I noticed that when battling and damaging the Royal Jelly, his crown begins to break halfway, and then completely when phase 2 kicks in, just like the Ice Queen does in the Shadow Lair counterpart, due to the Shadow Lair update or so, I believe. Didn't anybody notice that? If anyone knows of the Royal Jelly's changes, but didn't edit the wiki's pages about it yet, please do. Thanks!

I'm fairly sure it's three phases anyway, because the enemy spawning changes once the crown is slightly fractured.
