Circle of the Stone

Circles of the Stone are mostly comprised of dwarves and other subterranean races that dwell in inaccessible mountainous regions or sunless depth below the surface. While helping dwarven enclaves to build and expand, members of the Circles of the Stone try to prevent reckless mining and irresponsible depletion of precious ores and minerals, seeing a great peril in leaving layers of “dead stone” in your wake. Druids of the Circle of the Stone are often known as "stone speakers" and seen across the realms as wise and unbiased advisors for anyone who is sensible enough to listen to their words, but it is also not unknown to see them charge ferociously into a cauldron of battle or man the front lines.

Features:

You gain proficiency with light hammer, and can ignore metal restriction on weapon (but not armor).
