I have been pondering Hermetic Architecture and how it works. I'd be very interested in peoples opinions on my worked example below and particularly on my queries and conclusions. If Neil Taylor and CJ (The Mysteries Revised authors) are about and willing to comment, I'd be super happy too
A magus, lets call him Jim, wants to enchant his home to up the magic aura. He already has a really good aura with a strength of 7 but wants to up it to a fearsome 9.
Question 1 - Can the increase aura effects from Hermetic architecture be stacked, i.e. could he put 2 effects into his enchantment, one to raise it to 8 and another to raise it to 9?
Jim calculates that his home, a castle occupies and area consistent with a boundary effect and is made of hard stone (i.e. size 8, *4 multiplier) and so would require 32 pawns of vis of enchantment spaces. He therefore creates 8 wands made of gold (size 2 * material 10), each tipped with a semi-precious gem (size 1 * material 12). Each of these wands has 32 enchantment spaces and he requires 8 of them due to the boundary size of his castle.
Jim opens the wands for enchantment using 256 pawns of vim vis. He considers that if he does this again, he will pay for the services of a verditius or someone with philosophic alchemy or celestial magic.
Jim then enchants the "Increase Aura effect" into the wands
Increase Aura 1
Increase the aura from 7 to 8
(Base 70, +1 touch, +4 boundary, +14 levels for always on)
Costs 11 pawns of vis to enchant
Increase Aura 2
Increase the aura from 8 to 9
(Base 75, +1 touch, +4 boundary, +14 levels for always on)
Costs 12 pawns of vis to enchant
Question 2 - Does Jim need to enchant this effect separately into each of the wands, i.e. making 16 enchantments in total? Or does Jim make the enchantment once to cover all the wands. This either costs him 184 pawns of vis or 23 pawns of vis.
With the items enchanted, Jim places them in the correct locations with an int + Artes Liberales roll of 14 (base 6+ the size of 8).
He then casts the ritual Bind the Mystical Structure to link them together. This needs to be level 140 (highest enchantment effect level of 114+5, +2 magnitudes to bump it to boundary). This costs 28 pawns of vis and takes 7 hours.
Question 3 - The description says this is a special ritual and more like the rites of the mystery, using the spell rulles for vis consumption and calculations. Does Jim need to invent this ritual in the lab or can he just go ahead and cast it?
With all the components now linked, Jim settles into enjoy his aura of 9.
Question 4 - In total, has this cost Jim 468 pawns of vis, or 307?
Now, as it stands, either way, I can't see this being even slightly worth using. But, if Jim were an appropriately powerful Verditius, with Philosophic alchemy or celestial magic (or even better, both), or with access to such a person, the costs could be dramatically reduced. Even a normal verditius, fresh from his gauntlet, with a craft score of 5 could reduce the costs by 40 pawns of vis.
Question 5 - Has anyone actually used Hermetic architecture in game, and what did they do with it?
