Effects: 

All rune cannon attacks and skills cost 25% less Soul to use, rounded up. Apply this reduction before any other effect that reduces Soul costs.

This additional damage ignores all armor, Spirit defense, and magic blocks. This Vitality damage is treated separate from any other rune cannon damage.
