SCH cannot close Light or Darkness, because you'd need a L2+ property "WS" to do that, of which SCH has none via Immanence.
You can make Distortion with Immanence and close Darkness with Retribution/Omniscience/Shattersoul though...
Light would require a Club, closing with Realmrazer or Black Halo.
Yea, well I still trying to see how this guy made LIGHT with realrazer.
Sure Fire, thunder, black halo works to light. But how did he make light with realrazer?
