Titania deployed it with great effect against Ethniu and the Eye of Balor. LtW used it against the Naagloshii. Vadderung says part of the reason Demonreach Island is surrounded by water is to reduce the efficacy of magic deployed against it (or something along those lines). Black Court Vampires supposedly cannot cross running water. I think even Harry tried to cross a river to escape the Demon that the Shadowman summons.
I am unfamiliar with the video about Dragons. I had a brief look but couldn't find anything beyond when Dragons will next show up and their use as terraformers. Do you have a link?

If that's the case though that Ferro and his compatriots are merely the Western team, what are the Eastern ones up to? I thought though that there were only 3 or 4 Dragons in the whole world (not including the lower-case dragons who are merely beasts and servants created in the "image" of the big D Dragons).

Interesting follow-up idea. If the Dragons are also the guards to reality (or at least the pillars holding back the tide) what happens when they are gone? What happened after Siriothrax died I wonder, and what things have been possible with his death?

I'm linking to the Reddit post because their link jumps to the part about dragons.

In summary, he says there were three left on Earth and Michael killed one of those. Someone asks about Eastern dragons and Butcher says the Eastern dragons are doing their cosmic job, and the Western/European dragons were the disgruntled workers that got involved in mortal affairs and tied up on Earth.

Power within the Dresden Files is just like real life in that it isn't one thing.  One person can be powerful because of money, another because of fame, another because of fighting ability, and another because of firepower.  The list goes on.

The Black Court is the strongest of the Houses in pure brute force, and magical capabilities.  These qualities made them formidable to be sure, and feared, and hated by many.  As strong as they are, they have major flaws. 

1. They are deathly vulnerable to things that aren't difficult to obtain. 
2. It is virtually impossible for them to blend in with humanity.
3. They are devoid of kindness, honesty, or trustworthiness.  They have no real friends or allies.
4.  Although they are capable of intelligence, and cunning, it isn't a defining quality of the species.

The White Court is not on their level with regards to brute force, and magical power, but they are very dangerous.  As I mentioned earlier, there is more than one route to power.  The White Court uses intelligence, guile, misdirection, manipulation, political connections, and wealth. 

The White Court could never have faced the Black Court in a head to head fight, but they didn't need to.  They took sensitive information about the Black Court's exploits and made it very public.  Then all they had to do was sit back and watch as all the people who hated, and feared the Black Court hunted them down.

The White Court brought them down without ever putting themselves into harms way. 

A good comparison would be Winter Knight Harry Dresden vs vanilla mortal John Marcone.  Sure Harry could absolutely destroy Marcone, but Marcone wouldn't face him directly.  He'd have someone pick Harry off from 500 yards with a 50 cal. 

So the White Court might be underpowered in some ways vs the Black Court, but who's on the run, hiding, and facing extinction?

We're basically agreed. What the Wamps lack in raw power and ability, they make up for with other resources. I have no problem acknowledging that Titans are more powerful than wizards, and also acknowledging that Harry beat a Titan when armed with the right resources.

But the Blamps' greatest weakness isn't garlic or holy water or sunlight, or even that they don't play well with each other or others. It's their age, and the time it takes for one to gain enough power and influence to enact change.

We've seen the same thing with wizards and Ramps. The elders are slow to adapt to new ideas.

If a modern human could be turned into a Blamp and given enough power and authority to enact change, then they'd be terrifying.

I expect we might see just that in the near future with Yoshimo, Wild Bill, and/or Chandler. If modern wizards with power and experience fighting a modern war with modern weapons are given authority in Drakul's ranks, then we could see a formidable Blamp army in the near future.

Blamps with enchanted cloaks that holy water rolls off of like blood off Warden cloaks. Wind charms created by Dark Yoshimo that keep a breeze blowing around Blamps to prevent garlic from hitting them full on. Renfields trained by camp kaboom veteran Wild Bill, covered in body armor and modern weapons and working like a military unit to protect high value assets, or crossing thresholds to drag victims out of their homes.

That's assuming the Blamps haven't been stockpiling items touched by True Love from their victims to use in an assault against the Wamps when they're ready. Imagine them collecting souvenirs and testing them on a captured Wamp for a hundred years.

Given the right mindset, the Blamps can be just as resourceful as the Wamps.

I'm thinking when Lara was reduced to a barely animate skeleton and devoured Madelaine. That's a hellacious amount of damage to take and be visibly healing from.

A strong, fully-fed White seems to have Wolverine-like healing- at first. When sufficiently injured, they go feral, and also feed indiscriminately. Don't underestimate that.

I think they're very formidable against humans and average wizards. But against a Blamp, that they presumably can't whammy or feed from? That exceed their raw strength, can also take massive damage, and can feed from them? Not as formidable.

Ramps seem like wimps, so I'm not going to argue against a Wamp taking one on. But unless the Wamp is specifically geared up to take on one, I don't see your average Wamp taking out your average Blamp.

As I recall she had several ladies with her, and I bet one doesn't onto Lara's kick ass team unless you can really kick ass.

Sure, I bet there's a dozen members of the family that are well fed and well trained. But those same high-level Wamps were broken like toys by Shaggy in TC. In their place of power. Across their threshold, and whatever wards they had in place.

Likewise, Eb could have taken Lara out at the end. The Wamps are formidable up close with humans that they can whammy or enemies they can beat to a pulp. But their top tier against top tier wizards isn't a fair fight, much less anyone else with power.

Yes, however, this is only taking into account recent events. Before, when the White King actually in charge, he didn't have many of the connections Lara has (or none that I know of). Just look at the old muscle Harry called them Barbies/Ken Dolls. They were immediately upgraded to much more threatening and intelligent individuals after Lara took over. Lara has made the W Court the powerful force it is today, not W Court powers (yes, powers may have helped, but as the book says, W Court sex slaves made bad tools).

That was during Harry's lifetime, though. Raith had stopped feeding upon his birth, and was preserving the tank. We can assume there weren't huge changes in his behavior so as to go unnoticed, but it seems likely he couldn't do all the things he could have previously done.

Crossover method is easy. Bob established that every universe is out there somewhere in the never-never, just really far away. Even Spider-Man.

So Harry can get anywhere, and it can be via mistake using his mom's amulet and ruby.

As for what series, I'd like to see him with Doctor Who. His murphyonic field messing with the TARDIS and sonic screwdriver, Who breaking the law against time travel, Molly there flirting with the doctor only to realize she's found the only other man in existence that will never actually be with her... Lots of potential for hijinks.

Simple question.

If yes, what coin and Fallen would you want to see him with? What would his battle form be?

If no, then that's boring, but okay.
