Smoldering Pearl

To obtain a Smoldering Pearl, you need to kill Pyro Hypostasis in the Inazuma region on any World Level. Bosses are automatically Lvl 36 on World Level 0, so it is recommended to have your Characters at roughly the same level as the boss or higher.

To get the rewards for defeating this Boss, you must spend 40 Original Resin. Though if you have Condensed Resin stored, you can use this and get double the rewards.

To find the Pyro Hypostasis, you can open up your Adventure Handbook, head to the Enemies Tab, locate Pyro Hypostasis, then click on the Navigate button. The game will show you where the Boss is on your map.

A crystallization of a Pyro Hypostasis that constantly emits heat. Even the burning flames shall one day grow cold, and even the ashen firewood can will itself back into a raging blaze. It must then be the will of the world that Pyro Hypostases should constantly cool down and heat up, much like the universe teems with endless life... until the fated darkness shall one day descend and bring it all to naught.
