The illusion interest has been implemented, but it was already Awaiting Endorsement by the time I left a comment on it highlighting my desire for a rename.
The Illusion thing's about doing magic. It's one of those magical interests, and it talks about illusions who "may convince others to act for them", which means it isn't stage tricks. Can we rename it to Illusion magic? "Giving/Receiving Illusion" also doesn't make semantic sense, but "Giving/Receiving Illusion magic" makes a little bit more.
(Usually, someone pointing out the need for a rename is enough to put it into Needs Discussion, and as far as I can tell, only one person - not me - endorsed the interest. So hopefully my issue can be weighted fairly?)
