CT/MgT <-> D20

[Nathan Brazil]

Size: The Core Rules has Alien Traits of Small and Large. Some are called Tiny, so small that they provide a -1DM to be hit. Some are so Large as to be called Huge and get a +1 to be hit. Finally some things are so big, like starships, and have which receive a +4 to be hit. I forgot the page reference about the starships at the moment. We are only talking about being hit. Not if the hit penetrates. It seems that my DC to DM conversion chart still can be applied:

SRD         DC     Traveller DM
?          +10     Starship  +4
Colossal    +8     ?         +3
Gargantuan  +4     ?         +2
Huge        +2     Huge      +1
Large       +1     Large     +0
Medium      +0     ?         +0
Small       -1     Small     +0
Tiny        -2     Tiny      -1
Diminutive  -4     ?         -2
Fine        -8     ?         -3

Again, the ? means that the rulebook does not have a descriptive world for the associated value.

3.Because of this, it seems that each +5/-5 from the DC relates to a +2/-2 in Traveller Which means that you can convert bonuses back and forth:
D20 to Traveller
DC DM
+1 +0
+2 +1
+3 +1
+4 +2
+5 +2
+6 +2
+7 +3
+8 +3
+9 +4
+10 +4

Thanks for the conversion. My players want me to convert MGT to a semi-D20 format (along with other stuff). So I'm rewriting using the SRD's.
