The battle can be difficult if one is not prepared. Shiva will frequently cast Blizzara either on herself or on the Warriors. She can also cast Silence on a party member. Her most powerful attack is Diamond Dust, which can deal more than 500 damage to every target.
The fastest way to defeat her is to have a Mage continuously cast Fira. Summoners should cast Judgment Bolt while Warriors or Monks should use Strike. Shiva will cast Blizzara regularly so be sure to heal when necessary. If Eduardo is in the party, he can support the team with buffs or healing. When Shiva casts Blizzara on herself, her INT will increase for a few turns. She can use Silence to prevent party members from casting spells, making the battle more difficult. However, the aforementioned Diamond Dust is her most dangerous ability. She casts it randomly, but will usually cast it when she is weakened. Make sure the team is healed afterward, strike Shiva with Fira or any other attack that can deal heavy damage and the player can win the battle without much difficulty.
Shiva (also spelled Śiva) is a Hindu god. The Hindu Shiva once saved the world by consuming poison, giving him blue skin around the area of the neck and throat. Shiva is a male god, but can merge with his consort Parvati to become Ardhanari, an androgynous Hindu god of duality. Shiva is the god of destruction along with Vishnu, who is the god of preservation, and Brahma, the god of creation. Together they are the three principle deities of the Trimurti (Hindu Triad). It is believed he periodically destroys the world, then recreates it.
