Yakshini is an enemy in Final Fantasy XIII.
At the beginning of the battle, Yakshini will use its Catastrophic Dance to inflict Deprotect. When it gets weak, Yakshini will use its Frenzied Dance to bestow Bravery on all enemies. It takes half damage from all elements besides Water and Earth, to which it's weak against.
Yakshinis, also called yaksinis or yaksis and yakkhini in Pali, are mythical beings of Hindu, Buddhist, and Jain mythology. A yakshini is the female counterpart of the male yaksha, and they both attend on Kubera (also called Kuber), the Hindu god of wealth who rules in the mythical Himalayan kingdom of Alaka. They both look after treasure hidden in the earth and resemble that of fairies.
