Core Structure

The Core Structure is a gameplay element in Night of Oblivion. In the lore, it is the structure where the ashes of dead Heroes are stored.

Gameplay
It is an additional starting building alongside your Town Hall, but the Core Structure often provides forms of utility which can aid the player in different aspects such as boosting the economy, or improving an army. Each core needs to be Activated via a research before it can be used. The upgrade cost and duration vary for each race.

Core Structures also often contain some upgrades.

Each of the 4 races has a unique Core Structure:


 * Curator Force starts with a Celestial Core.
 * Defiled Swarm starts with an Aqua Core.
 * Exalted Order starts with a Mystic Core.
 * Fallen Conspiracy starts with a Shadow Core.

Each core has 3 abilities, with one ability for each of the aspects: economy, utility, and combat. All of them cost mana, so their opportunity cost is simply each other. All spells also have a cooldown of 20 seconds.

Celestial Core (Curator):

 * (Economy) Force of Nature: Summons 2 Treants.
 * (Utility) Sentinel: Summons an Owl Scout which provides vision for 120 seconds.
