A shaman of the land tunes himself or herself to the surrounding land, gaining powers thematically in line with his or her environment. A sufficiently powerful Shaman can also shapeshift into his or her "spirit animal", a mundane animal that reflects the inner character of the Shaman somehow. Shamans grow more powerful the more lands the they visit and tune themselves to, making them able to gain more powers from the lands they visit as well as bolstering their spirit animal form. A shaman who has grown sufficiently powerful is singularly terrifying, able to improvise and adapt the power they get from a land to suit their circumstances.
Musts:
A shaman of the land must have a High Concept reflecting the fact that they're a shaman, such as DEFIANT SHAMAN OF THE LAND or SHAMAN AND PSYCHO. They also must take:
Mimic Land (as Mimic Abilities, but the Shaman must take abilities based off of the themes of the environment. This can include anything that fits in with the surroundings. Players are expected to get creative.) [-4]
Moderate Limitation (shamans can only hold onto the abilities they get from a land as long as they are in said land.) [+1]
The Land Sustains (reskinned Wizard's Constitution) [+0]
Additional Options:
A shaman may increase the number of his or her Mimic Abilities up to as many times as he or she can afford (adjusting Limitation accordingly). If a shaman has done this at least once, he or she becomes eligible to be able to shapeshift into his or her spirit animal and may therefore take:
Echoes of the Beast (Varies) [-1]
Beast Change [-1]
In addition, the shaman may take permanent physical powers and Creature Features, but they must be attached to Human Form [+1]. Given that a shaman derives his or her power from growth, any toughness powers carry an up to a +2 Catch of Necromancy and Outsider Magic.
Important Skills:
Depends. Many Shamans can shapeshift, so they can switch skills around. But nearly all of them have high Alertness and Lore.
Criticism welcome. I want to refine this enough that I can get it onto the Templates Section of the Wiki.
