Please read the comment before commenting yourself. We already explained that this doesn't always work.If your worried about someone respawning when your trying to get there egg, Step.1 kill them, Step.2 while there respawning, block your self around there egg with whatever block you have, Step.3 break there egg while there not punching you. Step.4 if there smart and go get a pickaxe, break your protection layer, kill them again, while they respawn, go to a differ island and buy obby to block yourself in, it takes more time but at least it works.
But, for the sake of it I will just write it again over here especially for you since you are somehow unable to read previous comments;
1. Egg cracker kit. Sandstone will never work, obsidian takes very long to get.
2. If the spawn of them is literally right next to the egg (like on the map instruments), It just doesn't work. (especially if they have egg cracker kit)
3. To make it even worse, the spawn protection system is so fornicated up that they are able to hit you but you aren't able to hit them.
