I had the idea of making the elytra be basically a universal equipment for any of my set effects, meaning that every set bonus that existed would also work with the elytra. This, of course, makes the item have a giant tooltip when I load the world.

I also tried using crafttweaker to remove the tooltips of the elytra but it doesn't seem to work, so I'm stuck having to make a duplicate of every set bonus in my modpack with hidden tooltips, so the elytra doesn't have the tooltips and still manages to have the set effects.

If there's a simple way to implement hiding tooltips for individual items in a set bonus, that would be a huge time saver.

Like a wildcard item to complete any set huh? Interesting use case. I'm in the middle of a big Set Bonus update (which is why the other recent-ish suggestion-issue hasn't been released yet), so it might not be immediate, but I'll see what I can come up with.

If I don't think of anything else, it will just be a blacklist item filter in the client settings.

This is now a thing in the latest release (1.12.2.036)
