Raid

A Raid (not to be confused with Pillager Raids) is a server event where a location is selected with an event. The first Raid to be introduced was Etheria, which was mainly successful serverwide.

Etheria Raid
Etheria was the first raid to happen on EarthCraft. It was on Earth in the middle of Europe, and was a course where you fight multiple entities, with the last being the Etheria Golem.

Moon Raid
The Moon Raid was the second raid on the first Earth. It was located on the moon in the Etherian Arena, fighting a boss wave and the Etheria Golem, this time with two phases. The first phase has the Golem do ordinary attacks, while the second phase gives him more health, speed, attack, and allows him to shoot lightning. The Golem was defeated.

Final Raid (Ragnarok)
The Final Raid was the last raid to happen. It was located in the Etheria Outpost in North Africa, fighting the entire Etherian Army along with the Ether. The Ether was similar to the Etherian Golem, except this time it was a zombie-like creature with full netherite. It could shoot lightning, run faster, and plow through players easily. The second phase of the Ether not only amplified his powers like the Golem, but also gave it the ability to shoot Wither heads. The final boss of this raid was the Ether Giant, the final evolution of the Ether, taking place inside the massive Etheria Cube. All the players transformed into their True form (being forced to) and battled the Ether Giant while flying around. The Ether Giant was able to shoot lightning and wither heads that could instantly kill any normal player, however True forms were invulnerable to this. The Giant was defeated and the world later plunged into a reset.
