É o máximo que uma dificuldade de tarefa pode ser facilitada 4 sem aplicar Esforço?

As regras sobre resolução de tarefas estão descritas abaixo:

A character’s level of skill is either trained (reasonably skilled) or specialized (very skilled). If you are trained in a skill relating to a task, you ease the difficulty of that task by one step. If you are specialized, you ease the difficulty by two steps. A skill can never ease a task’s difficulty by more than two steps. Anything else that reduces difficulty (help from an ally, a particular piece of equipment, or some other advantage) is referred to as an asset. Assets can never ease a task’s difficulty by more than two steps. You can also ease the difficulty of a given task by applying Effort. (Effort is described in more detail in Chapter 8: Rules of the Game.) To sum up, three things can ease a task’s difficulty: skills, assets, and Effort.
