War God numbers/functions are series of functions coined by FDLevi. Although it is not clarified in the source, the functions are intended to be defined on the set of positive integers.

The system originally included three families of functions, and later the creator added the fourth family. As the functions are defined as the iteration of multivariable functions whose diagonalisations are bounded by constant iterations of $$f_{\omega^2}$$ in Wainer hierarchy, they are bounded by $$f_{\omega^2+1}$$. Since the system directly uses BEAF up to $$f_{\omega^2}$$ level, the contribution of the original effort by the creator to ordinals in Wainer hierarchy is smaller than $$1$$.

## Classic ones

The first family is called the functions in order to distinguish it from the other families, and is based on the Arrow notation.

### Eris(x)

The first one in the functions is Eris.

Eris(x) = x↑x↑xxx

### Phobos(x)

The second one in the functions is Phobos. This grows faster than Eris.

Phobos(x) = Eris(x↑Eris(x)↑Eris(x)x)

### Ares(x)

The third one in the functions is Ares. This grows even faster than Phobos does.

Ares(x) = Phobos(x↑Phobos(x)↑Phobos(x)↑Phobos(x)xx)

### Kratos(x)

The fourth one in the functions is Kratos. This function grows faster than Ares.

Kratos(x) = Ares(x↑Ares(x)↑Ares(x)↑Ares(x)↑Ares(x)↑Ares(x)xxxx)

### Hades(x)

The fifth one in the functions is Hades. This function grows faster than Kratos.

Hades(x) = Kratos(x↑Kratos(x)↑Kratos(x)↑Kratos(x)↑Kratos(x)↑Kratos(x)↑Kratos(x)↑Kratos(x)xxxxxx)
