Okay, so Hex has Binding, Curses, and Invocation. Invocation is kinda loosely defined as yet, but it's kinda has to do with bring the power of things into yourself, or into someone else.
Sacramancy has Blessing, Cleansing, and Rebuking.
Animism has Communion, Restoration, and Spirit Walking/Astral Projection.
Putting them all together like this makes it pretty clear that Sacramancy is not needed, and it's presence kinda implies that Animism isn't proper sacred magic, which isn't right. So, even if it means eventually changing the name of Hex, I think that Rebuking can live in Binding, and Blessing and Cleansing are redundant with Restoration.
So, new question:
What are some good names for Hex, and the "go into the spirit world or project your spirit out into the world without your body" skill. Astral Projection is too long to fit in the space skill names fit into on the character sheet, and also feels very New Age woo, to me, no matter how much I tell myself it isn't.
Spirit Walker is...well, I don't know that it is actually appropriation, but it doesn't come across well.
I'd perhaps use something like Loquitur Manes/Lares/Spirites
I thought about Vox, and I think that some common titles for Animists will be Vox, Loquitur, Venerator, Keeper, and some others suggested in this thread.
Trance is used to travel to and navigate the spirit world
Trance would probably work, especially with the goal of skills giving generous freedom for interpretation by the player.
