sfchbryan: where are you seeing these DMs?
Zhodani, first thoughts (skills):
Because of the different culture and psychology of the Zhodani, the basic MegaTraveller rules (written to apply to the typically human Imperium) need certain alterations and changes to accommodate the alien Zhodani. Where not specifically changed in Alien Module 4 - Zhodani, the standard MegaTraveller rules apply; where changes are provided in this document, they apply instead.
SKILLS
The skills presented here are, for the most part, identical to those available in MegaTraveller. Two added skill in AM4, Liaison and Trader, exist in MegaTraveller and are used from there. One added skill in AM4, Non-Verbal Communication, is part of the Interview skill in MegaTraveller, and the functions of the Psychology skill from AM4 are subsumed by the Interpersonal tasks system in MegaTraveller.
Rare Skills: Six skills from MegaTraveller are not ordinarily permitted to Zhodani characters—Bribery, Disguise, Forgery, Gambling, Intrusion, and Streetwise.
Interpersonal Skills: For tasks involving interactions between Zhodani and other humans, increase the task difficulty by one level unless the individuals are known to each other.
