Happiness

Happiness is determined by the sum of the addition by Happiness Sources, minus Happiness Consumption.

Happiness must be managed carefully, especially on harder difficulties as Unhappiness will cause your population growth to stop and Unhappy units have a -20% production debuff.

The Eikthyrnir Clan benefits particularly from because of the knowledge :

Young and Proud

Increase the Attack of your warband by 3% for every positive Happiness you have (25% max).

Effects on the Settlement

Happiness is the factor that determines how fast your Clans population will grow. While Happiness is 0 or above new Villagers will spawn at your Town Hall. The more positive Happiness you have, the faster new Villagers will join your clan.

(Thanks to Steam user "Bow to Gbowee" for the formula.)
