The harmony with oneself and one’s totem enables the adept to project a special aura onto others in his surroundings.
It can come across as intimidating, if in the Adept’s growl one seems to hear the deep rumble of a bear, or equally convincing when the Paladin’s tall, upright form almost seems to radiate from within.
In any case, the level of this ability counts as a bonus on Persuasion checks and on Nature checks when dealing with animals.
