Leviathan

A Leviathan has a chance to be summoned when you buy an offering at an Offering Well, with it's chances increasing with the more expensive offering you buy. The game should only spawn Leviathan on the map at once, however, there have been occurrences where more than 1 Leviathan spawned on the map at the same time. They can drop exclusive items you cannot get anywhere else, and are a late game powerful Enemy.

Finding Leviathans
Finding a Leviathan is difficult and requires persistence as they are quite rare. There are only two ways of finding a Leviathan, either you get lucky and summon one yourself from the Offering Well or you find it on the map.

When you get close enough to a Leviathan a rectangle with a yellow outline will appear on the top of your screen showing how much time is left until the Leviathan runs away. As you get closer you will eventually see the map marker appear, from there it is as simple as looking at your map.

Strategies
Often when a Leviathan spawns many powerful players will rush over to help attack it, it can take several minutes to put down a Leviathan as they are the hardest enemy currently in the game.

The Leviathan is unique in the fact it has multiple types, each part can have it's own individual type (Aqua, Lava, Spark, and Neutral which is green and exclusive to Leviathans) depending on the color it has, parts colors can change so look out for this if you have mainly only one Drone type. To defeat the Leviathan you have to remove all of the pieces around the Core, and then that leaves it open to attack, similar to a Mine.

Outer pieces such as engines, crab claws, etc. will be one of the three elements, and destroying them will make the neutral piece they are attached to assume a random element. This makes it easier to destroy it as the correct Drone type will have the boost to attack with.

Another incredibly easy way to tell what Drone is strong against what is just hovering over the Enemy, a Drone icon at the bottom of your screen with start flashing, indicating that is the one that is strongest against that type. This is incredibly useful against Leviathans as it can be hard telling which part is what element.

Rewards
The Leviathan will drop a Leviathan Core when defeated. The loot rewarded is based of how much damage you did to the Leviathan, other players damage does not increase your reward. This means it's better to systematically but of every piece instead of going straight for pieces around the core. However, going for pieces closer to the core usually takes more time, than destroying a part close to the edges of the Leviathan.

When a Leviathan Core is excavated it will trigger a menu to pop up which is very similar to a Supply Drop, 1-4 (depending on how much damage you did to the Leviathan), cards will be revealed and they can contain exclusive Parts along with other loot. It is recommended to try and do as much damage to the Leviathan as possible (So no taking shortcuts and just destroying the parts around the core immediately) as it directly effects the loot you get.

Additionally the Core also drops lots of Crystals and possibly some Gems onto the ground, much like a Mine or Shipwreck. It is often seen that the Leviathan Core often drops crystal cayouts of Massives and Legendarys.

If you do not see a Leviathan Core when they are defeated you most likely have the Leviathans Curse Glitch.
