Each house has two abilities associated with it.  The first physical, the other mental.

Gryffindor:
It's no secret that Gryffindor houses some of the best adventurers around.  While the other houses might be more proficient in various other ways, it's often those from Gryffindor who find themselves in the spotlight.  Their courage and daring is legendary, though they are often headstrong in their methodology.  The signature ability of Power reflects their ability to meet challenges head on -- much like two rams butting horns.  Their signature ability of Luck reflects the nature of the strong pulls of fate on the Gryffindor.  For better, or for worse.

Luck - A measure of the quality of one's general fate.  An exceptionally high luck shows strong fortunes while a comparatively low luck might be indicative of an ill omen.  Feats involving luck might include: Games of chance -- making a guess -- succeeding at surprisingly difficult tasks that would otherwise be impossible.


Hufflepuff:
Frequently considered to be the weakest of the houses, the Hufflepuffs are more powerful than one might think.  Where they lack in strength and wit, they make up for in steadfast determination.  Although a competitive drive is decidedly lacking in the Hufflepuff mindset, there is no doubt about the ability of a determined member's ability to succeed.

Ravenclaw:
Ravenclaw is host to the spirit of learning.  Whether it be academic pursuits, philosophical teachings, or simply functioning knowledge of the world about you, Ravenclaw can provide.  Above all else, the Ravenclaws value wit, wisdom, and knowledge -- both practical and mundane.  While this may leave them lacking in some physical aspects, they more than make up for it with a stunning array of knowledge to use for their own benefit, or their opponent's detriment.  The signature ability of Perception reflects the studious nature of the Ravenclaw, always ready to take in information while the other signature ability of Intellect is reflective of the staggering knowledge and applicable understanding of information gathered.

While in some cases these can be definitevly negative traits, the Slytherin have embraced these values, sometimes working for the greater good.  Like them or love them, there is no doubt that a particularly motivated Slytherin is a force to be reckoned with.  The signature ability of agility represents the Slytherin's tendency to be slippery or difficult to catch as well as being opportunist -- always seeking the right place, the right time, and the right angle to succeed.
