Invisible Ender Dragons

As seen here, ender dragons are made so they cannot have potion effects. I was wondering if this is enforced on the client or server side, and if on the server side, whether this can be altered using some NMS magic. A cursory search of EntityEnderDragon doesn't reveal anything about blocking potion effects. However, someone more experienced may be able find it.

 

Bump

 

We know
-it doesn't appear
-it's not blocked server-side

So we can assume
-it's blocked client-side

However, if you still want to test it,
-Spawn an enderdragon
-Add the potion effect
-Check if it's still there

You can accomplish that without NMS.

 

How exactly do we know it's blocked client side and not served side? I very well may have missed something.

 

Maybe this has something to do with the fact that this is the only multipart entity? No other entity has more than 1 entity that makes it up.

 

Why do you want it invisible? Only for the boss bar? Just keep it at y -35 or something

 

AronTheGamer I could imagine the dying effect (light rays) would be very cool to play with if you can seperate it from the dragon, visually atleast

 

No, this isn't for the boss bar.

Dragon.wings.addPotionEffect ?
