By Alejandro Melchor, for the Nahual tribe.
The Nahual can transfer his soul to his nahual, an animal linked to her (chosen when creating the carachter). The Nahual must defeat the Gauntlet with a Gnosis roll. When in her nahual, the Bete can use her Gifts with a +3 difficulty and cannot travel to the Umbra; she assumes the animals Physical Attributes as well as Appearance and Manipulation, but retains Charisma and the Mental Attributes, as well as all Abilities performable in her current body. Damage done to the nahual animal is damage done to the Nahual, even when she doesn't inhabits it. 5 successes allow for an actual shapechange; the Nahual thus has no penalties whatsoever.
