Harmony

Harmony is a racial mechanic for Grand Cathay that affects both campaign and battle.

In Campaign

Each Province has its own Harmony level, which provides various campaign effects based on the current balance (or imbalance) of Harmony.

A province's Harmony balance is measured by the amount of Yin and Yangbuildings that are built in that particular province.

If there are more buildings of either type, the lowest amount is subtracted from the highest, which determines the overall level in the province, e.g. 3 Yin buildings and 2 Yang buildings results in a Harmony level of 1 Yin.

Imbalance results in various degrees of both positive and negative effects. However, when Yin and Yang are equal only positive effects apply.

The specific effects for each level of Harmony are shown in the table below, and can also be found in-game in the tooltip of the lotus indicator at the top of the Province Info panel.

In Campaign (pre patch 4.0)

Harmony affects

• Control
• Building Income
• Diplomatic relations with other Grand Cathay factions
• Growth
• Untainted Corruption

Being In Harmony brings the maximum boons to the above. Otherwise, they will get worse or even become debuffs the further Harmony becomes out of balance. --- Yin and Yang are inherent traits of the following:

• Characters (Lords and Heroes)
• Buildings
• Technologies
• Events

In Battle

Units are split into either Yin (ranged) or Yang (melee). Opposite units need to be within a certain radius of one another to be considered In Harmony and maintain their combat buffs. In this regard, unit positioning and army composition is more important for Grand Cathay than other factions, as these buffs are significant enough to determine the outcome of battles.

In addition, some units classified as Yin or Yang also have some abilities:

• Battle Harmony: Yin
• Battle Harmony: Yang
