Parts of the diff look wrong. Will reopen once I fix that.

Looks pretty good now. Im not sure about my if/else tower but I don't know what to replace it with, dict wouldn't work great here.

[Sigmanificient]

does this big elif chain is actually any faster?

[Lunarmagpie]

No idea. It's there now since Mentionable runs two different functions so a dictionary doesn't work.
The optimazatiom comes from me removing unnecessary request to the discord API.
