Within Deeper Darkness can auras be seen from spells like Detect Evil or Arcane Sight? If Darkness or Deeper Darkness is casted within a Bullseye Lantern or similar light directing device can the darkness be directed?
1) I would have to say yes. The detect spells are very specific as to what blocks their detection and darkness isn't listed.
2) Darkness functions the same way as light (meaning you can cover it up like a torch to negate the effect). Best to think of the darkness spells as negative light. So yes, a Bullseye Lantern should work.
