How do you protect your base from walker swords?

[werbth]

I play on a hexxit pvp factions server but people keep getting in my base with walker sword. Is there any way to stop that from happening? Maybe a block that walker sword can't teleport through?

sorry dude, but walker swords can teleport through anything. try building your base so far under people can't detect it, and maybe even som traps where a walker sword teleporter would fall through the bedrock and die
