Spark Rune

The Spark Rune (しでんの紋章, Shiden no Monshō) is a rune which appears in Suikoden and Suikoden II.

Information
This rune produces a mysterious effect where the rune bearer's allies will try and immediately follow them once an attack is made. This rune can be used to have allies attack a target quickly, before the enemy has a chance to respond.

One of these runes were discovered on the body of the Double Head snake defeated in the Sindar Ruins close to Muse City.
