• There are two types of resources in Shadow Era:
  1. Casting Cost Resources (abbreviated as CC); which are built by sacrificing cards.
  2. Shadow Energy Resources (abbreviated as SE) which are automatically built each turn (on one condition).

These are two key-concepts in the Shadow Era game and need to be explained on different articles.
They are used for and by players to play cards and activate abilities.
Turn Number, Casting Cost and Shadow Energy are the three prerequisite resources for the players to play cards.
