The Rivel (WillPower)
The Rivel AKA WillPower, is a special type of Soul-Related energy that manifests within those who have strong Wills and/or Passion. According to Balit, The Rivel can be channeled in various ways (Such as Lightning, Fire, Magma, etc), and can be channeled through both Bodies and Weapons. Both Balit and Boss have used The Rivel in combat. And eventually, Varbi does as well.
