Tutorials/Snow golems

Uses
The main use of a snow golem defense turret is to keep enemies away from your house, they can also be deployed near NPC Villages to protect NPC villagers from hostile mobs and break up sieges.

There are two main types of Snow Golem turrets. Pushing snow golems use the sheer knockback from their snowballs to keep mobs away, while pulling snow golems use the fact that they attrack mobs to lure them into a hazard such as lava, cactus, or a pit.

Pushing Turrets
Pushing turrets require a large number of snow golems, at least three, preferably more. The sheer number of snowballs will push mobs away faster than they can reach the golems. This makes them very effective against zombies, and fairly effective against spiders if you have enough golems.

How to Build a pulling turret.
1.Dig a 3x3x3 hole into the ground.

2.From the center of the hole build up 5 blocks of a non-flammable material such as Cobblestone.

3.Surround the top block of the tower with non-flammable material so that there is a 3x3 square with one open block between the square and the hole.

4.Build another 3x3 square directly atop the last but without a center block.

5.On one of the non corner blocks build up 2 blocks, place a slab on all other non-corner blocks.

6.Build a snow golem in the middle.

7.On the 2 block tower from the top block place 1 block in so that it is above the golem's head and the golem cannot jump.

8.Delete the slabs and 2 block tower but leave the middle block floating, if you like you can make it a 3x3 square above the golem, however this is not necessary because after Beta 1.8 (The adventure update) Skeletons no longer fire in an arc, rather a straight line.

9.Delete the first 3x3 square (the one 1 block above the hole) without deleting the middle (the snow golem is standing on that!)

10.Delete the bottom 4 blocks of the tower but not the one your golem is standing on.

11.Place 1 lava on the bottom of the block the golem is on. Since the golem deals no damage (except to Blaze) and mobs will attack it if hit when they come up to it there is a chance they will die in the lava.

12.If you wish to make it more deadly you can place Cacti at the corners.

13. If you'd like to collect the drops, in the 3x3 hole, make the deepest layer have water on one side leading to a collection center, the middle layer signs, and the top layer lava.
