I Googled and it said it doesn't restock so.... ; 3 ;
Where do we get potions in general?
For the Glade Potion, you can either buy one from user shops directly. Or you can take an Ornate Floral Pitcher to the Peka Glade from 8-9 AM and 8-9 PM Subeta time. Right now the pitcher is cheaper in user shops, so I would go with that method.
Potions and elixirs to change your pet restock at the Apocalyptic Apothecary in Darkside.
Wow it's nearly 9 million though! ; 3 ;
That's not gonna happen for me...
You can always save! Making sP isn't too hard around here, try doing some quests. That's one good way. You can add a sidebar widget to keep track of them by going here and adding the one that says "Quests". There are also some other things you can add to keep track of stuff.
Also since you're new, I'll go ahead and tell you about Subetalodge, which is a fan site that's really good for looking up item information and stuff like that. They sometimes have notes for items with special information, and lots of other helpful stuff.
