Singing Edge is a magic longspear in Pathfinder: Kingmaker.

Notes

Affected bardic performances:

• Deadly Performance
• Dirge of Doom
• Fascinate
• Frightening Tune
• Inspire Competence
• Inspire Courage
• Inspire Greatness
• Inspire Heroics

For all performances it counts to have either your ability active or being affected by enemy's bardic performance. Exception is Deadly Performance which activates only on negating it's negative effect (This also means the bonus will stay for 24 hours).
