Souls

Basics
Souls are the basic currency used in Demonic Defense, and all defenders and demons make very good use of them.

Defenders
Defenders can acquire souls after the Demon spawns in the game. This is done by visiting the active Ethereal Rift on the map with your main builder/defender. An Ethereal

 Rift spawns every 3-6 minutes at one of random eight locations on the entire map. You can always check the location of an active Ethereal Rift by typing "-loc" (Without the quotations). You can also toggle on/off the "Rift Duration" timer by typing the command "-displaydur" (Without the quotations). While standing in the Black Tile terrain

surrounding the Ethereal Rift, you will gain 1 soul every 2.25 seconds.

Demons and Imps
Demons and Imps can acquire souls by destroying enemy structures, or by killing an enemy main builder. Some harvesters give souls on death. Below is a list of the amount of souls rewarded for destroying each type of structure. Please note that every type of structure listed is generic for every builder, unless that builder cannot build those structures.
 * Towers - 3 Souls (Kodo Tower - 12 Souls)
 * Food Shelters - 4 Souls
 * Research Centers - 6 Souls
 * Advanced Research Centers - 10 Souls
 * Resource Points - 2 Souls
 * Walls - 2 Souls (All walls are classified here, unless they have the "Enhanced Prefix")
 * Enhanced Walls - 3 Souls
 * Demonic Towers - 10 Souls
 * Demon Hunters - Varies from 15-30 Souls

Trivia
Originally Souls were intended to be gained by standing in the portal located in the center of the map. This was removed for a multitude of reasons, primarilly because it led to Demonic Defense being very similar to the highly acclaimed Warcraft III game "Island Defense".

Originally souls were gained every .75 seconds. This was quickly removed, as this led to builders having the ability to get their max tier upgrades in a matter of minutes.
