Witches

A witch is person with the power to affect change by magical means through the practice of witchcraft. A witch can be either male or female..

Characteristics
Whilst anyone can practice magic, witches (normally, exceptions do exist) have greater knowledge and power over harnessing mystical forces. Witches have existed for many centuries, and found in many races lore. The source of there power is stated to be most commonly demons, there has been one proven case of this (and three possible but unproven ones). It is also possible to learn to be a witch without outside help, as several witches have been shown to be self taught, in fact white witches have been stated to have nothing to do with demons whats so ever.

Witches commonly form coverns, but this is not a necessity. They are also often social, and meet with other witches.

Some Witches have Familiars however this is comparatively rare.

Although Witches aren't always evil, they often turn evil (or atleast have momments of disragard) as the power corrupts them, Dean compares it to crack, stating once the get it "its surprising what they will do".

Powers and Abilities
There are significant differences among powers of different witches, with some being powerful enough to even stun low level Leviathans, while others can hardly even defend themselves against human attackers. As such, not all witches have the same powers. Below is a list of powers demonstrated by different witches over the course of the show. It appears according to James, that some of if not all Witch's powers are block due to iron. As he couldn't astra project under his iron chains were removed.
 * Reality Warping - Some are able to alter reality through magic, but this is usually only to a very small degree.
 * Spell Casting - The act of changing and/or controlling events through the use of charms, hexes, rituals, etc. Powerful witches like Don Stark can easily cripple a Leviathan. It is unknown if they can kill a Leviathan, but it is heavily implied they can not. Witches comonly require rituals and objects to direct the spells, such a Hex bags, or enchanted objects like Tarot cards or coins.
