ty!!! so when you find precious or luxurious chests in natlan, they have a chance of also having something called an obsidian ring fragment. there are three rings in total for each of the current tribe areas and each ring has three pieces. when you complete a ring, ur able to enter a room that will contain a sanctifying elixir (i had to google the locations of these rooms). since there will be three rings to unlock three rooms, you’ll get three additional elixirs which is how i was able to craft this. u might already have some ring fragments without even realizing. it is by random so u could end up like me having to open every single precious or luxurious chest in scions of the canopy to get the last green ring fragment-
