I have been pondering how to modify combat impact results for opponents of differing sizes and have come up with the following solution. I would welcome thoughts and comments.
HM4.0 Combat Matrix.doc
The way I imagine this working is that combatants would be placed in a size category and the number of size ranks between them would be counted. Then each would use the appropriate line on the Injury table for injuries to their opponent. Thus, a Lynx sized creature fighting a bear sized creature would be 4 size ranks down (and so to the other way around). Any damage by the "lynx" on the "bear" would be along the -4 line and that of the "bear" on the "lynx" on the +4 line. And so a 11 impact strike by the smaller would result in an M1 while the same impact by the larger would cause a K5.
In addition, I am accounting for the different severity to various zones of the anatomy by having adds to the size rank: -1 for limbs, plus 1 for abdomen and +2 for head. Thus, in the previous example, if the smaller combatant struck the head with that same 11 impact, we would read up two rows to arrive at an S2 on its much larger opponent.
The last consideration I have is modifying AML/DML. It seems to me that a smaller opponent might have an easier time hitting a larger (but do less damage) while a larger could have a more difficult time hitting a smaller (but what a whollop when they hit...). SO a smaller opponent gets bonuses against a larger. I think this variance should be considerable when we have a huge difference in size....
So, what do you all think?
