# Doctrines

## Important concepts:

* **Folder** - the category of doctrines, e.g. *land*, *air* or *naval*
* **Grand Doctrine** - mutually exclusive root of the doctrine folder, unlocked with XP
* **Track** - a slot for a subdoctrine and its rewards
* **Milestone** - an additional reward for completing a track
* **Subdoctrine** - can be slotted as the root of a specific track, unlocked with XP
* **Mastery** - the progress made within a track
* **Reward** - a reward for making gaining mastery within a track, belongs to a subdoctrine

## Doctrine Modifiers

### Doctrine Cost modifiers

* *[folder_name]*_doctrine_cost_factor
```
# Example:
land_doctrine_cost_factor = -0.15 # 15% cost reduction to grand doctrines and subdoctrines in the land folder
```
### Mastery Gain modifiers

Note: for these mastery gain modifiers, localization is automatically mapped, meaning you do not have to define unique localization keys for each generated modifier.

* *[grand_doctrine_name]*_mastery_gain_factor
```
# Example:
new_mobile_warfare_mastery_gain_factor = 0.15 # +15% mastery gain for all tracks which have Mobile Warfare as the grand doctrine
```
* *[subdoctrine_name]*_mastery_gain_factor
```
# Example:
guerilla_war_mastery_gain_factor = 0.15 # +15% mastery gain for all tracks which have Guerilla Warfare as the subdoctrine
```
* *[track_name]*_track_mastery_gain_factor
```
# Example:
infantry_track_mastery_gain_factor = 0.15 # +15% mastery gain for infantry tracks
```
