the red crystal

this new type of end crystal the red crystal and will work a bit like a turret which will attack zombie's, skeletons, pillagers, etc. basically it attacks anything that is hostile. you craft it by putting an ender eye in the center of it with four end crystals and it deals 3 hearts of damage each second. It also takes 5 hits to destroy but you can fix it by right clicking with a glass pane. If you name it something like pig it will only target pigs this mechanic also works with player names. The crystal can also spawn in the end and it will only attack you making the ender dragon fight harder. You can technically already make turrets but it only works on players. I also thought of another idea to go with it a staff with it which will shoot the beam doing the same amount of damage and has a cooldown after letting the beam go but I also don't know if its a good idea so I'm fine if doesn't get in game but if it does its crafted by using two sticks and the crystal diagonally. So this is a nice suggestion to give to any dev reading this
