Going into the end and beating the dragon is a one-time per whole server thing. From experience this happens at most 3-5 days after the server goes online. Fastest I've seen someone do it is 1.5 days, and I'm pretty sure it's possible to get there faster if you focus on it. After the dragon is killed, you can get infinite enderpearls trivially with a 2 high ceiling and a stack of athames, even without building any sort of elaborate trap. EE or not, I will always consider enderpearls to be easily farmable and available in virtually unlimited quantities.I wasn't thinking about iron, but seriously? You're talking about getting to the end that early?
If you still consider pearls rare, I will gladly exchange them to you for other to you similarly rare stuff.
