Types
Every chatter starts as 𝗡𝗼𝗿𝗺𝗮𝗹 type. Types are determined by hidden statistics; whichever stat you have the most "points" in is your type. The factors that change these points are mostly mysterious by design, and intended to serve as a "personality quiz" / "Hogwarts House" sort of thing, responding in the background to normal participation in the stream. It's possible to manually increase your points in a certain type by "purchasing" the relevant type item with Channel Points (earned by watching the stream) with the Fancy Li'l Cakes icon under the chatbox, but availability is limtied.
The most recent non-bot to post in chat has their type displayed to the left of their post on the stream, so all you have to do to see your own type is to post in chat. The command !typecheck [username] can be used to check the type of another user.
The effect of the mighty move 𝗛𝗶𝗱𝗱𝗲𝗻 𝗣𝗼𝘄𝗲𝗿, performed by cashing in many Fancy Li'l Cakes, varies depending on the Type of the user.
