The **Esserwyrm** (Japanese: エッサーワーム *Essāwāmu*) is an Epilogue Superboss that drops Esseric Scales and various abysscent weapons.

## Spawn

The Esserwyrm spawns randomly in the upper layer of Sky Abyss near 8x8 squares made of Esseric Ore. When it spawns, it will orbit the square, then ram into its nearest target.

## Behavior

The Esserwyrm doesn't attack the player if player doesn't attack the Esserwyrm, and summons will not attack the Esserwyrm if not commanded by tagging. It will instead attack nearby Lacelineous creatures.

When spawning, It will do 2 circles around the square to spawn all the segments, then it will slow down, stay for 5 seconds and rapidly ram into its nearest target, then it'll slow down again, and ram near its next target, circle around it, and ram into closest 6x6 block space, and wait for 10 seconds, It will repeat the process until it gets attacked by the player. If the player attacks the Esserwyrm in the middle of a cycle, it will finish the cycle, but with the player as a possible target

After the cycle restarts and it was attacked by the player, a Boss Health Bar appears on the interface, and the actual fight begins.
The Esserwyrm tries to kill the player using the following attacks:

* Slowly chases the player shooting fire that inflicts the Evercold debuff
* Circles around the player making the circle smaller
* Dashes into the player 3 times, Generating *Scalar Stone* on his way, *Scalar Stone* is a solid block that requires 200% pickaxe power to mine, the block does not drop when broken. (Revengeance Mode only)

After the boss reaches half of its Healths, it starts growing in size and after 3 seconds it activates its 2nd phase. In this phase the boss becomes insanely fast, the following attacks can appear:

* Circles around the player creating scalar stone
* Goes to random edges of the Screen creating evercold fireballs that slowly home onto the player
* stays at one place for 5 seconds and then dashes at the player dealing massive amounts of damage (Revengeance Mode only)

The boss can heal itself by destroying other creatures:

First Phase:

* Abyss Enemies +100 / **200** health.
* Lower Sky Abyss Enemies +300 / **500** health.
* Weaverbug +375 / **750** health.
* Skyline shark +1500 / **3000** health.
* Player +10000 / **20000** heath

Second Phase:

* Any enemy with less than 10000 hp + 5000 / **10000**
* Any enemy with 10000-99999 hp + 25000 / **50000**
* Any enemy with 100000-999999 hp + 75000 / **150000**
* Any player + 100000 / **200000**

## Tips

Because the Esserwyrm doesn't lower enemy spawn rates, it is recommended to use Zen Potions and/or Tranquility Candles to lower spawn rates, so that it heals less.

## Trivia

* The Esserwyrm is considered a **"Superboss"** in this mod. In some RPG games, Superbosses are extremely powerful enemies that are very challenging even if the player has endgame equipment.
	+ It shares this trait with the following bosses: Adult Eidolon Wyrm, Vision of the Tyrant, The Entropic God, Noxus, Disgusting Creature: Dron, Reactive Guardian, Sodis, Nihil, the Fathomless Seeker and Exodygen.
* If the Boss Checklist Mod is installed, its unique despawn message will be "The Esseric Lord disappears into the deep blue skies."
