Prism Psynergy series

The Prism Psynergy series is one of the strongest groups of Mercury Psynergy available. It receives heavy usage in both games, as each level of the technique is very powerful for when it learned and retains much of that power for a long while afterwards, even outdoing the Jupiter-based Plasma Psynergy series it is paired with in the Hermit and White Mage class series, at the cost of narrower range. Being available to those two class sets and the Pilgrim (Mercury) series, it is available to all Adepts except Isaac, Felix, Matthew, and Himi.

Availability
Prism is learned at Level 6, Hail Prism is learned at Level 20 by the Pilgrim (Mercury) and 22 by the Hermit and White Mage, and Freeze Prism is learned at Level 52.

Other
Crystal Powder: Emulates the Hail Prism Psynergy for Mercury damage to multiple enemies.
