I don't think so, he's mostly active on the discord server.

He checks the wiki

Well, It makes sense Cube Kid does check the wiki, He can take inspiration from fan ideas if he doesn't have any. Not saying he doesn't have any, his books are full of good things.

Most of the fan stuff is super OP, so not great for inspiration

Well yeah...

Makes sense, though it says to make your creations "not too OP."

I guess people like OP things. So they imagine OP things.

Why can't have someone come with a couple simple ones? Heres one I just thought of on the spot:

Name: idk

Description: Every animal in a 10 block radius comes to you for 30 seconds

Simple. I like it.

Basically random abilities, like "You have a 25% more chance to crit for the next five seconds."

Idkkkkkkkkkkkk
