Fury Rune

The Fury Rune (怒りの紋章, Ikari no Monshō) is a rune which appears in several games of the Suikoden series.

Information
This normally passive rune would enrage its bearer during battle. It would drive the bearer into a frenzy, having them deal much more damage in battle. As such it was useful for those who fought with physical weapons or their bare hands, allowing them to overcome their natural limitations.
