Oriental Adventures on the class monk says
[T]he monk starts with proficiency in one style of unarmed combat and two of that style’s special maneuvers. The monk also has five other proficiency slots. Of these, one must be used for religion and another calligraphy. The remaining slots can be filled as the player sees fit within the restrictions of the class.” “All monks have the martial arts special maneuver Missile Deflection in addition to the other special maneuvers thay may have or gain. This is not considered part of any martial style and so does not use one of the special maneuver slots for the monk’s chosen martial art. (18)
And on the yakuza it says
Yakuza begin play with three proficiency slots available. In addition, they automatically have the gaming proficiency. (26)
Table 56 (Oriental Adventures 51) shows the proficiencies character classes gain when they advance levels except that the table omits the monk and the yakuza (51). What are these missing values?
The Player’s Handbook Weapon Proficiency Table and Unearthed Arcana show the following monk proficiences:
Class of Character | Initial # of Prof | Add Proficiency per Level | Non-proficiency Weapon Penalty Monk | 1 | 1/2 levels | -3
The Dungeoneer’s Survival Guide on Table 10 (23) and Wilderness Survival Guide on Table 1 (12) have the same proficiency entries for the monk:
Class of Character | Initial # of Proficiencies Weapon/Nonweapon | Add Proficiency per Level Weapon/Nonweapon Monk | 1/1 | 1/1 per 2 levels
However, using Oriental Adventures, it seems like for the monk and yakuza this information is as follows:
Class of Character | Initial # of Prof | Add Proficiency per Level | Non-proficiency Weapon Penalty Monk | 5 | missing (possibly 1/1 per 2 levels?) | -3 from PHB and UA Yakuza | 3 | missing | missing
…And I’d like to fill in the missing information.
