Tutorials/Monster spawner traps

Monster spawner traps differ from regular traps, in where monster spawner traps use the mob spawners found in dungeons. The purpose of these traps is to create an infinite source of items from various mobs that can be gathered in an efficient way. Two general rules for these traps are to keep the mobs and the player separate and to allow the mobs to spawn. If you have created one of these kinds of traps, you may put it on this page. Note that you may want to change the difficulty to "Peaceful" for no worries of mobs coming up behind you while you build.

Drowning Traps
Drowning traps use water to drown hostile mobs (remember that mobs will always try to float, thus making them hit the ceiling and cannot go back down). The water currents also can be used to bring the items to you.

Drowning traps should make use of glass: it is impossible for mobs (including the player!) to float in water near glass; most possibly because of the "downward" flow of water next to glass.

Zombie/Skeleton Drowning trap
This trap is very simple to make and very effective. The zombie/skeleton will fall into a "drowning area" and the items dropped will collect in a central point. To start the construction first dig three layers down in the dungeon. Next one layer up from the bottom dig a slot all along the back of the trap. then on the opposite side dig three layers down and one block back from that dig one layer down. Now to start the collection room make sure the trap is five blocks wide. this will ensure that there can be a central collection point. Then dig a room five wide by seven long by three tall. Next (optional but useful) put a large chest and an infinite spring of water in the back of the room. Next put a glass floor above the spawner to make a place to walk and to stop mobs from spawning on the floor. Then build a stairway from the room to the floor above the spawner. Then put a glass wall the next block space from the three deep layer. Leave a space filled with a ladder for a temporary access point. Then put water in the slots at the back of the trap. Then put water above the 3 deep spaces. Then put a five by five square in the bottom room. This will keep the water from flooding the room. Then put water in the four corners of the box. then remove all torches (if any) and fill in the gap in the glass. Then the trap is done. Now you can get unlimited items.

Burning Traps
Burning traps implement lava or fire to burn the mobs to death. Depending on what you use, you must be careful designing your trap because fire and lava will destroy your loot on contact.

Cactus Traps
These are the most cost and time effective traps. First, make water flowing to one side of the dungeon. Next, make a hole on that side big enough to house a few, fully-grown cacti. Make sure to make the cacti one block off the ground to lessen the chase of destroyed drops (again, remember that mobs will always try to float, thus making them "jump" into the cactus instead of floating into it).

Spider Cactus Trap
This trap works very well on spiders and is very easy to make. First dig two layers down in the spawner room. Then choose an end that is five blocks wide and dig down four blocks. Then dig out a five wide by seven long by three high room. After that take away two blocks on the side one block away from the hole above the room. Then put blocks to make a five by five hole. Then put two cacti one block above the leveled out layer at the spawner by putting a block to support the sand. Make sure that the cacti are each one block away from the wall. Then on the oppisite wall put water source blocks all along the back wall. Then put a glass layer above the spawner. This will make sure that spiders can't spawn anywhere but in the trap. Then (optnial) put some glass above the cacti to ensure that the spiders stay at the cacti once there. Then in the bottom room put water source blocks in the holes you dug earlier and in the back corners to make a central collection piont. Then dig stairs up all the way to the glass roof above the spawner. Now your trap is done.

Simple Cactus Trap
Also known as a checkerboard trap, this trap involves removing blocks and replacing them with sand in a way that the floor looks like a checkerboard. Then, you place cacti on the sand blocks. Now, whenever mobs spawn, they will constantly be damaged by the cacti.

Other
Traps that use unusual methods that aren't used that often, such as huge pits, fall into this category.
 * Pit Trap
 * For this method, you must dig a pit that reaches far under the dungeon. Depending on the height, the mob will die on impact, as long as there isn't 2+ meters of water at the bottom. However, this method takes a long time to make and only works for spawners near or above the surface.


 * Sunlight Trap
 * The sunlight trap is like the pit trap, only in the opposite direction. You dig straight up around the spawner block until you reach the surface to let sunlight in. This will only work with zombie and skeleton spawners, because they burn in sunlight. This trap is easiest to make if the dungeon is close to the surface.
