1 - Introduction.
Hello ladies and gentlemen! After sifting through a ton of guides on killing Gaia III, I was a bit disappointed since I couldn't find anything good. They mainly talk about what gear to wear and that's it. So, what's next? You go in fully confident that you can kill her and then you die. Then people ask how to kill her? In this guide, I decided to share my experience fighting this boss. The guide is mainly aimed at beginners! Well, I think we can now start the description.
2 - Killing Gaia Level I.
If you want to kill Gaia Level I, what do you need? First, we need to build a structure that is suitable for fighting all Gaias. For this structure, we need a free space of blocks. Any blocks can be used.

To summon, we need 1 Terrastal (how to make it is written in the Lexicon). Now before summoning, let's talk about the equipment we need for the damn Gaia! The simplest thing you can do is to enable /god and not worry. But if you're not of noble blood, you will need diamond armor with Protection IV enchantment, a diamond sword with Sharpness V, and golden apples (can also be made from ingots). Our inventory looks something like this.

Once everything is ready, we can bravely go into this great battle with the black one. It has 320 HP and relative damage. If you hit the boss with two people, it will have 320 HP more, but the damage remains unchanged! It also occasionally summons bats, which, when they hit you, inflict the Withering effect as well as instant damage. The method of killing is simple: run around in circles and be Neo, although you don't necessarily have to be him. When it has a little HP left, it enters phase two. A clone rises, becomes immortal, and spawns vanilla monsters. In general, you can ignore them, but then there will be a whole army of them and they will suffocate you. Hooray, we killed Gaia and received 6-8 Gaia spirits. Not much, but it will do for the first time.

If two people had fought the boss, there would have been 4 more Gaia spirits and so on for each player.
3 - Killing Gaia Level II.
Gaia II is similar to I; it still has 320 HP, but it hits harder. The structure is the same as for Gaia I. It is summoned with a different item, Spirit Gaia Ingot.

You don't even need to change the equipment.

In simpler terms, do everything the same as in the fight with Gaia I.
Now let's talk about the loot that drops from it. What we can get is shown in the screenshot.

There's nothing more to say here, so let's move on to Gaia III.
4 - Killing Gaia Level III.
Here is where everyone starts having problems with killing Gaia Level III, and many people do not understand how to kill her and simply die. I will try to explain an easy way to kill her.
Not only does she hit hard, but she can only be damaged by vanilla, botania, and extra botania items, and others are just thrown on the ground or do not allow you to summon. First, we need to prepare an arena, as well as become a royal maid. Let's start with the arena; overall, it is the same as before, but here we will add a nano bots station (Level 3 is sufficient) for regeneration, strength, increased health, and resistance, which we need for buffs to make killing easier, and 4 spinel spikes (4 is essential) that help us ignore the heads that appear during the boss battle. All this should look like this.


If you do not have a nano bot mod, then golden apples, a divine strength potion, and a turtle shell can serve as an alternative, it will be harder, but still. We just need to get a lot of useful buffs for the battle and go to fight. You can even receive buffs in advance. One thing to understand is - death is going to happen in any case! =(
Now it is time for our equipment. We should wear the battle maid outfit (there's nothing better), Odin's Ring (for HP), Super Crown (suitable for a maid, takes half damage from herself), Mana Driver Ring (to power spinel spikes, but can also be through a pool or mirror), Terra Blade (there's no better sword in this battle), Cloak of Sin (once every 10 seconds inflicts the same damage on the enemy that was dealt to you), and Terra Defender (or any good accessory that can be put in the Bubble quest).

Everything is prepared, and now we can start the grand battle of all time. It is summoned by the Nature Sphere or a ticket for summoning, which drops with a small chance from Gaia II. If you are too lazy to make a sword, you can hit with your hand because due to the maid outfit, we can deal much more damage than without the outfit. I prefer to hit with a sword since it's more convenient for me. After summoning, we approach her, hit immediately, and do this until the end. As soon as the heads appear, you are immediately pulled to the beacon and swords appear from above - that’s the boss's ultimate, the most fearsome thing. Spinel spikes take care of the heads, and we are not afraid of anything except for the pulling for some time. Mines frequently appear, and if you are near them, your HP will noticeably decrease over time. To avoid damage from them, you need to run to where they aren't. And we continue until 0 HP. From her, we get Pandora's Box, more details in the screenshot.

5 - Killing Gaia Level IV.
Gaia Level IV is named Ruler of the Void. She has 300 HP, all the abilities of Gaia III, and new ones, as well as several phases in which, not only is she immortal for a short time, but she also fully heals. I forgot to mention that she copies all effects that you have. To make it easier, you should not eat golden apples and also disable the nano station. It may seem that she should be difficult, but in reality, she is even easier than Gaia III, and I will explain why.
Let's prepare for the battle with the lady. As for the equipment, it's the same, but we add The Oath of Judas KIRA. This oath makes the fight with the boss so simple that Excalibur might as well not be made.
She is summoned with the Call of the Void. 
Now the lady appears and immediately starts hitting you, but you are no fool and spam The Oath of Judas until the end of the fight. There’s nothing difficult about this battle, and we rightfully receive the reward. The loot is the same as from Gaia III, just with added decor items and a limited bag, and from it a super lens.

6 - Conclusion.
I will conclude here; I have tried to share everything I know. I hope it has become much easier for you to kill Gaia III and IV. In closing, I can only share my Discord in case any questions arise. TTon4ick#4859
