All alchemy starts with Captchalogue cards. Each player has a SYLLADEX in which they have their cards. In these cards, they can have most normal items, with some exceptions being massive objects, players in their normal form, and other edge case items. The way you access your items is by using the FETCH MODUS, and each MODI have specific rules that it must follow.
Current Modi include:
Meowrage: Guessing MODUS- can you guess what this one does?
SYB: Duck Hunt MODUS- you must play DUCK HUNT in order to access items
BYS: Super Mario Brothers- An As of yet unseen modus.
Terezi: Scratch and Sniff- One where you scratch and sniff what item it is
And the rest are unknown characters, or unknown Modi.
As the name suggests, there's a captcha code on the back of each Captchalogue card.
