Terraria has many challenging bosses to defeat, each with its own characteristics and ways to summon. In this list, we focus only on the mandatory bosses to beat to progress through the game, both on Normal and Hard modes. We include the ones from the PC, Android, and iOS versions, and we inform you about the attributes of each boss, how to summon them, and the drops they leave when they are defeated.
Note: quite a few figures are presented as 2,000/2,800 or 15/30. In these cases, the second number corresponds to the Terraria Expert mode.

As he takes damage, he gets smaller and more agile, as well as summoning little blue Slimes that will make combat more difficult. Avoid getting trapped in a closed space, don't let him corner you!

After taking an amount of damage, the Eye will transform. As soon as that happens, attack him as many times as you can until he charges. He will do three lunges in a row. Dodge and make sure to attack again at the end of his third charge.

The attacks with the hands are somewhat irregular, so pay attention to their movements. From time to time, the skull will begin to rotate.

From then on, Plantera will be faster, do more damage, and have a higher defense. Your best option is to use long-range weapons to continue doing damage. This way you will have more time to dodge its seeds, flowers, and tentacles.

In the second phase, Golem will start shooting lasers at you faster and faster the less health it has. If you take all of his life, he will reveal his final form. The goal in the last phase is to attack his body. The surprise is that Golem can go through walls and will be a much more ferocious enemy than at the beginning.

How to Summon: After defeating the Golem, go to the dungeon and find four cultists praising a mysterious tablet. defeat them
Don't be fooled. The Lunatic Cultist looks weak, but his attacks are strong. At first, he becomes invincible for a few seconds and teleports several times. He has a fixed pattern of attacks, which is to throw 3 fireballs, an ice ball, and create an electrical orb. Try to attack during this pattern and before he teleports.
After taking an amount of damage, the Lunatic Cultist adds the fourth attack: 2 groups of 5 light projectiles. After using this attack 5 times, he will create two clones of himself. If you damage the clones, the boss will summon a Ghost Dragon or Ancient Vision if there is already a dragon in play. As you can see, it's a rather complex boss!

1 Gold Coin, Lunatic Cultist Mask, Lunatic Cultist Trophy, Major Healing Potions, and Ancient Manipulator.
lord of the moon

Defense: 50 head, 40 hands, and 70 core.
Immune to: Confusion.
How to Summon: After defeating the Lunatic Cultist, the Lunar Event will start, spawning four columns (Solar Column, Nebula Column, Vortex Column, and Stardust Column). They are spread over different parts of the world. You must defeat 100 enemy guardians (150 in Expert mode) and then destroy the corresponding column. By destroying all four columns, the Moon Lord will appear. If you've already completed the event, you can summon it with a Celestial Seal.
This is the last boss in Terraria and therefore also the most difficult. He is the one with the most hit points in the game and the most damaging attacks. The trick with the Moon Lord is that in order to defeat him, you must first destroy the eyes on his hands and head. It's the only way to hurt him!
The eye on the head fires laser beams, while those on the hands alternate between different types of projectiles. When you defeat one of the eyes, it will detach and become a True Eye of Cthulhu, which deals damage on contact and attacks similar to the eyes of the hands. Instead, the holes left on the hands or head will become thorny. These also do damage on contact!
To top it off, the Moon Lord can also summon a tongue that, when touched, will prevent you from healing. Not only that, but Leeches will be summoned on contact and if you don't kill them before they reach the boss, the Moon Lord will be healed for 1,000 health.
