Monks and Assassins for Basic D&D

Most of the classes in classic D&D fit into a Tolkien-esque sort of campaign world, which in turn is largely based on northern european history and folklore. However over the years there have been a few character class options that suggest a campaign world with a more eastern flavour.

The Monk class was based on fighting monastic orders such as the Shaolin Temple, a Buddhist monastery in Henan province, China.  This style of Monk (or Nun if a female character) is quite different from the western religious orders who did not focus on physical training and hand-to-hand fighting techniques. While I like that the Monk offers more diversity in the implied setting, the implementation was messy. Lots of special abilities that are easy to forget, and special rules for advancement.

Similar to this was the Assassin class which was actually based on militant Islamic "monks" in Persia during the middle-ages. While the Shaolin Monks would dress in a manner making them easy to recognize the Ḥashshāshīn would travel in disguise and infiltrate neighbouring communities and rival kingdoms. They would then be able to eliminate key figures who might seek to move against their order.

In our continuing series of streamlined classes for Basic D&D I'm going to treat the Monks and Assassins as variants of each other, since they both represent eastern orders with fortified monasteries.

These classes are both based on the Cleric and are treated as such except as noted below. Due to the fantasy nature of the game they, like the Cleric, have been given fantastic abilities representing the folklore about them, rather than the historical truth of their orders.
