Sign Language

Sign language is most frequently used by dwarves who were engaged in long running warfare with other dwarves or races. It permits silent communication with anyone who sees and understands the signals. The maximum range is usually line of sight in a lit area, or the extent of the receiver's infravision. Sign may be an extensive language capable of handling long conversations, or simply a means of communicating a few easy to understand phrases such as "attack," "orcs behind the rock," or "you three move left." A proficiency check is made when speaking or interpreting sign. The +2 bonus should only be used when giving short, easily recognized commands. More detailed signals require a -1 modifier.
