Upon reaching 9th level, a Neutral traveling fighter may elect to become a Ranger. The following requirements must be met:
The character must live in a wild location. Rangers do not live in cities and they rarely visit them. Rangers will occasionally pay visits to the nearby village for supplies and to sell furs, or whatever necessary to maintain contact with rural humans. Rangers must do whatever they can to protect their chosen homeland and the people that live there.
If the ranger’s Wisdom score is 13, or greater, the character can cast druid spells as if he were a druid of one-third his actual experience level (round any fractions down); if a fighter becomes a ranger right at 9th level, he’ll immediately gain the spells of a 3rd level druid. A 17th level ranger can cast spells as if he were a 5th level druid.
A ranger may only travel with a number of hirelings equal to, or less than, his druid level. In other words, if he can cast spells as a 5th level druid, he can have five hirelings accompany him.
Rangers can Move Silently and Hide in Shadows as a thief of one-third his actual experience level (round any fractions down.) Rangers can also Find and Remove Traps as a thief of one-third his actual experience level, but only in a woodland environment.
