Given how the darkness effect is more prevalent from nodes, and how more dangerous fighting the Horde becomes with the Darkness Effect, I think a potion of Darkness Resistance should exist to ease on taking out nodes.

My take on a Potion of Darkness Resistance:

• Needs a Crying Soul as the brewing ingredient, base potion lasts for a minute.
• Can be upgraded with redstone to give 3 minutes of resistance.
  

I will consider this.
