"Mythic Form." A devotion?

[Xizzicks]

I'd like to implement something in my game where Kindred can take on a "mythic form." It would be a devotion that grants "features" (similar to protean.) based on the disciplines used in the devotion formula. How should I implement this? Should it be a coil or something instead?

[Stupid Loserman]

What's the flavor you're looking for here, what is it about the Kindred that this mythic form draws upon? Is it a relatively common capability, as far as powerful vampires go, or is it emblematic of a rare few memorable elders? Is it expressive of the basic nature of the Blood, or a more exotic twisting of the Curse?

Generally speaking, it probably shouldn't be a Coil unless it's meant as an especially exotic, unusual twist on the Curse. A common expression of powerful vampires might go as low as a base requirement of Protean ●● or even just a raw Blood Potency requirement, while a rare and memorable Devotion probably would start with Protean ●●● and some amount of Blood Potency, adding in some requirements of other Disciplines (not necessarily specific ones; perhaps something more like [Physical Discipline] ●●● or [Mental Discipline] ●●), with results based, as you say, on what Disciplines the vampire is able to add into the mix.

I'm being inspired by the "Vampire Lord" form in Skyrim's Dawnguard DLC and the Legacy of Kain series's vampire "evolutions." But I definitely want this to be an uncommon ability.

I'd say just Protean 5 Devotion as the base power is already a completely supernatural transformation into an entirely different form.

Mythic Form was a Protean 6 or 7 thing in VTM iirc. If I were to even attempt to pitch this to my group they'd probably want Protean 5 Vigor 5 Resilience 5 (or at least 3 Vigor/Resilience)

[Tessie]

Remember that Force of Nature is Protean 4, Resilience 4 and Vigor 2. Mythic Form, depending on how powerful you want it to be, probably shouldn't have much higher requirements. And also remember that requirements should depend on what makes sense, and if the Devotion turns out to be more powerful you should increase the XP cost instead of the requirements.

[Rathamus]

I don't see the reasoning for other phys reqs beyond just upping XP cost. If XP cost is the thing, then I'd say just require a dot or two of any other phys Discipline.
FoN's flavor text makes some sense about needing Vigor and Resil to give wacky forms structural integrity and locomotion where they should otherwise collapse into a blob. FoN is also WAY more powerful than any single form simply because it can take that form and next turn be something completely different.

Next turn? You can change reflexively which my group and I have interpreted as being able to do it several times each turn. It has happened a few times that I've used Swarm Form to break a grapple before the grapple rolls and then turning back again just so I can make a different type of attack (or attack a different target) since we've houseruled that grapple actions (such as initiating or escaping grapples) uses up your instant action. (The exception is that getting an Exceptional Success when initiating your grapple allows you to take one grapple action the same turn.)

What do you mean house-ruled, pretty sure it's an instant action regardless. That's how my group interpreted it anyway. If you have proof otherwise let me know / give me a citation.

If I was pitching this I'd include Geographic and relic limitation to the Devotion. Such limitations might be the Devotion can only be learned directly at and used within a certain radius of an active worship sites of mystery cults dedicated to the deity. I'd note there is a real life temple of Set in Portland Oregon and San Francisco California, and having vampires wanting to rekindle ancient Devotions is a neat Chronicles of Darkness explanations.

If a covenant specific discipline was part of these devotions it should not be dragon scales nor thesban sorcery, but Cruac. The worship of pegan deities and rite are part of the circle of the crone's themes, and becoming avatars of such beings is appropriate mechanically and themeatically.

Along the relic line, it adds reasons for the use of macguffins, all being ancient artifacts with no power themselves but allow the character to develop and use powers, like the spear of Lugh (a Majesty 5, Cruac 5, Protean 5, Resilience 5, Vigor 5 devotion would fit the description of that object's power and be very spear of destiny plot worthy)
