Hi everyone! I just play this game about one week. I try many times but i cannot rebirth. Can you teach me how exactly rebirth work? Thanks

(Sorry because my English is bad)

so there are mechanics in the game which are important to rebirth here it is!
1. Lona must give birth to a child (depending on what kind of being impregnates her she will be reborn a mix or that race)
2. im pretty sure giving the babies to elise negates your rebirth so keep the baby in your inventory and alive
this is how i rebirth but i would recommend the wiki

https://lonarpg.fandom.com/wiki/Cross_Breeding_and_Rebirth

If Moot (long ears) baby then you need to do nothing. 
If Deepone (body odor fish person) then you have to go to fishtopia caves and find the deepone mother and talk to her

If abomination (red eyes and sickly) then you have to speak to the fortune teller. 

Abomination baby is the best, but the hardest to get. Lona has to give birth to 2 abomination babies and sell them to Elise (Sell option NOT barter) for it to become an option.
