Most actions you take in the game have an action cost. This determines how long it takes you to perform the action.
The standard action cost representing a "one-turn" action is 1000. All action costs are randomly varied by up to ±10% in order to make the initiative order of the game less deterministic.
| Mechanism | Amount | Scope |
|---|---|---|
 Two-headed |
-20% to -56% | Mental actions |
Modding note: at an internal technical level, this concept is referred to as "energy". "Action cost" is used in public facing materials to avoid confusion with things one thinks of first when thinking "energy".
