Fargo's Mod/Moon Lord (Eternity Mode)

Eternity Mode Moon Lord is a Hardmode. He is a more powerful version of Moon Lord with more attacks and new behavior.

Phase 1
Moon Lord behaves similar to his original counterpart albeit with some new abilities:

Passively inflicts Nullification Curse, granting him immunity to all attacks that do not belong to a specific damage type. This weakness changes periodically and is indicated by rings of fragments of their respective class that count down

Produces an arena of Phantasmal Eyes that prevents escape

Head has reduced life

Phantasmal Spheres accelerate instead of starting at full speed, have a trajectory telegraph, and cannot damage the player while spawning in

Phantasmal Bolts are now fired in wide spreads, accelerate, and have slight homing

Phantasmal Eye homing is significantly weaker

Moves a lot slower

Removed contact damage from both empty sockets and true eyes of cthulhu.

True Eyes are always synchronized and attack slower until core is exposed

Has additional attacks depending on its current vulnerability:


 * Melee: Shoots sprays of 5 homing Fireballs at a 180° angle from each socket, and the fireball spray always launches away from the direction of the player, prior to the socket
 * Ranged: Rains down a storm of lightning from above
 * Magic: Shoots rings of 6 Nebula Blaze from each socket
 * Summon: Shoots spreads of 3 Ancient Lights from each socket
 * All: Shoots Phantasmal Sphere Rings from heart

Phase 2
Vulnerability changes faster when core is exposed

Once core is exposed, discards previous attacks and uses new ones:
 * Melee: Generates massive suns and throws them down, creating 2 vertical and 2 horizontal colossal chain explosions on impact
 * Ranged: Protects its core with a vortex that orbits around the core and sucks in friendly projectiles and retaliates by shooting lightning
 * Magic: Summons random implosions of Nebula Blazes from the arena border and shoots Nebula Blazes that bounce around the arena.
 * Summon: Fires deathrays from its sockets and core around the player, limiting movement
 * All: Shrinks the arena drastically, but does not perform additional attacks.

Tips

 * It's highly recommended to bring more than 1 different class setup with you because of the constant immunity changes. Remember to keep an eye on the fragments and tinted foreground to see what he's currently vulnerable to.
 * Avoid getting hit by the ancient lights in its stardust state, as the debuff cancels your minions.
 * Do not use pure heart, or if you do, turn off creepers in the configuration menu, due to that many of moon lord's attacks deals splash damage, which the creepers can't prevent well, and will only make the fight harder due to the increased hitbox.

Trivia

 * If the Eternity Mode Recolors option is turned on in the Mod Configurations menu, it resembles the original design for Cthulhu prior to being scrapped
 * Prior to 1.3.96, it resembled the Sun Lord from the Terraria Fan Ideas Wiki.
