  • The fact that Sans is obtained by using the Disc means that the abilities stored in that Whitesnake disk are Sans'
  • Sans has E in Destructive Power but is still one of the strongest specs, this is because Sans only deals 1 HP per attack but deals multiple hits and also leaves a poison damage.
