They spawn on extinction.

They also spawn on Ragnarok.

20:26 is night time for dreadmare

To the guy who said where to find these: they are close to the right side of the map on Ragnarok

They are on Extinction in the southern part of the wasteland between the Sulfur fields and the desert dome

DREADMARES SPAWN ON EXT IN THE WASTELANDS STARTING AT 20:00.

I had most success finding pairs in the sulfur pits near the boarder/sunken Forrest, outside the snow/desert biomes.

YOU CANNOT PLACE ALTERS IN THE CITY OR BIOMES.

For a safe boss battle with the dreadmare/stallions, I use that giant flat pointy rock outside the sunken Forrest. Nothing spawns there.

It does fly around so just stay in place and wait for it to come to you. Once you fight it multiple times you have to click the alter for it to spawn.

I’ve seen one in extinction but it was glitch and had no collision and couldn’t take damage I didn’t know what was happening

You can find these devils on scorched earth around the area of Latitude 52.9 and Longitude 81.7 at least that’s where I found mine and don’t forget they come out at night!!!

Parasaur will ping its location even during the day then build a cage surrounding it also turrets don't lock onto it at the moment as of 10-31-24
