The result is that many effects are possible from exactly the same base power.

Each such modifier makes the power more or less capable, and correspondingly more or less expensive to purchase with character points (the 'currency' used to buy powers see the section following). Most powers have a set of modifiers that alter their base performance to more finely-tune their representation of the effect desired. When creating a character, a player decides on what effect they wish to create, then constructs this effect by consulting the powers in the rulebook. Most powers are meant to be able to model a vast number of potential effects.

While the system does have more typical features of many RPGs, such as a skill system, most abilities in the Hero System rules are listed as generic 'powers'. Like Champions, it uses a tool-kit approach to creating effects.
