Due to her power, Sierra is an extremely diversely skilled and well rounded individual. She has so much time during the day that her opportunity cost for doing things is far lower than most.

Media- Sierra is extremely well versed in all forms of media- movies, books, magazines, video games, comics, you name it and she has almost definitely seen it, read it, or played it and will understand the reference. She is also a massive history and sports buff. If you go up against her on trivia night, she is incredibly sorry for the massive ass whooping you are about to receive.

Languages- Sierra is proficient in reading and writing in eight languages to an advanced degree: English, French, Spanish, German, Mandarin Chinese, Japanese, Russian, and Arabic. She is capable of reading dozens others to a fairly basic degree, and cannot speak them having found the other aforementioned languages more intuitive to her.

Music- Sierra is quite literally her own band, and she is capable of reading, writing, arranging, and performing with several instruments such as the keyboard, electric and acoustic guitar, bass, drums, all sorts of brass and wind instruments, and other stringed instruments. She is also a vocalist- being an alto, and while she's good she is not particularly show stopping or abnormally good.

Art- Sierra is an exceptionally well practiced artist with both pen and pencil as well as paintbrush. She regularly does paintings or sketches of various people, places, and things preferring to draw what she sees instead of what she imagines. Other forms of art she regularly partakes in as well, such as photography and dancing.

Cooking- Sierra is a master chef.

Chess- Chess, and other strategy games are some of Sierra's favorite pastimes. She regularly plays against herself and other people if they are willing to go up against her.

Technology- While not quite as common a skill for young women in her age bracket, Sierra's ever inquisitive brain has taken a liking to anything relating to computers and software. She can build computers, solder electronics, and code entire websites. She is certified for Microsoft Office, the Adobe suit, and is an excellent video editor. While she is not certified, she is extremely experienced in IT and often finds herself diagnosing and solving advanced and simple technical problems.

Well Studied- Years of reading has led Sierra to be extremely knowledgeable in a plethora of subjects such as biology, chemistry, anatomy, history, zoology, Astonomy, physics, pathology, psychology, among many other subjects. She is by no means certified and doesn't regard herself as a substitute for a licensed and practiced individual, but things come in handy here and there.

Naturalist- Years of curiosity has landed her in the wild and in some fairly compromising positions. She's fairly adept as an outdoorswoman. Years of camping, bird watching, hiking, fishing, and generally exploring has made her an excellent survivalist. She is very familiar with most species of animals and plants in all areas of the USA and knows all of the constellations and other celestial objects in the sky. In edition to this, she is also experienced with bow hunting- although she is far from an expert huntswoman.
