Shiva is a summon that is of the Ice element.

Etymology
"Shiva" (also spelled Śiva) is the name of a Hindu god who once saved the world by consuming poison; this turned the skin on his neck and throat blue. Despite the fact that he is male, Shiva can merge with his consort, Parvati, to become Ardhanari, an androgynous god of duality.

Shiva is known as the "god of destruction" in Hindu mythology; he is one of the three deities that comprise the Trimurti (Hindu Triad). It is believed that Shiva periodically destroys the world and then recreates it.
