Assume they have a +0 Catch, and if the players come up with a creative bit of research that sounds plausible as a weakness later on, run with it.

OK, makes sense.

What the hell *is* Mouse? And mister...he's getting up in age for a regular cat.  IIRC Dresden'd had him for a while as of Storm Front which would be like 10 or 11 years ago...cats live like 15-20 years.

Mister was a kitten when Harry found him, 3 years before Storm Front. According to the timeline, Changes is 11-plus-a-little years after SF. So Mister is either 14 or 15 depending on when his birthday is.

We view each Harry novel as *roughly* 1 refresh point, though I'm not 100% certain that scans 1 for 1.

Wow... he's pretty high Refresh-cost even in the Storm Front stats we've seen. But then, he has improved his skills dramatically (especially in the more finesse-y stuff like Little Chicago), and things like Soulfire must be pretty expensive.

More on Evocations...

Evocation Check Modifiers
Supercharged emotional state  ... +2
Appropriate energy source within range (Improved Energy Use class feature*) ... +2
Make yourself fatigued (Skilled Evoker feat, or Wizard/Sorcerer, only) ... +4
Damage yourself (Wizard/Sorcerer only) ... +1/hit point dealt to yourself (maximum 1/2 your class level, round up)
Fatigued ... -2
Exhausted ... -4

Notes:
Supercharged emotional state: Applies when the evoker is fighting for something more important to them than life itself. This should be a rare bonus.
Appropriate energy source within range: This is things like Harry freezing water to power his fire. *See the class feature (whenever I get around to writing up the Wizard/Sorcerer class...)


Example: John Doe, a 4th level Wizard of the Council, is awakened by a suspicious sound and runs into the next room, where he sees a Renfield Black Court minion standing over his newborn son's crib. Fire is too dangerous to use in this situation, so he lights up with an Electricity evocation instead. To put as much power as possible into the decisive first shot, before the Renfield can harm the child, he makes himself fatigued (+4 bonus) and burns 2 hit points (+2 bonus). Since his son's life is at stake, he gains the +2 bonus for supercharged emotional states. Adding all these to his +2 Charisma modifier and his +2 bonus from his class levels, he rolls a 26 (base 14 + total bonus 12). The lightning bolt slams into the Renfield. Surprisingly, he makes his DC 13 (10, +2 Charisma bonus, +1 Wizard/Sorcerer class feature) Fortitude save for half damage despite his low save modifier; unfortunately for the vampiric minion, John Doe rolls 19 damage on his 3d8, and even half of that (9 damage) is enough to kill the 6-hit-point Renfield. John is severely winded by his exertion, but his son's life is saved. Of course, now he has to do something about the apparently-human lightning-struck corpse in his son's bedroom...


Electricity
Includes hurling bolts of lightning, supercharging metal objects with a deadly shock, etc.

DC    Range    Damage (Fortitude save halves)
5    10 feet  1d3 electricity damage
10    20 feet  1d6 electricity damage
15    40 feet  1d8 electricity damage
20    60 feet  2d8 electricity damage
25    90 feet  3d8 electricity damage
30    120 feet 4d8 electricity damage
+5   +40 feet +1d8 electricity damage

The lightning bolt's length is equal to its range (it extends from just in front of the evoker's hand, blasting rod, or other casting tool to the limit of its range). Unless shaped by a skilled Wizard/Sorcerer (using the Shape Evocation class feature), it is 1 inch wide and deep, so it will not harm scenery or innocent bystanders as fire will. (Of course, it is also less damaging than fire; there are always tradeoffs...)

The electricity evocation can also be used to make a single melee attack with a metal weapon as a full-round action. If it hits, it will deal normal damage plus electricity damage.

Wind
Includes shoving objects around, knocking your foes off their feet or into unconsciousness, etc.

DC    Range    Nonlethal Damage (Reflex save halves)
5    10 feet  1d3 nonlethal bludgeoning damage
10    20 feet  1d4 nonlethal bludgeoning damage
15    30 feet  1d6 nonlethal bludgeoning damage
20    50 feet  2d6 nonlethal bludgeoning damage
25    70 feet  3d6 nonlethal bludgeoning damage
30    100 feet 4d6 nonlethal bludgeoning damage
+5   +30 feet +1d6 nonlethal bludgeoning damage

The wind blast's length is equal to its range (it extends from just in front of the evoker's hand, blasting rod, or other casting tool to the limit of its range). Unless shaped by a skilled Wizard/Sorcerer (using the Shape Evocation class feature), it is 10 feet wide and deep, so it will throw objects around and otherwise wreck the area in a rather large chunk of the scenery. However, its effects on innocent bystanders, while they may be painful, are nonfatal.

A wind evocation is generally cast to knock down or unbalance your foes rather than to damage them. It deals the least damage of all evocations, but creatures who fail their Reflex saves are automatically knocked off balance (-1 penalty to attack rolls, saving throws, and evocation checks next round), and are knocked prone (if Large or larger) or knocked prone and shoved back 10 feet (if Medium or smaller) if they fail their saves by 5 points or more. Inanimate objects up to (50 pounds x the evocation check result) are shoved 10 feet automatically; objects less than 10 pounds are blown to the limit of the wind blast's range.

Re other systems for a DV game: I've been thinking about the possibility of using D20. A month or so ago I posted some stuff on the d20 thread. I really do think it could work quite simply...

If one wanted to use d20, d20 Modern would probably be the best base. Pure Mortals could use the base classes without any modification: Minor Talents and the weaker Changelings/Scions, as well as any other supernaturals who are 'one-trick ponies', would still use the base classes, but simply with a template applied (with their weak powers balanced by minor weaknesses: for example, Changelings weak enough to use this setup would have one minor ability, either a very weak magical one, a weak bonus feat, or simply a bonus to an ability score, and would be vulnerable to iron; they might also suffer a penalty to certain social skills as they have less free will.)

For example:
Changeling (Minor) - Troll Born
*Bonus Feat: Toughness
*+2 racial bonus to Intimidate checks.
*Fae Vulnerabilities: A minor changeling without Damage Reduction suffers +25% damage (round up) from iron weapons. The troll-born also suffers a -4 penalty to one skill from the following list: Bluff, Diplomacy, Gather Information, and Sense Motive.

Or:
Minor Talent - Precognitive
* Future Sight: A precognitive gains a +1 competence bonus on Armor Class against attacks by mortal opponents.
*+2 competence bonus to Bluff and Sense Motive checks
* Bound by Time: A precognitive suffers a -2 penalty to all Charisma-based skill checks except Bluff.
* Council's Ward: A precognitive can be detected by Wardens and other members of the White Council who are within X feet. Any breaking of the Laws is detectable from a much greater radius.

Things like a Red Court Infected would be a template too, with greater bonuses and much greater penalties. The key would be: are the abilities greatly improvable by practice? Things that are (Wizard, Sorcerer) are classes; things that aren't (Red Court Infected), or are profoundly limited in how they can be improved (Minor Talent) are templates. I'm tempted to say that White Court Vampire is a class, since there seem to be greatly varying degrees of skill/power in the use of the vampire abilities, but it might be both (a template for the base abilities, and a class for refining the abilities.)

EDIT TO ADD:
Of the types we've seen so far:
Classes:
Wizard (Basic Class)
Sorcerer (Basic Class) - may be the same class as wizard with different options chosen
White Court Vampire (Basic Class)
Werewolf (Advanced Class - but with low prerequisites)
Faithful (Basic Class)
Faerie Court Knight (Advanced Class)
as well as the basic classes from D20 Modern, for plain mortals and minor talents...

Template:
Changeling (actually several templates depending on Fae parent)
Lycanthrope
Minor Talent (actually several templates depending on specific power)
Red-Court Infected
White-Court Born

A terrible creature, the most potent of the Walkers, a powerful knight among their ruling entities. 

This sure sounds like it's implying that "Walkers" are a particular subclass of Outsiders - maybe a different type of being, or maybe just a job. I wonder if the Walkers are equivalent to the "knights" of the Outsiders?

For a smog-Outsider, I might use "He/She Who Darkens The Sky".
