Different end mobs and golems

I feel like you should add new end mobs to make it a little more dangerous after you defeat the dragon and go through the end gateway. Maybe a end golem as well, that guards a new structure in the end, like the temples but bigger and harder. You could also add an amythest golem in gyodes, because they are too easy to loot, and if you are going to add that, add new amythest crafted items as well, idk what, but something. And maybe make the desert wells have a secret room or an actual purpose.
