75% 侵略扩张, 100% 威望和100%战争分数用于:
随时间推移的战争分数来自于战役获胜； 如果交战一方通过战役胜利获得了大于10%的战争分数，那么then the wargoal will start ticking in their favor.
Using this casus belli has the following effects:
75% aggressive expansion, 100% prestige and 100% warscore cost for:

The casus belli targets a specific province and ticking warscore is based on control of that province.
Steppe shock bonus
On provinces with flat terrain, hordes get a 25% increase in damage during the shock phase. Affected terrain includes Plains, Steppe, Farmlands, Grasslands, Drylands, Coastal desert and Desert. However, on provinces with no flat terrain (Hills, Mountains, Forests, Coastlines and Marshes), hordes get a 25% decrease in damage during shock phase. It does not matter if the horde nation is attacking or defending.
Under regular circumstances - Horde unity above 50 - when a horde nation ends up in a regency, the heir will be replaced by a new ruler with a strong claim from a random dynasty, and 25 horde unity will be lost.
A size 2 revolt of pretender rebels will spawn in a random owned province. The nation gets the choice of siding with the underage heir or a new ruler from a random dynasty. Siding with the underage heir will spawn revolts of size 1 of nationalist rebels in any province that is not cored and unrest will be increased by +10 in all provinces until the succession crisis is over. Siding with the new ruler will remove the current heir, appoint a new ruler and deduct 25 horde unity.
The crisis will end once the rebels win or all the pretender rebels are defeated. Defeating the rebels will increase stability by 1 and add 25 horde unity.
Hordes can raze uncored and owned provinces for monarch points at the cost of development in that province. Razing a province:
- provides all the remaining loot in the province and increases its devastation by 10%
- lowers the province's development by 1 in each category and an additional 1 for every 5 development in that category before razing (rounded up)
- provides 20 monarch points in each category for every point of development razed. This amount is reduced by 1 per level of military technology above level 8
- Provides 1 horde unity for every 2 points of development in the province before razing, regardless of the amount razed
- Decreases opinion of former owner by -25
Once razed, a province cannot be razed again for 20 years.
Development cannot be brought lower than 1, and provinces with 1 development in each category cannot be razed at all.
For example, razing Venezia (10/12/5), with total development 27, at military technology 5, would lower its development to 7/8/3, and provide 51, 68, and 34, plus 27 horde unity and any loot remaining.
- Note: If the tribes estate is disloyal, monarch power gained from razing is decreased by 50%.
Steppe hordes have access to a special form of subject type called tributaries. Tributaries retain full diplomatic independence and may start wars and have subjects of their own. The overlord receives a call to arms if the tributary is attacked (unless if by another tributary of the same overlord), but does not have to accept. Each year, the overlord may demand a tribute of money, manpower, or monarch points. If the tributary pays the tribute, trust increases slightly; if it refuses, trust falls significantly. Either party may renounce the tributary status at will, unless they have a truce
