I will preface by saying that Tand is not precisely a shaman, but a geomancer. It is a more primitive practice of shamanism and has more to do with appeasing the elemental spirits with offerings, dances, songs, and runes, rather than the shaman’s way of ‘‘verbal’’ communication.
Tand has elemental preferences borne out of the traditions that his birth tribe clings to. His tribe, the Mudtail, has a deep connection to the earth itself, and the water. They have lived in Dustwallow for generations, which has led to their competency with the spirits of Water and Earth.
He is still untrained, and he has been cut off from his teachings, so he does not know how to efficiently gain the favor of Fire, Air nor Spirit.
He does not keep totems on him, no. However! Tand follows the teachings of his birth tribe, and they have their own way of dealing with elemental powers. Whilst Tand and his tribesmen can control the elements around them in the conventional sense, they also make use of elemental crystals. We see in-game that there is solidified, or crystalline elemental essence stored within rocks and crystals. This is very much a thing he utilizes in his geomancy. He activates the latent powers within these crystals he has gathered and then uses said crystals for the appropriate task.
I am positive that Tand will never become strong enough to raise someone by his lonesome, with the exception if they are recently deceased, and their spirit still lingers around their corpse. For now, though, he is still untrained within the art itself, and a task such as this is too much.
Ever since Tand found his spiritual calling, at a very young age, he came to be bothered by night terrors and strange whispers. After many years of trying to put an end to it, even having tried to go down the road of the monk as well to seek serenity, it finally stopped after a visit to the spirit realm. It was a very taxing thing to do, and the Spirit Wolves had to tend to his lifeless comatose body for a while.
But after that spiritual journey, and having found out that the whispers and dreams were his ancestors trying to reach out to him, he hasn’t been in contact with them since. Partly because of the request to send them away was issued by his tribal leaders, in the Spirit Wolves.
