Skills may have a different meaning in roguelike games, some of the more common approaches are the following:
- As a value that defines how good certain character is when he tries to perform certain kind of action.
- As an action that certain character is able to perform, optionally with an embedded proficience value on this same action.
Skills may be active or passive
Active Skills: The character must explicitly declare he is going to perform the skill, optionally defining different arguments for its execution.
Passive Skills: These skills are used expontaneously or implicitly, without direct input from the character.
