Hey guys this one is for you guys and girls for helping me level up! 

Five ways to defend your territory in Minecraft-
One- Landmines. Dig two blocks down amd place a tnt, then place your soil block, put a pressure plate on it, so when a monster steps on it, BOOM!

Two- Tripwires. I'm sure you guys know hoe those work

Three- Mob death rooms (for players). A single block down to a room full of monsters, place in a concealed spot.

Four- Gravel/Sand traps. Have pistons on walls connected to pressure plates and make them move so gravel or sand ababove it crushes player or mob.

Five- Spider lava trap. Have three blocks in the ground have lava in bottom and webs in top two, so they slowly sink to their deaths.

Thanks guys, I know it was short but I hoped it helped you defend. If you want to please diamond and subscribe!
