A very powerful witch that has been around since the 1600s. Among the most powerful witches. After training throughout her life, she has mastered and collected a vast arsenal of spells and other magical objects, which vary in complication.
Abilities and Such
Witchcraft - Being a witch, Rowena is very experienced in the use of spells and hex bags. She even has the ability to create some spells of her own (Defigere Et Depurgare). It is unknown whether or not the Attack Dog Spell is of her making. She also capable to cast a spell that capable to obliterate a human with ease. Her magic is strong enough to affect the King of Hell and a fallen seraph.
Immortality - Rowena can live for a very long time if not infinitely. She has lived for at least 300 years, if not longer.
Hex Casting - Due to being an old talented witch, she has absolute knowledge of hex bags, and are said to have taught Crowley how to use spells and hex bags back in the 1600s.
Dream Manipulation - Rowena demonstrated this ability by crafting a spell which manipulates her victim's dreams.
Astral projection - Rowena demonstrated this ability by crafting a spell which projected her awareness outside her body in order to spy on Crowley making a deal with Sam and Dean Winchester.
Illusion Casting - Rowena proved capable to crafting an illusion spell powerful enough to successfully trick Cain.
Reality Warping - Rowena was able to cast a spell so that one demon had a face on both sides of his head. However, she claims that this is merely a parlor trick compared to what she is really capable of.
Curse Removal - Using a spell from the Book of the Damned, Rowena proved capable of removing the Mark of Cain, the first curse. She indicated that she can remove curses even without the Book but was unaware of how to remove the curse of the Mark itself without it.
Power Sealing - Her powers are reduced to a certain degree due to an unknown sealing spell that was casted by Olivette before her expulsion. Although her current powers and abilities are somewhat reduced, she is still very powerful and difficult to defeat. It's not been revealed what she is capable of in her full state.
Iron - Her power was reduced dramatically and blocked when she was bound by iron. She severely weakened when bound by the iron cuff's in Hell's Dungeon. Sam was also able to restrain her using iron chains.
Verbal Restraints - It appears Rowena is unable to cast many spells without reciting an incantation as Crowley's demons were able to capture her with ease after they had gagged her.
Witch killing spell- as a witch she is vulnerable to the witch killing spell.About Me
A "natural" witch, born with the gift of magic
(as opposed to harnessing the power of demons)
Use of hex bags to kill victims
Created a demon killing spell in the 1800's that only she knows how to perform
Many of the spells that she uses are not easily withstood by humans, and cause them to die shortly after being affected. Even simple spells like the servitude spell eventually burn up the human victims, as do powerful ones.
Rowena was formerly part of the Grand Coven, but was dismissed by her superiors as a result of her violent and forceful use of magic. Later, Olivette revealed that her having a child with a non-witch also contributed to her expulsion.
Before her reappearance in the present day, Rowena was briefly mentioned by Crowley. He described his mother as "dabbling in witchcraft" and said that she taught him a few things. However, Crowley did not mention her name.
Rowena is an intelligent, cunning and extremely manipulative individual who takes great pride in her deceit and devious nature, describing it to her equally manipulative son as "who [they] are". Rowena often fluctuates between her mannerisms, sometimes presenting herself as calm and courteous and then suddenly vicious and violent when revealing her true intentions. She is exceptionally ruthless towards her enemies, whether they are people she loathes or disapproves of or someone who has simply annoyed her. She gruesomely kills the demon Raul after denouncing him as nothing more than "filth" and openly suggests to Crowley that he savagely rip a crossroads demon apart and brutally display his carcass for asking for recognition for his work, justifying this as a tyrannical threat not to waste the king's time.
She has also demonstrated that she has no concern for innocent lives as she frequently uses spells that result in their death by boiling their brains and impaling hotel employees to ceilings. She even points out to Dean that using the innocent against heroes like him will play out to her advantage. Furthermore, Rowena is dangerously wrathful as she takes great pleasure in torturing Olivette for wronging her in the past and threatens to burn everything that Crowley cares for when he throws her out.
Rowena is highly ambitious who believes strongly in ruthlessly fighting and striving to gain power for the sake of greatness. She is very carefree and displays disregard and resentment for authority, openly and deliberately defying both Hell and the Grand Coven without fear of the consequences, preferring to use her magic whenever and however she wished. Olivette stated that while talented and skilled, she has always been reckless and egocentric.
Rowena often feigns a warm and sweet disposition towards others in order to manipulate them and gain their trust. Rowena claims to be extremely proud of her son, Crowley, and regrets abandoning him as a child. She states that she left him both for his safety and to further her career in witchcraft which she deemed "no environment to raise a child". However, it is highly implied she never cared for her son as a child, apparently trying to sell him for pigs on one occasion and abandoning him so she could live out her own selfish desires.
While she claims to love Crowley and regularly reminds him that they are family, it is later revealed that she is merely playing on his emotions, using it to manipulate and gain control over him so she can use his position as the King of Hell to her advantage and to further her own goals. Once Crowley realizes this with Dean's assistance and throws her out of his domain, she becomes disowning and berating and shows her hatred for him and her desire to destroy everything around him.
Although genuinely powerful and talented, Rowena's ego causes her to often over estimate her capabilities, both magical and in manipulation. Many of her failures are caused by her underestimating her opponents.
Like her son, Rowena is quick witted and has something of a dry sense of humor. However, unlike Crowley who believes in integrity, Rowena has no sense of loyalty. This is shown when she abandons a demon in Crowley's dungeon after the demon lied for her and helped her gain her freedom.
