Fourth Tiers
The following tiers only exist in theory. The Ordo Dracul has not uncovered concrete proof that they exist (or at least, such proof hasn’t been disseminated to the covenant at large). In some cases, a Kindred might be able to demonstrate her mastery of a new tier without being able to teach others how to manifest it. If the effect of a tier cannot be duplicated in other Kindred to the satisfaction of local Dragon authorities, it might not yet be recognized as a Coil at all.
Which of these powers, if any, are obtainable in your chronicles is, of course, up to the Storyteller.
Apocryphal Coils
As Kindred of the Ordo Dracul have experimented with the philosophies of the Coils, they have found other, related ways to change the nature or the effects of their curse. Some of these changes, despite being related to the Coils, do not demonstrate the larger philosophies of the Coils of the Dragon, however. Whereas the Coils of the Dragon are meant to overcome the curse laid upon Dracula and all Kindred, these apocryphal pseudo-Coils either subvert the power that was bestowed with the curse, or warp the nature of the curse without truly overcoming it. These philosophies are not officially welcome within the covenant. Knowledge of these powers is forbidden. Dragons found to have studied them should expect to be severely punished. Knowledge of these powers is one of the few ways for a Dragon to be driven out of the covenant — though most such Kindred are rendered into ash within a few nights thereafter.
These apocryphal philosophies are learned, however, exactly like new dots of the Coils of the Dragon, as described on p. 149 of Vampire: The Requiem. The “rungs” or tiers of these philosophies are included in the total number of dots a character has learned in the Coils of the Dragon. Therefore, learning these forbidden ways increases the cost of learning new tiers of the Coils of the Dragon in the future. Though these are not philosophically compatible with the Coils, the effort and will necessary to learn them is the same.
Note: These powers may not even exist in all chronicles. The Storyteller is encouraged to carefully consider the ramifications of any apocryphal Coil on her chronicle before choosing to include them.
