Jungle Dragon, Yharon

"The loyal guardian of the Tyrant King..."

Jungle Dragon, Yharon is a major post-Moon Lord boss fought in the Jungle. Yharon must be fought on two different occasions before he is fully defeated, with the second fight featuring a new and intense second phase. The player should be well equipped and prepared before summoning him as the boss is incredibly challenging.

Defeating Yharon for the first time will cause the Solar Eclipse event to be buffed, and all enemies in the event will begin dropping Darksun Fragments, a useful post-Moon Lord crafting material. Alongside this, Yharon's complete fight is unlocked.

Defeating Yharon the second time will provide the player with Yharon Soul Fragments and generate Auric Ore in the world, granting the player access to one of the highest tiers of equipment, as well as the Eye of Extinction, used to summon the superboss Supreme Calamitas.

Spawn
Yharon does not spawn on his own, and requires the player to summon him with a Dragon Egg in the Jungle.

Behavior
Yharon is incredibly fast and deadly, almost always charging the player at high speeds, dealing an extreme amount of contact damage. Between these charges, he will also perform a plethora of other deadly attacks, from firing a variety of projectiles, summoning many lingering Flarenadoes and Infernadoes, and spawning several minions to fight alongside him.

At the start of the fight, Yharon will summon two massive stationary Arena Infernadoes ( blocks to the left and right of the player (measured from their bottom-left corners) to serve as arena borders. Hence, the border Infernadoes will not be centered on the player's current position. Touching the Infernadoes will instantly kill the player. Successfully leaving the arena, or flying above Yharon's designated enrage height ( blocks high) will cause Yharon to become enraged, which massively increases his speed and quintuples his damage until the player returns.

Yharon's charging speed is adjusted based on his distance from the player, meaning that he is difficult to outrun and he can quickly approach the player from anywhere in the world.

Subphase 1

 * Charges twice consecutively.
 * Spawns Detonating Flames which fly towards the player, attempting to deal damage by ramming them or shooting, and a line of which start slow, but rapidly accelerate and home in on the player, however cannot turn very well.
 * Charges once, and does a fast charge, in which he goes twice as fast and far.
 * Yharon will remain stationary for a second and roar before he performs his fast charges. During this telegraph he gains 40% damage reduction.
 * Creates two projectiles, which fall to the ground diagonally away from him. Upon contact with a tile or after not hitting a tile for a second, a large Flarenado is spawned.
 * Upon reaching health, Yharon transitions to his second subphase.

Subphase 2

 * Charges twice, waits, and then once quickly.
 * Teleports above the player, and flies repeatedly in a circle, spawning Detonating Flames and shooting out in a bullet-hell style circle pattern, with random openings of various sizes.
 * Yharon does not deal contact damage during his bullet-hell style attacks and gains 40% damage reduction.
 * Waits for 3 seconds after the flare dust rings and then does 2 slow charges at the player.

 * Does one normal, then one fast charge.
 * Creates a homing Flare Tornado, which spawns a Flarenado upon impact.
 * Teleports near the player, and flies repeatedly in a circle, spawning Detonating Flames and shooting flare dusts out in a different bullet-hell style star-shaped pattern.

Intermission
Upon reducing Yharon's health to 10% or lower in phase 1, one of two things will happen depending on the player's current point progression.

The first time he is fought, and in any fight with him thereafter before gaining the dark sun's power, Yharon will fly away and end the fight there. All of his loot drops from the sky, except for the following:
 * Drew's Wings
 * His lore item
 * His trophy
 * Void Vortex
 * Yharim's Crystal
 * Yharon Soul Fragments

A status message appears in the chat directing the player to the newly-buffed Solar Eclipse.

Once the player returns to fight him again, the battle continues properly: Yharon now becomes invulnerable and regenerates 90% of his health, transitioning into his second phase. Yharon's damage reduction will increase from 24% to 26%.

 * Charges twice normally once more and then flies in a loop, doing the flare dust bullet hell and spawning Detonating Flames.
 * Upon reaching health, Yharon transitions to his fifth subphase.

Subphase 5

 * Similar to previous subphases with the new inclusion of teleports that occur right before a fast charge.

Aftermath
Once Yharon's first phase is defeated, the following things happen:

 * The Bandit will begin selling Dragon Scales.

When Yharon's second phase is defeated, the following things happen:
 * Auric Ore generates in the Cavern layer.
 * The Murasama can be used properly.
 * Scryllars begin dropping Gael's Greatsword.
 * The Sand, Cloud, and Brimstone Elementals from the Heart of the Elements now deal contact damage 20 times per second.
 * The tornadoes from the Sand Elemental now deal damage 20 times per second.
 * The Offensive and Defensive Guardians from the Profaned Soul Artifact now deal 300 damage.

Tips

 * Always be cautious when moving horizontally, as the arena infernado will instantly kill the player without warning.
 * It is advisable to put up solid blocks in front of the barrier infernadoes to prevent accidentally contacting them. Because the places of the infernadoes are measured from their bottom-left corners, the actual block to summon Yharon is not in the center of the arena. The arena should have a height of blocks and a width of  blocks. The block to summon Yharon needs to be the  block from the left wall. This will ensure the player never touches the infernadoes.
 * A good tactic to avoid Flarenadoes is to fly to the edge of the arena and let the Detonating Flames hit you, dealing no damage to you and forcing the Flarenado to spawn out of the way of the fight.
 * The Rod of Discord or Normality Relocator are great tools to use during the fight to avoid the flarenados and some of his attacks.

Trivia

 * Yharon's first phase theme, before unlocking the second phase, is Infernal Catharsis (Rebirth), which was composed by the artist DM DOKURO.
 * The in-game version starts a little further than the video, possibly to make it less similar to the original one.
 * If the Calamity Music add-on mod is disabled, Boss 1 will play instead.
 * Yharon's first phase theme, after unlocking the second phase, is Infernal Catharsis, an original version of the previous theme which was also composed by DM DOKURO.
 * This is the only theme that is not on DM DOKURO's official album. This is because when he made the "Rebirth" version, it was intended to replace the original one (which it did in an older version) even if the player unlocked the second phase.
 * If the Calamity Music add-on mod is disabled, Boss 3 will play instead.
 * Prior to the release of the original Infernal Catharsis, Yharon's theme was Kyurem's theme from the game Pokémon Super Mystery Dungeon.
 * Yharon's second phase theme is Roar of the Jungle Dragon, which was also composed by DM DOKURO.
 * This song contains full lyrics sung by DM DOKURO himself. The song is a warning from Yharon to his master, Yharim, about the strength and unstoppability of the player character. The song's lyrics are considered non-canonical to the mod's official lore.
 * If the Calamity Music add-on mod is disabled, the Moon Lord's theme will play instead.
 * Yharon's design took heavy inspiration from Falzar from the Mega Man Battle Network series.
 * Yharon was previously known as "Jungle Phoenix, Yharon".
 * Yharon used to have a 4th subphase in phase 1, however this was removed in update 1.4.5.001
 * Yharon can be fought before fighting any other post-Moon Lord bosses, as the Dragon Egg's recipe requires no post-Moon Lord materials except for Effulgent Feathers.
 * The Dragonfolly is a failed clone of Yharon.
