Ya just have to have a friend ready and waiting, and that idea is pretty much fool proof if you fire down splash potions on a 1 redstone tick clocked circuit.

Actually, you could make it automatic extremely easily by just pushing a button and logging off. No need for a friend/alt. :D

Hey, a pitfall trap (completely underground lined with walls) with zombies at the bottom would be nearly impossible to escape... plus you'd get all of their equipment.
You'd just have to make sure the ground is completely covered in zombies (easy with a small surface area) and they can't place anything on nearby walls like water/lava buckets which you can do by making the walls at the bottom stretch back a ways.

They can't place anything on walls to help, they can't place anything on the ground (easily) to help, they would die from impact immediately (and if they teleport, they can only teleport up high on a wall, resulting in falling again, or they land on the ground covered in zombies)

@ViciousKangaroo it looks more like your minecart tnt ignited a cluster of hidden tnt below it lol...

Just looked it up and had no idea but (from the wiki)
"The faster the minecart, the more powerful the explosion."

This gives me so many ideas...

I don't think anyone (who has any brains) will be trying to trap you anytime soon lol

Most people accept tpas with a weapon in hand and generally don't have epearls prepared... maybe jumping off the tower and accepting would be a good plan.

How well does a pitfall trap work? Like you back yourself into a corner ledge of only one block, get them to tp, then knock them off the ledge?

Do players tp to your exact character position or the nearest rounded block position?

Posting a selfie here is never regrettable. :P

Ah yes. I remember now from your previous posts. Apologies

He found the base, he can level it to the ground if he wants lol

Lol snowburn didn't last but a week
