I'm planning on running a Monk/Cleric (14 in Monk and 6 in Cleric, if my character survives that long, I haven't yet multi-classed into Cleric), and we've come across a few enemies that are able to blind members of our group, and as a halfling, I don't have the benefit of darkvision (which is fine, we have members of the party who are able to light up the room).
But with some of the context out of the way, Detect Evil and Good states:
For the duration, you know if there is an aberration, celestial, elemental, fey, fiend, or undead within 30 feet of you, as well as where the creature is located.
As I wouldn't be concentrating on another spell, I should be able to make unarmed strikes while using this spell, but that leads to the question:
Would I still have disadvantage on my attack rolls (while blind) as a monk, if I know their location via this spell?
