleansed himself of that evil. This can be accomplished by correcting the wrongs he committed, revenging himself on the person who forced him to commit the act, or releasing those oppressed by evil. The ranger instinctively knows what things he must do to regain his status (i.e., the DM creates a special adventure for the character).
Furthermore, rangers tend to be loners, men constantly on the move. They cannot have henchmen, hirelings, mercenaries, or even servants until they reach 8th level. While they can have any monetary amount of treasure, they cannot have more treasure than they can carry. Excess treasure must either be converted to a portable form or donated to a worthy institution (an NPC group, not a player character).
The wizard group encompasses all spellcasters working in the various fields of magic--both those who specialize in specific schools of magic and those who study a broad range of magical theories. Spending their lives in pursuit of arcane wisdom, wizards have little time for physical endeavors. They tend to be poor fighters with little knowledge of weaponry. However, they command powerful and dangerous energies with a few simple gestures, rare components, and mystical words.
Spells are the tools, weapons, and armor of the wizard. He is weak in a toe-to-toe fight, but when prepared he can strike down his foes at a distance, vanish in an instant, become a wholly different creature, or even invade the mind of an enemy and take control of his thoughts and actions. No secrets are safe from a wizard and no fortress is secure. His quest for knowledge and power often leads him into realms where mortals were never meant to go.
Wizards cannot wear any armor, for several reasons. Firstly, most spells require complicated gestures and odd posturings by the caster and armor restricts the wearer's ability to do these properly. Secondly, the wizard spent his youth (and will spend most of his life) learning arcane languages, poring through old books, and practicing his spells. This leaves no time for learning other things (like how to wear armor properly and use it effectively). If the wizard had spent his time learning about armor, he would not have even the meager skills and powers he begins with. There are even unfounded theories that claim the materials in most armors disrupt the delicate fabric of a spell as it gathers energy; the two cannot exist side by side in harmony. While this idea is popular with the common people, true wizards know this is simply not true. If it were, how would they ever be able to cast spells requiring iron braziers or metal bowls?
For similar reasons, wizards are severely restricted in the weapons they can use. They are limited to those that are easy to learn or are sometimes useful in their own research. Hence, a wizard can use a dagger or a staff, items that are traditionally useful in magical studies. Other weapons allowed are darts, knives, and slings (weapons that require little skill, little strength, or both).
Wizards can use more magical items than any other characters. These include potions, rings, wands, rods, scrolls, and most miscellaneous magical items. A wizard can use a magical version of any weapon allowed to his class but cannot use magical armor, because no armor is allowed. Between their spells and magical items, however, wizards wield great power.
Finally, all wizards (whether mages or specialists) can create new magical items, ranging from simple scrolls and potions to powerful staves and magical swords. Once he reaches 9th level, a wizard can pen magical scrolls and brew potions. He can construct more powerful magical items only after he has learned the appropriate spells (or works with someone who knows them). Your DM should consult the Spell Research and Magical Items sections of the DMG for more information.
No matter what school of magic the wizard is involved in, Intelligence is his prime requisite (or one of several prime requisites). Characters must have an Intelligence score of at least 9 to qualify to be a wizard.
All wizards use Table 20 to determine their advancement in level as they earn experience points. They also use Table 21 to determine the levels and numbers of spells they can cast at each experience level.
All wizards gain one four-sided Hit Die (1d4) per level from 1st through 10th levels. After 10th level, wizards earn 1 hit point per level and they no longer gain additional hit point bonuses for high Constitution scores.
