Runesmiths are most often dwarf that have learn the ancient crafts of working metal and magic into Runes of power. But other races have be known to taught the secrets of runemaking. 

Mastery of the runes has made the Dwarfs the pre-eminent creators of magical items and many famous magical weapons were crafted by Runesmiths. It is no wonder then that the Runesmiths do not share the power of the runes, and only guild members are allowed to practice the art. Rune magic takes a fundamentally different approach than the art of wizardry. They believe wizardry is inherently unsafe, they craft runes to bind the magic inside it and hold it. When so confined, the magic can be used safely. Runesmiths treat magic like any other Dwarf craft. Mastery takes patience, hard work, and dedication.

Runesmiths constantly search for lost runes. Any Dwarf-made artifact of antiquity is examined, not only to marvel at its expert craftwork, but also to seek for hidden signs. In some cases, runes fade over thousands of years as their magic gradually leaks away, although this does not happen with master-forged items.

During battle, they will be in to front, dealing damage to foes and calling upon they runes of power to aid their allies.
