Some of you may know I made a set of weapon cards for the 1981 Classic Traveller. Each card lists a specific weapon, the +/-DMs for Strength or Dexterity, and a matrix that combines the DMs for range and armor from Book 1 into a single Throw number.
Here is an example of how the matrix works:
1. The DM for SMG against No Armor is +5.
2. The DM for SMG against the five ranges (as you note) are -4 +3 +3 -3 -9
3. When we combine these two DMs (which is what the Weapon Card matrix does) for No Armor at the five ranges, we get +1 +8 +8 +2 -4
4. We then applied these five DMs (which combine the DMs for range and armor) to the required hit roll of 8+
5. The final numbers printed on the card represent what the Player needs to roll or better on 2D6. So: No armor, close range is DM +1, meaning the PC needs to roll a 7+.
In this way, the Player only has to look down at the card and read the Throw number required.
I now have a set of the cards for the 1977 edition of Traveller. The big difference is the damage values. In the 1981 edition of the game all damage values are whole dice (xD6). In the 1977 edition of the game some of the damage rolls are modified by a +/-DM (xD6 +/-y).
Here’s an example of the card in action:
The character needs to Throw the number in the matrix or higher to hit (excluding other DMs of course.)
In the notation above the character has a Blade-5 expertise and a DM +1 because of his Strength of 9+, and so he has a DM +6 when using blade. A character with melee weapon expertise can apply that expertise as a -DM to incoming melee attacks, thus the parry value of 5, for a DM -5 if someone attacks him with a melee weapon while he is defending with his Blade.
You can print the cards out, cut them pages into quarters, and hand a card to any Player with a PC carrying a given weapon. (I printed them on a heavier card stock, using pre-perforated sheets used for name tags. Each weapon card sheet divides neatly into equal quarters.)
As always, if you spot any errors let me know!
