The Cabirian Invocation is a ritual to break a spell or curse applied in a certain object. Rowena explained to Sam to use this ritual, which she described as "good all-purpose disenchantment" to break any spell applied to any object. Sam intended to use it to disable the warding on the Werther Box but the ritual was not completed correctly due to Suzie's interference.


The ritual is very simple. The user must prepare a mini altar consisting of a plate. An unknown purple flower must be put on the plate. A handful of yarrow powder is later poured into the plate and ignited. A Latin spell must be recited:

Purificare la magia

After reciting the spell, fire will rise from the plate.

It's unknown what would happen later if this ritual succeeded, as Suzie's interference made Sam fail the ritual. However, from its ashes, Rowena could craft a spell to illuminate the box which allowed them to know how to turn off the box.
