Hi, me and a few friends play on a survival server one of them owns, and I live with a guy in his mansion, but he stole some of my stuff laughing about it, after he killed me. Anyway, i need to make a secret base under his mansion >, but can't find any slimes for sticky pistons(believe me I've tried) or spawn slime-balls in D: . So what are your ideas for a secret base to hide my diamonds while i plot against him?

EDIT: i don't want to blow him up just yet, i'm going to remove his nether portal so he's trapped instead

ANyone? I need help quickly while he's not on

Why are you even living with a guy who laughs and steals your things, after he kills you?..

Just make a mine somewhere near and go underneath his house. BTW, get a lot of TNT, place it under his house, take all your stuff and run out while setting the TNT off..

he's one of my mates, i thought it was a laugh and i just want revenge I stole loads of his iron aswell, so it's all fair

Oh ok. Now I understand.
How about some kind of trap where he falls into a cave?

Or, random tnt. He might not trust it

No, he'll just respawn and kill me some other time, i just want a secret place for a while before i blow him, house, and portal(while he's in it) up

Does he have any secret rooms, or any rooms not used?

Also, that unlucky moment when he finds this thread.

Just found more diamond(I don't think he has any ;P) and made a small lava trap to piss him off for a while
