Iron golems are large, strong
utility mobs that defend
villagers.
Creation
Iron golems spawn naturally in
villages (natural or player-made), provided there are 10
villagers and at least 21 houses (counted as doors). The chance of spawning is 1 in 7000 per
tick, which averages around one every six minutes.
The golem also can be built using blocks in a similar fashion to
snow golems and
Withers. To do so, the player must place 4
blocks of iron in a T-shape, and place a
pumpkin or
jack o'lantern[upcoming]
on top row in the center slot. The pumpkin must be placed last by the
player. Players should not manufacture iron golems next to a wall
because they may suffocate and die.
Behavior
Iron golems will wander around a village in a patrol-like fashion,
staying close to the edges of buildings and such. If not within a
village, iron golems will slowly wander aimlessly, attacking any hostile
or neutral mob within 16 blocks of them (not including
wolves). Iron golems are completely resistant to
drowning and
fall damage, making them good tools for both
villager
protection and personal use. While resistant to drowning, they will
sink in water and become immobile, and will not attack anything.
Iron golems can walk up a full block height without jumping and walk
over a 1 block wide hole without falling in. They will avoid water and
lava at all times; however they make no attempt to avoid fire or cacti.

Like villagers, iron golems will not wander away from a village,
regardless of how they were spawned. Iron golems will sometimes face a
villager, as if they are speaking to each other. Iron golems are able to
hold poppies and give them to villagers, symbolizing the friendly
relationship between the villagers and golems. However, they won't give
poppies to other iron golems.
Attack
Naturally spawned iron golems will attack the player if the player
attacks them first, but will give up if the player moves out of their
search radius. The iron golem will also attack the player if they attack
a nearby villager. Other mobs can also initiate the same mentioned
behaviors. The iron golem does not have to directly see the player/mob
attacking a villager to become hostile.
Any iron golems built by the player will never attack players under
any circumstances, but will still protect villagers from zombies. Iron
golems will never attack
ghasts and will only attack a
creeper if it happens to cross its path.
When provoked, an iron golem will move quickly toward its target and
once in range will swing their arms up violently to attack, dealing
7 (
) to
21 ( × 10.5) damage and flinging the target into the air. This attack is the 2nd strongest attack in the game, beaten only by a creeper's
explosion.
Iron golems have a comparatively large attack range, allowing them to
attack through a solid 1 block thick wall, even without line of sight to
the target.
Drops
Iron golems drop 3-5
iron ingots and 0-2 poppies upon death.
Uses
Defense
An iron golem's primary purpose is to defend villages from
zombie
attacks. Although slow, their high health and attack strength prove
them to be great defenders. They swing their arms during their attacks,
causing enemies to be thrown into the air and usually killed in one or
two attacks. Player usage might involve enclosing golems in a large
fenced-off area to prevent their wandering off, although such control of
the area could be accomplished in simpler ways.
Although iron golems are very strong mobs, they require a good deal of
iron to build, and are prone to wandering off or being distracted by nearby monsters.
Zombies, skeletons, creepers (before 1.8.1-pre1),
spiders,
cave spiders,
slimes, and
magma cubes
will naturally attack iron golems, possibly causing it major damage
especially in groups. Additionally, the golems may attack nearby
creepers,
endermen,
zombie pigmen, spider jockeys and
witches,
which can also severely damage them. Players are encouraged to help
iron golems in these situations to ensure their survival. Iron golems,
like passive mobs, can be leashed.
Spawning
Golems will spawn in a 16x16x6 area, centered between the 21 or more
valid doors in a village if it has at least 10 villagers. Additional
houses beyond the 21st will make no difference as far as golem spawning
is concerned, but you will need 29 of them, at least initially, in order
to spawn ten villagers naturally (after that you can cut them back down
to 21 if you want to). However, having additional villagers beyond the
tenth will allow more golems to spawn, in increments of one golem for
every ten villagers (so 0-9 villagers allows no golems to spawn, the cap
is set at zero; 10-19 raises that cap to one, 20-29 raises it to two,
etc.). This cap only limits the number of golems in a village at any one
time; as soon as one is killed or leaves the village boundaries, a new
one can spawn in its place immediately.
As long as all the conditions are met (10 villagers, 21 houses, golem
cap not reached), then each game tick (1/20 of a second) there is a
1/7000 chance the game will try to spawn a golem. A random spot is
chosen inside the spawning zone, and if that spot contains a solid block
with at least 2×2×4 space above it (including liquids, which is key to
the iron farm designs linked below), then a Golem is spawned there.
This is repeated up to ten times or until a golem is spawned,
whichever comes first. Then, the check is repeated each game tick, until
enough golems have been spawned to reach the cap, at which point
spawning is put on hold until either a golem is eliminated or the cap is
raised. This means that the average expected spawning rate (for an iron
farm, for example), if the golems are killed or flushed outside the
village boundary quickly enough so that the cap is never reached and new
ones are able to spawn in their place immediately, is roughly 10 golems
(30-50 ingots if you're farming them) per hour.
Farming

An iron golem farm is an artificial village (or several of them,
spaced far enough apart to remain separate) in which golems are spawned
and then either killed immediately, or moved to a holding cell (outside
the village boundary, so that new ones can spawn in their place) for
later killing. A holding cell housing the golems can be created to allow
the player to easily farm the golems after the player has remained
inactive at the farm. Alternatively, resources can be collected using
hoppers after they have died from suffocation or lava.
Killing
There are several ways to kill iron golems and obtain their drops. The following are the most effective ones:
- Suffocation by a sticky piston and a block. The killing can start
instantly after spawning but it will clog up the trap, making other
golems unable to either spawn or die, depending on the design.
- By lava that won't touch the golem's feet (since this is where the
drops appear). This is the most damaging (and therefore quickest) of the
automated killing methods. An example picture of this method is shown
to the right.
Note: Falling and drowning traps are ineffective as iron golems don't take fall or drowning damage.
If the iron golems are dropped at least seven blocks below the floor
block(s) of the house, they will immediately be outside the village
boundaries, and therefore detached from the village, so a new golem will
be able to spawn, even before the previously village-attached golems
have died.
If there is no other spawn space available, iron golems will be able
to spawn inside liquids, meaning an instant lava killing trap is
possible, as shown on the picture to the right. Dropping the iron golems
out of the spawn boundaries as soon they spawn, however, could be seen
as preferable to this method, as it ensures a higher iron golem spawn
rate.
The traps could have a collection area, where the player can pick up
the drop items. It is possible to have multiple golems spawn in one area
to make a very effective farm.
If a player is short on resources and time but still wants to harvest
the iron from golems, they may simply suffocate the golems with sand or
gravel. Golems are very slow-moving and tend to wait at the same spot
when not patrolling a village, so it is very easy to drop three blocks
of sand or gravel on top of them and wait for suffocation.

enough protection and enough pearls, one could travel a long distance
very quickly. Ender Pearls do not function in creative mode.
