Both (Lumina & Umbra) spawn on the following maps:

Scorched Earth, The Center, Ragnarok, Lost Colony, Valguero, Extinction, Astraeos

Lumina at day, Umbra at night.

This is literally a knockoff light fury

The idea incubation temperature for lumina is -85°.

Can confirm they do spawn on scorched near wyvern trench

I think that these are the female version to the umbra but idk

They also spawn on scorched earth

Is only on Ragnarok hard to find this one.

What even is this thing? Like what is it?

I never heard of this but i am the first tip
