Lead the forces of light to victory!
Henzell says...
  1. A {scarf} ego that reduces player LoS by 1, but also reduces spellpower (not in 0.27+), and stacks with kobold's {nightstalker} mutation. The unrand {robe of night} has a stronger effect, reducing LOS by 2. The unrand {ring of shadows} has an {umbra} and does not reduce LOS.
  2. Prior to 0.26, was not a scarf ego, but the effect was available via the {darkness} spell.
