Rites of Prime Banishment

The Rites of Prime Banishment describe the ritual used to exile a god from the Material Plane.

History
The ritual has only been used once in the history of Exandria. During the events of the Calamity, the Prime Deities sought to re-imprison The Chained Oblivion. It took the full might of Pelor, with the blessing of Avandra and a near-fatal blow to Ioun, to defeat the mad god and complete the ritual.

Now that Vecna has achieved godhood and must be defeated, Ioun has granted the long-unused knowledge of this ritual to her champion, Scanlan Shorthalt, after he earned her blessing in.

The Prime Trammels
These long, silvery, javelin-sized spikes of platinum were originally forged by The Allhammer. They can be attached to a wounded god to aid in the Rites; the more wounded the god, the easier they are to attach.

Each Trammel is made from a fragment, or "bead", of divinity, and a large amount of pure platinum. To craft a single Trammel requires "the strength of a titan" and "the ingenuity of a madman."

In, Vox Machina traveled to The Allhammer's abandoned workshop to craft three Trammels of their own. They used one bead of divinity from Pelor, one from Ioun, and one from the Raven Queen. Grog, using his Titanstone Knuckles, provided the strength to work the hammer. Percy, aided by knowledge from Ioun, provided the ingenuity to engrave the surfaces of the Trammels.

Vox Machina succeeded in crafting their three beads of divinity into three Prime Trammels, though one may be more fragile than the other two due to difficulties during its construction.

The Tome of Isolation
This book, which has no title on the spine and is filled with blank pages, was retrieved by Scanlan to prove himself worthy as Ioun's champion, whereupon she gifted it to him for the fight against Vecna. The Tome has the following properties:

''As an action, you can expend a spell slot of any level higher than 3. The cover and the internal pages glow with the hidden text of the Rites of Prime Banishment. While legible, you can spend an action to invoke the Rites of Prime Banishment against a target. The target must make a wisdom saving throw. On a failure, the target is banished and sealed, and this book is immediately teleported to the Endless Atheneeum. On a success, the text becomes blurred until the end of your next turn. The DC of this ability is 10, plus 5 for each Prime Trammel fused to the target.''

With their three Trammels, Vox Machina will theoretically be able to attempt a Rite of Prime Banishment with a DC of 25 when they confront Vecna, though they will have to attach the Trammels first.
