INFANTRY TO HIT CALCULATION>>
In order for the attacker to hit, they must roll a number highter than the to hit calculation with a d10.
\[
\begin{indentalign}[2em][1em]{l}
(quadrant\ to\ hit + quadrant\ defense)\\ + (attacker\ raw\ movement - defender\ raw\ movement)\\ + (defender\ total\ defense + affinity\ bonus + (auxiliary\ boost + auxiliary\ affinity\ bonus))\\ - (attacker\ affinity\ bonus)\\ + (attacker\ tarrochi\ modifier - defender\ tarrochi\ modifier)\\ + (defender\ disorder\ modifier^{\color{red}*})\\ + (attacker\ tarrochi\ spirit\ effects - defender\ spirit\ effects)
\end{indentalign}
\]
*only applies to defender counterattack
Two infantry in light woods. The defender is a Chavero who has 2 total defense and is not in his affinity class, the attacker is a Mercamente, who receives an affinity bonus for his class. The attacker is supported by a support Papa, and the defender is supported by an auxiliary Fameio, who does not have an affinity bonus, adding 1 defense. Neither has strong tarrochi bonds. No Spirits are in effect. The defender disorder modifier only applies to counterattack, and is 1.
\[
\begin{indentalign}[2em][1em]{l}
(1+1)\\ + (2-2)\\ + (2+0+(1+0))\\-(1)\\ + (0-0)\\ + (0)\\ + (0-0)
\end{indentalign}
\]
\[2+0+3-1+0-0+0\]
The attacker only needs to roll above a 4 to hit.
ARTILLERY TO HIT CALCULATION>>
Artillery have their own to hit calculation.
\[
\begin{indentalign}[2em][1em]{l}
(quadrant\ to\ hit + quadrant\ defense)\\ - (defender\ raw\ movement)\\ + (defender\ total\ defense + affinity\ bonus + (auxiliary\ bonus+auxiliary\ affinity\ bonus))\\ - (attacker\ tarrochi\ modifier - defender\ tarrochi\ modifier)\\ - (attacker\ affinity\ bonus) - (defender\ disorder\ modifier^{\color{red}*})\\ + (attacker\ tarrochi\ spirit\ effects- defender\ tarrochi\ spirit\ effects)\\ + (adjacent\ quadrant\ penalty)
\end{indentalign}
\]
*only applies to defender counterattack
In the same circumstances as the previous example, no tarrochi mod, but with an affinity bonus, the artillery takes an adjacent quad modifier of 1.
\[
\begin{indentalign}[2em][1em]{l}
(1+1)\\ - (2)\\ + (2+0+(1+0))\\ - (0-0)\\ - (1) - (0)\\ + (0-0)\\ + (1)
\end{indentalign}
\]
\[
2-2+3-1-0+(0-0)+1
\]
The artillery only needs to roll above 5 to hit.
ASSETS that attack, such as cannons, have the same To Hit calculation, just with an added distance modifier for how many quads away they are, so if a cannon is attacking from 2 away, it would need to roll above 6.
DAMAGE CALCULATION>>
As in To Hit, the attacker must roll a d10.
In the same circumstance as in the earlier example, light woods provides 1 defense, the auxiliary Fameio of the defender does not play into calculation. An Attacker's damage is modified by a Support type unit, which the attacker has in a Support Papa, who gets an affinity bonus, providing an extra 2 to the calculation. The defending Chavero has a high base defense that adds to his class. Note in this calculation, disorder modifier does not play into actual damage.
\[
\begin{indentalign}[2em][1em]{l}
(quadrant\ def - quadrant\ atk)\\ + (attacker\ total\ attack + affinity\ bonus + (support\ bonus+support\ affinity\ bonus))\\ - (attacker\ tarrochi\ modifier - defender\ tarrochi\ modifier)\\ - (defender\ total\ defense + defender\ affinity\ bonus)\\ + (attacker\ tarrochi\ spirit\ effects- defender\ spirit\ effects)
\end{indentalign}
\]
\[
(1-0)+(1+1+2)-(0-0)-(3+0)+(0-0)
\]
The total damage done is 3 on hit.
The defending Chavero has a raw health of 3 and a class health of 3, so he is hardly out of the fight, and will return with back with the same calculations.
As this is a basic example, assuming low tarrochi bonds and no effects in play, these numbers don't indicate how everything might play out in a game, only provide a basic example of how the system works.
