Build

Worm-King: Raises a dead thrall or gives an arbitrarily high amount of health to an undead under your control.
Incapacitate Undead: Turn any level undead for 10 seconds and also slows them by 99%.
Sacrifice (lesser power): Absorbs 10 health per second from an undead under your control until it dies.

Attunement system:
Favour system: To get a patron, you need a favour token for that patron. The patrons are:
The Lost Hist
The Fallen Star
Mannimarco
The Ideal Masters
The Nullifier
The Nameless patron
The Phantasmagorical.
Favour tokens for each of these can be acquired from one of the various new crafting stations around Fellglow Keep, more detail in the Fellglow Keep overhaul section.

Felglow Keep Overhaul
New crafting stations, notes, etc. have been added to the exterior and first 2 interior cells. These are all self-explanatory ingame. The ones marked with * are used to make patron favours as well for the attunement magic system. Exterior: meteoric glass boulder, ayleid well, lens array*, compost heap, hist sapling*. Interior 1: vampire blood, corrupted shrine*, soul cairn portal*. Interior 2: magic anomaly*, extraction set*, hollow log, fireplace*, aedric essence extractor and ritual bowl.
The new craftable consumables (eg. aedric essence infusions) do not have permanent effects.

Everything required for each token is available around the keep if you look hard enough. These favour tokens will not be visible in the crafting menus until you have read the ritual notes.

The ritual: To perform the ritual you need to read the spell book on the table in the room where the stone of barenziah is in fellglow keep. This will give you a spell to change your mind to erase the spells from your spellbook and another spell to perform the ritual. The ritual will fail unless you have a focus ring attuned to a patron equipped when you perform it, though this ring is not required after that point.
The ring is crafted with the blue-fire in the room.
Casting the ritual with an attuned focus ring will remove both the ritual spells and give you your three pact spells as well as the debuff. The debuff gives a flat -100% magicka regeneration.
