Minecraft Golems can help you attack and defend against enemies. There are two types: Snow Golems and Iron Golems.

Step 1: Tether and Lead

Golems tend to just wander around. To keep them nearby you can either lead them around with a lead, tether them to a post with a lead or even block them in with a fence.

* Be careful about putting them next to each other as the Iron Golem can hit anything nearby and will kill your Snow Golems with 1 hit. It is better to keep them away from each other.

Crafting

4 Snowballs = 1 Block of Snow
9 Iron Ingots = 1 Iron Block

Will drop a few Snowballs when destroyed
Leaves a trail of snow wherever it walks which can then be harvested for more snowballs
