How do you breed Illuminant Bat in Palworld?

Put any of the 3 listed parent pairs in a Breeding Farm with a Cake. Each of those pairs produces a Illuminant Bat egg. Pairs marked Unique override the normal breeding formula, so they are the only route for some Pals.

What jobs can Illuminant Bat do at your base?

The work suitability list above shows every job Illuminant Bat can do and at what level. Higher levels mean faster work, and a Pal with no suitability for a job will ignore it entirely.

Can you breed Illuminant Bat on a dedicated server?

Yes. Breeding works exactly the same on a dedicated server, and egg hatching time is a server setting you control. On a DoomHosting Palworld server you can lower it so eggs hatch in minutes instead of hours.
