Sorry, the Endermen screamers. In bobsky's XP trap I legit have to turn my sound off.
Shulker boxes are like extra inventories you can carry around with you. Carry them around in an ender chest and you're basically carrying your entire life savings with you.
Note: Brad's xtra recipe for shulker boxes (using turtle scutes) does not
work in 1.15, so I had to risk entering the End in order to get my preciousess.
