Golem

The Golem is a Hardmode boss. It is summoned by using a Lihzahrd Power Cell on the Lihzahrd Altar, which is found in the Lihzahrd.

Like many other bosses, the Golem has two stages. In its first stage, the Golem will shoot fireballs, extend its fists, and occasionally jump around. When the head reaches below half health, Golem will begin to shoot lasers.

Its second stage activates when it´s head has been "killed". Once this stage activates, the Golem's head will detach and fly around above its body, taking no damage and firing lasers at the player whilst they continue their fight with the body. In addition, its movement will speed up.

Tips

 * You can place platforms in the room vertical wise and the Golem will spawn ontop of the platforms making him easier to dodge and attack from below.
 * Megashark or Stynger ranged weapons can easily destroy this boss in record times. Though you can only get the Stynger from the Golem itself.
 * At low health The Golem will be firing lasers faster and faster so try and save your health and potion use for that part.
 * If you manage to get a Piranha Gun, it is very easy to slowly take out the Golem by hiding after shooting.
 * Using the Bunny Cannon and a wall between you and the Golem, you can very easily take this boss out in a short amount of time. Takes about 50 bunnies, just spam-click the cannon until it dies (tip: aim the cannon straight up and wait for the boss to stand on top of it).

Trivia
The Golem might be a reference to Kaos Karnage from Donkey Kong Country 3: Dixie Kong's Double Trouble

This is commonly thought of as a hard boss, despite becoming very easy with the right preparation.
