===== Combat system =====
~~NOTOC~~
==== Introduction ====
We use multi steps units. These units can take a certain number of hits.
A unit is only lost when all hits are taken: the unit will fight at full strength otherwise.
 
The combat system has the following phases:
  * Ranged phase (in parallel):
    * Ranged weapons
  * Melee phase (in parallel):
    * Attack
    * Defend

The ranged weapons, attack and defend are based on a modified d6 role.
This role is based on:
  * Unit base score
  * Modifier table
  * d6 role

The result of the role:
  * 14 or higher: 3 hits
  * 10 or higher: 2 hits (half of the hits of one standard unit)
  *  6 or higher: 1 hit

NOTE:
  - The modifier table is not based on the attacked unit (attack, defend and ranged role are independent of the other unit) .
  - The hits are not cumulative (a role of 15 is 3 hits not 3+2+1=6 hits).
  - If both units want to attack both will throw on the attack table. If both units defend nothing will happen.
  - For every unit a dice is roled. Hits are taken evenly by the units (Defender choice).
  - There is a stacking limit of 4 units.
  - When a raiding unit is attached to a combat unit, it gives a +1 bonus, both in defense as in offense.

==== Ranged modifier table ====
^ Effect ^ Modifier ^
| From wall | +#steps |
| To wall | -#steps |
| Moving to archers (attacker) | +1 |
| Undead | -1 |
==== Attacking modifier table ====
^ Affect ^ Modifier ^
| Wall | -#steps |
| Wood/city/bogs/hill | -1 |
| River | -2 |
| Dwarf hill | +1 |
| Magic | * |

==== Defender modifier table ====
^ Affect ^ Modifier ^
| Wall | +#steps |
| Wood/city/bogs/hill | +1 |
| River | +2 |

| Magic | * |
==== Walls ====

The outer wall
^ Strength ^ Steps ^ 
| 4        | 1     |
| 3        | 2     |
| 2        | 4     |
| 1        | -     |

The inner wall
^ Strength ^ Steps ^
| 3        | 1     |
| 2        | 3     |
| 1        | -     |

Walls can be damaged by:
  * Trebuchets
  * Dragons
  * Magic or its consequence as a colossus unit attaching the wall (as a trebuchet)

The last step of a wall cannot be removed.
So, strength 1 means that there are wide enough holes in the wall but some/most of it is still standing.
There will also be a lot of debris in these holes. You will have to walk carefully through these holes and you will also be vulnerable when walking through them.

==== Examples ====
The following sections show some examples of fights that could actual happen in 3 rounds.
=== Simple attack in the wood ===

The attacker has two infantry units attacking one infantry unit in the woods.

The attacker has a "-1" for attacking in the woods and the defender has a "+1".
This means that the attacker has a modifier of 4-1=3 and will hit on a 3-6.
The defender has a modifier of 4+1=5 and will hit on a 1-4 and will do 2 hits on a 5 or 6.
Initially all units have 4 steps.

^   ^ A1         ^^^ A2          ^^^ D1        ^^^ 
^   ^ D6 ^ Damage\\ inflicted ^ Steps\\ remaining ^ D6 ^ Damage\\ inflicted ^ Steps\\ remaining ^ D6 ^ Damage\\ inflicted ^ Steps\\ remaining ^
^ 1 |  1  |  0  |  3  |  5  |  1  |  4  |  2  |  1  |  3  |
^ 2 |  6  |  1  |  2  |  3  |  1  |  3  |  6  |  2  |  1  |
^ 3 |  Victory        ||||||  Retreat  |||

Before the last round of combat, the defender decided to retreat before losing his unit.
