Golem

“The stone-faced ritualistic idol of the lihzahrdian tribe...”

Golem is a Hardmode, post-Plantera boss found in the Jungle Temple. It can only be fought after Plantera has been defeated in the current world.

In its first form, Golem has three target areas: its head and its two fists. After its head is defeated, the head flies off and the body becomes the target while the invincible head attempts to defend the body.

While Golem is alive, music Boss 5 will play.

Summoning
Golem is summoned by using the key on the Lihzahrd Altar, located in the final Jungle Temple chamber, while at least one Lihzahrd Power Cell is in the player's inventory. One Lihzahrd Power Cell is contained within each of the Jungle Temple's Lihzahrd Chests, and can be dropped rarely by Lihzahrds or Flying Snakes (2% chance). Golem spawns directly above the Altar. Plantera must have already been defeated at least once in the current world in order for Golem to spawn successfully. If it was not, the summon will fail, and a Lihzahrd Power Cell will not be consumed from the player's inventory.

Behavior
Golem's main body cannot move through blocks. The lasers it shoots, the fists, and the invincible head during second phase pass through blocks.

First form
Golem shoots ricocheting fireballs, attacks with its fists that extend from chains, and jumps around. These increase in frequency as each part takes more damage: When the fists are damaged, they attack more often; when the head is damaged, Golem shoots more often. Golem's fists can travel through blocks, but have limited range, and will also retract immediately upon being hit with any weapon. Golem jumps around more often when a fist is destroyed. This compounds when both fists are destroyed.

When the head falls below half health (8000), all previous attacks continue, but the eyes will begin to fire eye lasers that can travel through blocks. It fires more rapidly as it takes more damage, and the fists do not retract when hit with a weapon. His head turns, which indicates who he's targeting.

Second form
When Golem's stone head has taken full damage, it detaches to reveal its core. Its body (9000 / health) then becomes the target. If the fists have not been destroyed, they will continue to attack the player more rapidly while the body continues to jump around.

The detached stone head is invincible, and can't be hit. It flies around and can move through blocks, fires lasers that also travel through blocks, and shoot ricocheting fireballs. Both the fireballs and lasers are fired more frequently as the body takes more damage.

Once the body drops to 0 health, Golem will explode and is defeated.

Aftermath
Once Golem is defeated:
 * Cultists spawn at the Dungeon's entrance, which can be used to summon the Lunatic Cultist and then the Lunar Events (provided that Skeletron is defeated as well).
 * Martian Probes begin spawning randomly, which can trigger the Martian Madness event.
 * Summoning the Old One's Army after Golem has been defeated triggers the most difficult "Tier 3" version of the event.
 * The Steampunker will begin to sell the Steampunk Wings. (Verify)

Tips

 * By using actuators players can "increase" the Jungle Temple arena space for more maneuverability.
 * If a player is lucky enough to obtain it with a single Golem fight, they can use the Picksaw to remove the Lihzahrd Altar and place it in a more suitable arena. On the, the player can also use actuators to remove the Lihzahrd Altar to move it into a suitable arena. ( It has been reported that this method will corrupt your world save files, rendering you unable to re-enter the world, so please do this method on worlds you do not wish to keep.)
 * Due to Golem's lack of mobility, it's possible to build a simple wooden platform or use a Grappling Hook above Golem and shoot down at it during its first phase.
 * Golem cannot move through solid blocks, so a player can create a cage of blocks to encase the Lihzahrd Altar (make sure it is big enough for the Golem to fit inside). Use weapons that can attack through blocks, mine gaps in the cage walls to fire through, or place trap mechanisms within it. Golem's eye-lasers and fist attacks will travel through solid blocks, but the cage will nullify its jumping mechanic (not only removing a large portion of the fighting movement, but also making him easier to hit, which speeds the fight up considerably).
 * Alternatively, a player could build a box to stay inside (or just a ceiling) a little bit above the altar, but below where Golem will spawn, then use a weapon that can go through blocks (such as the Clinger Staff). This will protect the player from Golem's jumping attack. The player can destroy Golem's fists to make the battle easier.
 * In some cases, the terrain surrounding the altar will cause Golem to get stuck when it spawns. It can attack with its fists and projectiles but will be unable to jump around. Players can also recreate this condition by placing blocks near the altar.
 * For magic users, Spectre armor with Hood combined with a Magnet Sphere or Razorpine can make the fight a matter of simply moving around. The damage from the weapons provides enough healing to counteract almost all attacks due to their high rate of fire. Using this strategy with the Vampire Knives allows a player to defeat the Golem without needing a single Healing Potion.
 * On the, using a Flamethrower, Fire Gauntlet, or similar weapon or accessory can be useful when fighting Golem, as Golem is not immune to On Fire! on this version. As of the 1.2.3 update the Golem now has immunity to the On Fire! This includes the Poisoned Debuff.
 * If you wish to battle Golem somewhere else, you can use Actuators and place them under the altar and connect wires to it and connect it to a switch or a lever. Use the switch/lever and then the Altar will drop for you to pick it up and place it anywhere you'd like it to be.
 * For melee users, Turtle armor minimum is recommended due to Golem's high damage attacks. The Vampire Knives can also help the player heal quickly should they have Potion Sickness.
 * Building a shelter against the fireballs and knocking the fists back should destroy both fists and lower the head’s health to at least below half.
 * If the head chases a player too far away, the body despawns and the head will explode. In this case, no drops will be obtained and does not count as a Golem defeat.

Trivia

 * A is a being from Jewish folklore, created from mud or clay and brought to life through rituals in order to defend townspeople from attacks. The theme persists in stories and video games today.
 * Golem is one of the four bosses with legs. The others are Lepus, Ocram and Lunatic Cultist.
