Shamanism is nature magic used by Uriash elders, drawing on fog and lightning. Coen can learn it in the Pilgrimage of Power questline by finding glyphs carved into stone monuments.
Follow Pilgrimage of Power and look for glyphs on stone monuments around the valley. Each one teaches Coen a new piece of Uriash magic.
Bakr-Erga, the Uriash elder, can call lightning and change into animal forms. Magic is not common among the Uriash, so she stands out.

Blood Surge is a night-only Vampirism ability that makes a target burst from the inside through their own blood. You unlock it by drinking Xanthe's blood, so it is tied to her questline.
Compel Soul
Compel Soul is the first Witchcraft hex Coen learns, from Anca, after Laslea is sacked. It makes the recently dead replay the moments before they died, which is how you crack many investigations.
Crimson Rush
Crimson Rush is a Vampirism power that makes your active abilities hit harder the healthier you are. It is open from the start, so you only need Corruption and skill points to learn it.
Mesmerise
Mesmerise is a Vampirism power that lets you take control of an enemy's mind. You unlock it with Lacra's blood during The Night of Horrors, so it comes from story progress.
