+            Neptune will mostly hover and fly around at high speeds on a ship similiar to the Respawn Ship from SOT.
+            He will fire projectiles at high speeds which cause high AOE damage and inflict strong crushing debuffs.
+            All players will receive a debuff that nearly nullifies wing time while fighting him.
+            At 50% health, he will "throw" Mr Raccoon off the ship to fight on the ground with the player. His AI will be listed in his file.
+            During this time, Neptune will become mildly less aggressive, however still dangerous and on the offensive.
+            At 25% health, he will double his attack speed and movement speed, becoming a frantic danger to players.
+            100 - 50% HP will be Phase 1
+            50% - 25% HP will be Phase 2 (Raccoon fight)
+            25% - 0% HP will be Phase 3
+
+            If Neptune is hit with 2/3/4 (Normal/Expert/Master) cannon balls while above 95% HP, he will throw Raccoon overboard and swap AI (only if this happens in Phase 1):
+            - Neptune will become enraged, tripling attack speed, movement speed, damage, projectile speed, attack range, and reducing all cooldowns by 75%.
+            - He will also become invulnerable, only taking damage over time until being defeated after ~10 minutes.
+            - In the last 30 seconds of this state, he will enter a "final stand" mode where he salutes and fires a massive barrage of projectiles rapidly, before ramming
+            the ship into the floor, causing a humongous explosion (no tile damage) that will insta kill players in range (~70 tiles).
+            - After being defeated in this state, he will drop an item that functions as infinite wood biome-respected alongside a developer vanity set.

+            IDEA: Attack ideas from Neptune
+            - Neptune will occasionally will try and snipe the player(s) with a high damage, high speed trident using predictive aiming. Damage will be 100 - 150 with full armor penetration (ignores defense).
+            - If the player gets in front of the ship, the ship throws fire at the player, dealing 300 damage and inflicting On Fire! or Brimstone Flames for 10 seconds.
+            - The ship will drop explosive barrels that act like mines - when the player gets close they explode for high damage.
+            - During Phase 2, Neptune will throw 6-8 hunting spears overboard straight down, each equally distant from each other, and if the player is hit, it deals 300 damage (full armor pen) and inflicts a custom debuff "Pierced" that reduces healing received by 50% for 10 seconds. Will move slowly.
