This hammer is shaped like a miniature warhammer which has been scaled down and adjusted slightly to be able to be wielded as a one handed weapon. The sides of the hammer depict holy symbols related to a god with an image of radiating light on the top. The handle is equally as ornate though with less specific patterns and a flatter design that can be gripped for long periods without difficulty.

This hammer functions as a holy symbol of a specific god or pantheon in addition to serving as a casting focus, thus allowing it to simultaneously fill the roll of a divine focus.

A hammer of holy light can be wielded and enchanted as though it were a masterwork heavy mace.
