Ilium

Overview

The rare material Ilium can be used to give a ritual enchantment or curse a permanent duration. Some other rituals can also incorporate ilium to get additional effects such as Distill the Serpent's Stone; such cases are specifically mentioned in the ritual description.

Using Ilium in rituals

To make the effect of a ritual permanent requires a number of rings of ilium equal to three times it's magnitude, with a minimum of ten rings.

Effects that lower the magnitude of an effect do not change the amount of ilium it requires to make it permanent. The ilium must be consumed when the ritual is performed; an existing enchantment cannot later be made permanent with ilium.

Only enchantments and curses with a duration of Season or Year can be made permanent in this way.

Removing a permanent effect

Making an enchantment or curse permanent only affects the natural duration of the effect, it does not impede other methods of removal or other restrictions on their duration.

A ritual requires an additional condition to prevent it ending prematurely (for example, a mark on the face or that the target be incapacitated) then a permanent effect still ends if that condition is not being met.

For example, the various rituals that grant additional production to farms such as Blessing of New Spring are rarely performed using ilium because such rituals always end at the start of winter.

There is one exception however; an enchantment that is made permanent with ilium is not supplanted if the target is subject to another enchantment unless that enchantment also uses ilium. The permanent enchantment persists and the new enchantment fails. A permanent enchantment can be removed with ritual magic, although there is no formulaic ritual in Imperial Lore at the moment that does so. The magnitude of the ritual must equal or exceed the number of rings of ilium used to create the permanent enchantment

Roleplaying effects

The roleplaying effects created by many rituals are also made permanent when the ritual is made permanent. As such, they cannot be removed with the ceremony of exorcism.
