Where do Nightmares spawn?

[Choco]

I can't seem to find any. Where should i be looking in the overland spawn.

[Panthor the Hated]

theres one in cyclops valley


all nightmare spawns should be in t2a

[OhSnap]

The only spawn areas I have personally seen and can verify are Cyclops Valley and The Oasis. I've heard they also spawn at Terra Sanctum and East of Delucia. With that being said, the spawn rate is quite slow for them, and you may travel to these places several times a day and still not see any wild nightmares for some time.
And as Panthor said, the above stated areas are all in T2A aka Lost Lands

They used to spawn here, but I haven't verified it since last Fall. (Areas Highlighted In Red)



In the past, they spawned in several locations and this has lead to some confusion as to where
they actually spawn at. As of last Fall I could only verify the 3 red shaded regions as spawn
points for the Nightmares. I do not remember the spawns being like this on my OSI shard and
have pushed to get them changed. They could have been changed already, who knows. This is
where they were this Fall, though.
