Thank you very much!
Now, I get the system and and you suggestion look pretty fair.
About essence - here is description:

ESSENCE
Essence is the ephemeral energy of the Hisil. It’s the food and fuel of spirits. It’s the manna that keeps the Shadow
pulsing. It’s a currency, a resource that motivates an entire food chain to predate. To the Uratha, it fuels Gifts, it heals, it speeds shapeshifting, and it activates fetishes.
It flows through every spirit, and comes into existence usually at loci, but sometimes in other, stranger places.
GAINING ESSENCE
Uratha gain Essence through a few key places:
• They can absorb Essence through the wellspring of a locus (analog of Nevernever doors). In the Hisil, this means physically touching the locus at its heart. In the physical realms, this means devouring the strange bits of meat and vegetation that appear near the locus.
• The Sacred Hunt rite, the Siskur-Dah, allows a pack to hunt and devour spirits in the Hisil. When eaten, the spirit’s Essence flows through the Uratha.
• They can eat the flesh of wolves and humans. For every point of damage caused by an Uratha’s bite, they can choose to
ingest the flesh and gain a point of Essence. This is a stark violation of the Oath of the Moon, and always a Harmony breaking point toward the spirit. When devouring flesh for Essence, the Uratha causes aggravated wounds.
• Fetishes store Essence. By destroying a fetish, the Uratha can take the Essence within.
• The first time an Uratha sees her auspice moon at night, she gains a point of Essence.
USING ESSENCE
Uratha use Essence for numerous purposes. How much Essence a werewolf can spend in a turn is dictated by her Primal
Urge score, as detailed on p. 93. If a Gift or other effect would require she spend more Essence than she may in a turn,
she can spend the required Essence over a number of turns, with the ability activating once she has spent the total needed.
• Uratha normally regenerate bashing damage every turn. By spending a point of Essence, the werewolf regenerates
lethal damage instead. See p. 93 for details.
• Uratha can reach across the Gauntlet with time. Spending Essence can speed the process. See p. 101 for details.
• Depending on Harmony, some werewolves need to spend Essence to change shape. See p. 104 for details.
• Certain Gifts require Essence to activate.
• Fetishes often require Essence for use.

Anyway, considering thewide range of the forms, the easiest way is to give them "improved" Beast change [–2], and Human Form can be considered as [+2], because of some complications.
So, the final Power-set of Mahmoud is:

Powers
Echoes of the Beast [–1]
Beast Change [–2]
Human Form [+2] affect (one way, or another):
Claws [–1]
Inhuman Strength [–2]
Inhuman Speed [–2]
Incite Emotion [–1] - Lunacy (delirium)
Inhuman Toughness [–2]
Mythic Recovery [–6]
The Catch [+2] - silver
Feeding Dependency (Essence) [+1] affect:
Supernatural Recovery [–4]
The Catch [+2] - silver
Ritual [–2]
Channeling [–2] (Gifts is not normal spell-craft and mostly similar to Minor Talents/Stunts, but they are diverse, can be improved, and there's many of them)

So, 19 FP.

What do you think, how tough this guy could be in Dresden-verse? I ask, cuz I'm not sure that the same-cast abilities of the RPG are equal, especially in combination with each other.

Thank's.
But why the DF isn't good for this? I mean, as DF as WoD are urban-fantasy adventurous RPG (maybe WoD is quite darker). I used physical meaning of traits and influence of stats to probability of success.

With a great help (especially Haru), I finished the conversion of one World of Darkness ready-made character in DF.
During this I:
-finally get how DF RPG actually work
-understood the base template of WoD-werewolves in DF, and now can (I think) write all the template for 2.0
-I radically revised opinion about power-level of Dresdenverse (I really thought, that WoD monsters will be way stronger, but... no, they are actually equal)

The character I conversed were quite strong and cool, but here he is just strong-but-not-overpowered-dude. Anyway, ladies and gentlemen, please welcome

Mahmoud "WALKS-FROM-THE-LIGHT" Abdul-Rahim

Aspect
High Concept: Monster, who hunting monsters
Trouble: Lone Wolf
Other Aspects: When you look long into an abyss...
                      Bad-ass motherfucker
                      Cold eyes
                      When you’ve got a big-ass hammer, why look for anything but a nail?
                      Tired of being alone
                      It wasn't THAT bad (in response to gossip about his achievement)

Background:

As a lost cub in his mid-20s, Mahmoud was taken in by a mixed Blood Talon and Iron Master pack that was alerted to his Change by local spirits. Over the years, the sensitive and good-natured young man became a ferocious killer and savage protector of his family and territory. Clever (or malicious) spirits would target Mahmoud as the most dangerous of the local pack, and attempt to harm his family as a way of getting to the werewolf. The foulest of these attacks involved the rape of his sister. Mahmoud tore the culprit torn limb from limb, shredding both its mortal host and the spirit responsible.
On that night, Mahmoud went to war against the darkest pits of Shadow.
Now in his early 40s, Mahmoud wanders the world alone, seeking out suitable Uratha for induction into the Lodge of Night. He is not averse to joining a pack — in fact, he deeply desires the unity of such a bond — but, in his eyes, his lone questing is a necessary sacrifice. The Lodge of Night must be spread and new members brought in; and none know the truths of the lodge as well as Mahmoud. He never took the name “Walks-From-the- Light,” and instead smiles with grim amusement every
time he hears it spoken. It was awarded to him (perhaps forced upon him is a better term) in light of his journeys and deeds. Every lodge member has heard of him, and his exploits may well have been exaggerated.
Walks-From-the-Light looks old for his age. His dark skin is weathered, and his face shows grayish stubble that rarely sees a razor. He is handsome in a rugged way, appealing to anyone with an eye for the older man. When his anger is suppressed, he is good-natured with a dark and sarcastic sense of humor. When angered or merely trying to threaten someone, his expression is little short of murderous and utterly barbaric. No matter his state of mind, his dark eyes are impenetrable — deep, dark and unreadable.

Stress
Mental oooo Physical oooo(oo) Social oooo, Armor: 1

Total Refresh Cost: -17

Oh-kay.
An example - my character tears off vampire's feet (for example, it's a consequence of losing all stress-dots). Can it mean, could that vampire considering as take out?
Other question: if character is NPC can I ignore the skill progression (1 Skill 5, 2 Skills 4 etc)?

If I may, I will ask here.
Living Dead [–1] give to character the

Death is a Nuisance. Unless wholly destroyed or killed by special means, you’re already
dead, and that doesn’t seem to have fazed you much. No “death” result is ever permanent unless special means are used (usually as determined by your creature type).

So, why will be if someone completely marks off all the stress boxes?
 

OK, thanks. 
I just want to make conversion for nWoD-splats' characters (yep, Dresdenverse vs World of Darkness is my idee fixe). The problem is that it's hard too compare because of settings and systems are different.

Hm-m... Do you know the nWoD (2nd edition) system?
