for anyone who is unfamiliar, here is what wiki had to say and this is the most accurate power-description i have ever read for her
Tantu Totem: Vixen wields an object called the Tantu Totem, a fox-shaped talisman, which enables her to tap into the "morphogenetic field" of the Earth, sometimes known as the Red. This allows her to mimic the abilities of any animal she can think of, by simply focusing on a specific animal abilities and then drawing it directly from the field. She has demonstrated the ability to hold onto the Morphogenetic traits of an entire forest of animals.
So far Vixen has been able to use:
Animal Mimicry:
the telepathic and physical abilities of Gorilla Grodd,
the flight of a hawk,
the swimming ability of a dolphin,
the speed of an cheetah,
the wall-crawling of a spider,
the jumps of a cricket,
the constriction of an anaconda,
the strength of a bull elephant,
the senses of a wolf,
the agility of a monkey,
the debilitating shock of an electric eel, and
the ability to spit venom like a cobra.
Enhanced Claws: Vixen's claws are particularly sharp and tough, enabling her to rend through a variety of substances, such as fabric, wood, even soft metals and cinder block with ease. Her claws are magically enhanced and have drawn blood from individuals who are consider highly durable like Geo-Force and Pre-Crisis Superman.
Animal Metamorph: Occasionally, she has been known to physically transform into animals - for example: she has shapeshift into animals, such as a wolf, a great horned owl, and a cougar.
Enhanced Healing: The totem even allows her to heal bruise and wounds within seconds by simply touching it or using the healing abilities of an earth worms.
Morphogenetic Field Energy Manipulation: While the full extent of Vixen’s control over the Morphogenetic field is unknown, she has on occasions drawn pure energy from it and displayed this energy as a force field and energy claws. While in cooperation with Animal Man and the woman known as Tristess, she creates an entire universe
Limitations: It is unknown what would happen if Vixen tried to use her magical abilities on an alien animal, or if she would gain access to the Morphogenetic field of another planet.
