Classes (SoW1)
In Symphony of War: The Nephilim Saga, the class system determines for units many properties they have when they are deployed on the field for combat. This involves statistics, such as armor and weapon score, along having a large influence on the development of maximum hp, strength, magic and skill. This is also influenced by level (only positive) and the affinity the unit has. Some traits are also determined by the class itself and for each unit, there are two trait slots which can be assigned, by using trait books. The class of each unit has a role on the type of squad it becomes.
The class tier determines how developed the class is, with the lowest tier generally having the least developed abilities and tier 4 generally having the most developed abilities. Development of a unit is determined by experience points and class points. The first increases the unit's level and improves a few statistics every time a new level is gained. Class points determine when the unit is able to change class - or alternatively at the highest available class, when the unit is eligible for using a Proof of Merit on.
