Killer Rune

The Killer Rune (ひっさつの紋章, Hissatsu no Monshō) is a rune which appears in several titles of the Suikoden series.

Information
The Killer Rune increases the concentration of the bearer during combat, allowing the wielder to spot enemy key points. This allows the bearer to deliver a critical hit to the enemy's vital points at a greater frequency than usual.
