Travel to the End > kill the Dragon > make a massive Enderman farm out in the void area (to avoid having to light up the main End island). Best exp source if you use a good trap design. Would be a good use of all your iron/redstone :)
I think Docm77 has a tutorial on one, his is pretty efficient. Etho also has an awesome design, no tutorial though :(
Meh, it'll be gone pretty quick.
Not with water, they'll teleport as soon as it hits them. Push them off with pistons.
Oh true... So like they get pushed off?
then hrrm. Alright. But then how would I get a big surface area for them to spawn and get pushed off of? I mean, if i went with the typical huge square, it would be hard to push them off if they spawned in the center
Etho used a design where they were instantly pushed off when they spawned, cause they spawned on a pressure plate. They would take fall damage to 1/2 a heart.
