Hit Dice to Hits
for light/heavy/armored foot/light horse the conversion is 1:1

example: Giants in D&D range in size from 8HD (hill giant) to 16 HD (titan) with the average being 12HD. this is the same in CHAINMAIL with the default giant attacking as 12 heavy foot.

for medium horse the conversion is 1:2 and for heavy horse the conversion is 1:3 (what it takes for an armored foe to kill them) 9HD red dragon defends and attacks as 3 heavy horse. Dragons range in size from 1-6 heavy horse (4-24 hits from light foot, or 3-16 hits from armored foot). Reds range from 3-4 heavy horse, or 9-12HD

The hero requires 14 points of simultaneous damage in a round to drive him off the board. The troll requires 21 cumulative hits. Creatures with multiple d6 damage may attack separate targets up to the number of dice that they have (a hero may kill up to 4 units of goblins per round). If you introduce cleric heroes, you may wish to convert heroes from simultaneous hits to cumulative.
