The Shoanti shaman is a very simple archetype that either clerics or druids can take (with GM permission, you can certainly adjust the archetype a bit so that other classes with access to domains can be a Shoanti shaman, but keep in mind that the Shoanti have a very specific flavor, and something like a Shoanti inquisitor is kind of weird...)—doing so allows the character to gain access to his clan's totem domain. A Shoanti shaman has the following class feature.
At 1st level (for clerics) or upon gaining a domain as part of Nature Bond at 1st level (for druids—a druid who instead opts to take an animal companion cannot use the Shoanti shaman archetype), pick one of your Shoanti quah's totems. You can use an image of this totem you carry or wield as your divine focus in addition to using the normal divine focus you might utilize (such as a holy symbol). In addition, you add that totem's domain choices to the list of domains you may choose from when picking a domain. If you are a cleric, you must still choose one of your domains from those normally granted by your deity. If you are a druid, your totem domain options replace the standard domain options granted by nature bond.
