The description of the effect reads:
The Blessing of Darkness fills an area equivalent to what a torch would light, and no light escapes it (e.g., a lantern targeted by this spell would produce enough light for the person carrying it to use, but no one else could benefit from it).
Does this mean that the light is not visible at all to anyone other than the user of the prayer? For example, could a thief use this prayer to operate with the benefit of light while his targets are still in the dark, unaware of the prayer’s effects? I first read it that it produces the light but is not visible from outside its area of effect. Ie. If you were using the prayer to approach the walls of a castle at night, the guards atop the ramparts would not see the light but the party does not suffer from darkness. However, as I am running a Thief now and our Cleric has this prayer, we were discussing the benefits it might have as written in my character’s exploits. So, I am here seeking clarification.
