Analysis of HeroScape

The total number of possible results of a set of events is equal to the number of outcomes for the first event multiplied by the number of outcomes for the second event, the result of the previous calculation multiplied by the number of outcomes for the third event, and so on for each of the events. The result of the last multiplication is the total number of results. So if X is the number of outcomes of the first event, Y is the number of outcomes of the second event, and Z is the number of outcomes of the third event, the total number of possible results for the set of events (X, Y, Z), is X x Y x Z.



Each die represents a separate event. The attack and defense dice have six sides. Thus, the total number of results is equal to 6 to the power of the number of dice that are being rolled. The following table lists the total number of results for 2 through 13 dice.
6x6 =36
6x6x6 =216
6x6x6x6 =1296

In HeroScape only a small fraction of the results on the die represent hits or blocks. If we wanted to calculate the total number of results of a set of dice that consisted solely of blocks we would take the number of blocks on each die to the power of the number of dice that are rolled. The following table lists the total number of such results for 2 through 13 dice.
2x2 =4
2x2x2 =8
2x2x2x2 =16
2x2x2x2x2 =32
2x2x2x2x2x2 =64
2x2x2x2x2x2x2 =128
2x2x2x2x2x2x2x2 =256
2x2x2x2x2x2x2x2x2 =512
2x2x2x2x2x2x2x2x2x2 =1024
2x2x2x2x2x2x2x2x2x2x2 =2048
2x2x2x2x2x2x2x2x2x2x2x2 =4096
2x2x2x2x2x2x2x2x2x2x2x2x2 =8192


Similarly, if we wanted to calculate the total number of results of a set of dice that consisted solely of hits we would take the number of hits on each die to the power of the number of dice that are rolled. The following is a table of such calculations.
3x3 =9
3x3x3 =81
3x3x3x3 =256
3x3x3x3x3 =243
3x3x3x3x3x3 =729
3x3x3x3x3x3x3 =2187
3x3x3x3x3x3x3x3 =6561


Similarly, if we wanted to calculate the total number of results of a set of dice that consisted solely of misses we would take the number of misses on each die to the power of the number of dice that are rolled. The following is a table of such calculations.
4x4 =16
4x4x4 =64
4x4x4x4 =256
4x4x4x4x4 =1024
4x4x4x4x4x4 =4096
4x4x4x4x4x4x4 =16384
4x4x4x4x4x4x4x4 =65536
4x4x4x4x4x4x4x4x4 =262144
4x4x4x4x4x4x4x4x4x4 =1048576
4x4x4x4x4x4x4x4x4x4x4 =4194304
4x4x4x4x4x4x4x4x4x4x4x4 =16777216
4x4x4x4x4x4x4x4x4x4x4x4x4 =67108864


For example, the number of results of two dice consisting of 2 shield blocks is equal to the number of blocks on each die multipled together (or 2 (the number of shields) to the second power (the number of dice)). The result is 4. To calculate the percentage of the total number of possibilities we would divide this result by 36. The result is 11.111%.

If we wanted to calculate the number of 1 shield blocks on two dice we would multiply the number of blocks on one die by the number of misses on the other. We also need to consider all the unique permutations of the dice. The number of permutations is equal to n! (where n is the number of dice that are being rolled) Thus, for two dice there are two permutations. We multiply the initial result by the number of permutations. The sum of the two results divided by the total number of possibilities gives us the percentage of hits. ((Blocks x Hits) x n!)/ Number of Possibilities = Percentage
((2 x 4) x 2)/ 36 = 44.444%

When rolling more dice the consideration of the number of possibilities is somewhat more complex. The number of permutations of a set of numbers where some of the numbers may be equal is equal to n!/m! x o! ... (where n is the number of dice that are being rolled) (m is the number of dice with a particular result and o is the number of dice with a different particular result) For example if we were rolling for dice and wanted to calculate the number of results consisting of two shields, We would multiply (2 x 2 x 4 x 4) x (24/(2 x 2))/1296=
(64 x 6)/1296 = 29.62963%

We may learn all kinds of things about the game from these statistics.

All of the defense distributions are skewed to the left, i.e. they favor rolling fewer shields. One can also see how unlikely it is to roll many shields. The attack distributions on the other hand are symmetrical, i.e. you are equally likely to roll all skulls or no skulls. The defense distribution is skewed to the extent that an attack of 3 dice ends up having a higher average than a defense of 4 dice. As the number of dice increase this skewing favors attacking even more.

Given that the game favors attacking, it is important to attack first. The charts also illustrate the importance of rolling an extra die. Given that you can roll an extra die for being on a higher level than your opponent, taking a high position is very important.

We may wish to calculate the joint occurence of two events. In such an instance multiply the probability of event 1 with that of event 2. The result will be much smaller than the probabilities of the separate events.

We may wish to determine whether it is more advantagous to attack first, or to seek higher ground. To do this we need to compare the odds of wounding our opponent in both scenarios. If both characters had 3 attacks and 4 defense and we attack first, the odds of wounding our opponent are 38.93%. (This is calculated by multiplying the percentage of a higher attacking result by that of a lower defending result for all such results, and summing the results) If we seek higher ground and attack second (we now have 4 attacks and 5 defense), the unmodified odds of wounding our opponent would be 53.72%. However, our opponent attacks first. The odds of being wounded are 30.70%. Thus, the odds of wounding are equal to 53.72% of 69.7% (the remaining) which is 37.44284% Thus, we see that in this circumstance attacking first is the better option. In the case of an attack 3, defense 6 character versus a 3/4 character, heading for higher ground is the better option.

The odds of an attack 3 figure wounding an Izumi Samurai in close combat are slightly less than the odds of the Izumi Samurai wounding the character in the process.

The odds of an attack 3 figure wounding a Deathwalker are less than 1 in 10.



The Horde Strategy

A squad of four characters will result in at least 10 attacks, as the following chart illustrates

4 attacks versus 1 attack
3 attacks versus 1 attack
2 attacks versus 1 attack
1 attack versus 1 attack
Total Attacks
10 versus 4

A squad of three characters will result in at least 6 attacks. Here the difference between three and four characters ganging up on a character is made clear, as 10 attack is almost double 6 attacks. Obviously not more than 6 characters can gang up on a single normal sized character in hand to hand combat.

If a character with attack 3 fought a character with defense 4 38.93% of the attacks would wound the opponent.
3 attack vs 4 defense
.37x.19=.0703
.37x.39=.1443
.37x.19=.0703
.12x.29=.0348
.12x.39=.0468
.12x.19=.0228

In 10 such attacks we can expect to have 3.893 successful attacks. Each one of these will give at least 1 wound. There is about a 15% chance that an attack will result in 2 or 3 wounds being dealt. That is more than enough to kill Agent Carr or Sgt. Alexander. In 6 attacks we can expect at least 2.3358 successful attacks.

One of the difficulties in the horde strategy is utilizing all of your figures. There generally are so many that most will not have a chance to attack. It is much easier to get the figures into combat if they have a ranged attack. This allows even more than 6 figures to attack a single opponent at once. Thus, taking ranged figures is important in horde strategy.
