Baby Carno

1st Step
Rebirth with a rebirth multiplier that is at least 69 sextillion (6.9e22) times higher than your current multipliers. A popup window will appear with some text and you will obtain a 'Weird Glowing Rock'.

2nd Step
Use a fire alchemist to craft the 'Weird Glowing Rock' for 69 hours. It will hatch into the Baby Carno! If you can't see the recipe on your fire-alchemists, ensure that the Weird Glowing Rock is not equipped on a dungeon team and you scrolled all the way up.
