Stellagama Publishing has released a new rules supplement for Classic or Mongoose Traveller, although for reasons of copyright it doesn't say that directly. Instead, it points to the Cepheus Engine OGL rules set. This booklet brings to my mind the article from the old Journal of the Travellers' Aid Society “Medical Treatment in Traveller”, although the emphasis is different.
What is it?
From the Ashes (FtA) is an optional rules package, concerning mortal injuries to characters and their effects, should the character survive. Two sections discuss replacement of damaged or destroyed body parts with prostheses or cybernetics.
What format is it?
It's in .pdf format, 15 pages.
What can I do with it?
MgT uses nuanced interpretation of task rolls, with regular break points when a task throw misses or exceeds the target by so much. With CT, it's simply roll for the target number and succeed/fail. If the referee wants to apply effects relating to 'just made it' or 'made it by a mile' he can but it is all at the referee's discretion. The FtA rules apply particular results to all surgery and recovery throws; sometimes making the target number still isn't good enough. Yes you succeeded, but . . . Well, medical care is a tricky thing. The FtA rules reflect that well, and continue to keep Traveller at least in spitting distance of reality.
Scars and other physical marks can be a way of distinguishing the PC, and helping the players visualize their characters. In the right circs a scar could help a PC influence an NPC by intimidation or impressive storytelling. The potential for large complications may also encourage even trigger-happy players to try more negotiation and social-skills roleplaying over solving all your problems with a gun.
