So in Skin Game when Harry was talking to Murphy about the Genoskwa he mentioned that it used earth magic the same way the Forest People used Water magic. I did not understand what he meant so could some go into more details if they know because all I got was that it was a form a defense but I do not see how that could not be water or air magic as well.

Okay just about finishing up my re-read of the Dresden Files and just have a few quick questions/clarifications.
1. What is the difference between Carlos's entropy water magic and Entropomancy that the Fomor and other magic users use?
2. I was reading the Dresden Files RPG Our World, I play it with friends, and it mentioned Molly Carpenter in Small Favor was trying to learn another element evocation aside from Spirit and Wind. Aside from the spirit shield at the beginning I do not recall any other element she tries to use unless I overlooked it or it is in another book?
3. Lastly, do the winter or summer mantles give you the ability to do magic in general or only a certain kind of Fae magic? Molly and Harry can do things with magic that does not involve their mantles, and I was curious if Fix/Lloyd Slate or Maeve/Lily/Sarrisa could do magic as versatile as they could.   

So after reading A Fistful of Warlocks I believe that I have found out what Cowl's necromantic abilities are as aside from the Darkhallow he has not used any so far in the series. First all of the apprentices seem to have a similar skill set with evocation as Grevane and Corpsetaker have both used lightning and kinetic/force energy in the stories they have appeared in with Cowl having the most gift in force magic. In the thaumaturgy side, Grevane used the more traditional necromancy, raising zombies as his forte while Corpsestaker used ghosts and spirits, both abilities that Kemmler himself was a master of. The last ability that he was most well known for was rising from the dead multiple times. Previously Kumori told Harry that Cowl has contended with death curses before and as he seemed the most powerful and more importantly intelligent of the three, he most likely adapted Kemmler's most useful ability while maintaining a disdain for the other sides of necromancy. Knowledge is power and this also gives credence to the Simon is Cowl theory as he would have no need to fake a death curse if he actually died and he would be able to be more active in the Black Council as events in the series have escalated to say the least.

While there has been examples of elemental combat magic  throughout the series that Harry and others has used, water magic has not been seen in detail. Do you think with enough time and preparation he could use the entropy/disintegration blasts that Carlos uses, and in the case of the premier water mage in the world does Listen to Winds use a similar form of offensive water magic?

1. In Turn Coat Listen to Winds mentions to Shagnasty that Harry nearly beat him without knowing the Dine yet alone the Old Ways. What other Old Ways was he referring to, since the Dine aka the Blessing Way seems to qualify as tradition in the oldest sense.
2. What did Listen to Winds and Ancient Mai do while the others were busy fighting the Grey Men? It did not seem like they accomplished anything notwithstanding the thrashing Listen to Winds gave to Shagnasty.

So Vittorio Malvora and to some extent Lord Raith have used Outsider magic but how it is used varies differently, enhancing the formers power, and removing magic on the latter. He Who Walks Behind is the source for both of these so is there a reason for the contradictory powers? And on another note Cowl has been said to use Outsider magic but I cannot remember, where did he use it in White Night somewhere or is this just speculation I took as fact?
