Yharon, Dragon of Rebirth is a boss which can be fought as soon as the Lunatic Cultist and The Dragonfolly are defeated, but is intended to be fought after The Devourer of Gods. Defeating Yharon is essential to progression, as he grants access to Auric Bars, which are needed to craft the Auric Quantum Cooling Cell and Altar of the Accursed as well as an array of powerful equipment.

Spawn

Yharon does not spawn on his own, and requires the player to summon him by using the Blessed Phoenix Egg.

Behaviour

When summoned, Yharon uses a unique spawn animation; he is invulnerable during this.

• The camera pans to Yharon, having been summoned to the far left or far right of the player.
• Moments later, sparkles start to form as Yharon glows reddish-white around himself.
• After a few seconds have passed, Yharon roars to the player, causing a flash of motion blur and visible yellow shockwave.
• The camera quickly pans back to the player, with Yharon beginning his attacks shortly afterwards.

Tips

Trivia

• There is a 1/500 (0.2%) chance for Yharon's title card to read "Grand Yharon", which replaces the sound played when the lower portion appears with an extremely loud, bass-boosted version of his roar. This becomes guaranteed during April Fools.
  • This easter egg is a reference to a user suggestion made on the Calamity Mod Discord server, suggesting to add an upgraded version of Yharon called "Grand Yharon" with "More hp, Visual armor, Scars, Glowing eyes, and tornado attack that follows u."
• Upon defeat, Yharon explodes into around 4000-5000 Chicken Nuggets.
