Illusioners spawning in raids

[crude cosmos]

Hello again! I know I have posted a fair few idea posts, but hey, I have a lot of ideas to post, and dont wanna put them all together as it may be too difficult to do, but this mod would make the illusioner mob spawn in raids

[white vine]

I've got something kind of like this in my mod. When the right spell is active, illusioners replace evokers.
