The [unit_type] tag

Each [unit_type] tag defines one unit type. (for the use of [unit] to create a unit, see SingleUnitWML)

Unit animation syntax is described in AnimationWML.

The following key/tags are recognized:

After max level advancement (AMLA)

  • [advancement]: describes what happens to a unit when it reaches the XP required for advancement. It is considered as an advancement in the same way as advancement described by advances_to; however, if the player chooses this advancement, the unit will have one or more effects applied to it instead of advancing.
    • always_display: if set to true displays the AMLA option even if it is the only available one.
    • description: a description (see DescriptionWML) displayed as the option for this advancement if there is another advancement option that the player must choose from; otherwise, the advancement is chosen automatically and this key is irrelevant.
    • image: an image to display next to the description in the advancement menu.
    • max_times: default 1. The maximum times the unit can be awarded this advancement.
    • strict_amla: (yes|no) default=no. Disable the AMLA if the unit can advance to another unit.
    • require_amla: An optional list of AMLA id keys that act as prerequisites for this advancement to become available. Order is not important, and an AMLA id can be repeated any number of times to indicate that another advancement must be chosen several times before this advancement option will become available.
      • example: require_amla=tough,tough,incr_damage assumes there exist other [advancement] options called id=tough and id=incr_damage. Once tough is chosen twice and incr_damage is chosen once, then the current [advancement] will become available.
      • require_amla=tough,incr_damage,tough is an equivalent way of expressing this.
    • [effect]: A modification applied to the unit whenever this advancement is chosen. See EffectWML


  • [attack]: one of the unit's attacks.
    • description: a translatable text for name of the attack, to be displayed to the user.
    • name: the name of the attack. Used as a default description, if description is not present, and to determine the default icon, if icon is not present (if name=x then icon=attacks/x.png is assumed unless present). Non-translatable. Used for the has_weapon key and animation filters; see StandardUnitFilter and AnimationWML
    • type: the damage type of the attack. Used in determining resistance to this attack (see [resistances], UnitsWML).
    • [specials]: contains the specials of the attack. See AbilitiesWML.
    • icon: the image to use as an icon for the attack in the attack choice menu, as a path relative to the images directory.
    • range: the range of the attack. Used to determine the enemy's retaliation, which will be of the same type. Also displayed on the status table in parentheses; 'melee'(default) displays "melee", while 'ranged' displays "ranged". Range can be anything. Standard values are now "melee" and "ranged". From now on, short and long will be treated as totally different ranges. You can create any number of ranges now (with any name), and units can only retaliate against attacks for which they have a corresponding attack of the same range. This value is translatable.
    • damage: the damage of this attack
    • number: the number of strikes per attack this weapon has
    • movement_used: determines how many movement points using this attack expends. By default all movement is used up, set this to 0 to make attacking with this attack expend no movement.

For those two following settings, the engine usually chooses the attack with the best average total damages * weight (default weight = 1.0).

    • attack_weight: helps the AI to choose which attack to use when attacking; highly weighted attacks are more likely to be used. Setting it to 0 disables the attack on attack
    • defense_weight: used to determine which attack is used for retaliation. This affects gameplay, as the player is not allowed to determine his unit's retaliation weapon. Setting it to 0 disable the attacks on defense


See AnimationWML for details on how to specify animations for the unit.

Other tags

  • [base_unit]: Contains one attribute, id, which must be the ID of a unit type. If specified, the UnitTypeWML for that unit is copied into this one. Subsequent attributes modify the copy. (1.3.7 and later versions only.)
  • [abilities]: Defines the abilities of a unit. See AbilitiesWML
  • [event]: Any [event] written inside the [unit_type] tag will get included into any scenario where a unit of this type appears in. Note that such events get included when a unit of this type first appears in the scenario, not automatically when the scenario begins (meaning that name=prestart events, for example, would usually never trigger). See EventWML and WML_Abilities
  • [variation]: Defines a variation of a unit. Variations are invoked with an [effect] tag. They are currently used for graphical variations (giving character sprites new weapons) but theoretically you could do anything with it.
    • variation_name: The name of the variation.
    • inherit: if yes, inherits all the properties of the base unit. Defaults to no.
All other keys in [variation] are the same as for [unit_type] itself.
  • [male], [female]: They can contain all [unit_type] tags, to specify a variation of different gender for a unit.
    • inherit: if yes, inherits all the properties of the base unit. Defaults to yes.
