Spirit

"Stop right here, criminal scum, and prepare for justice!"

 is a Pre-Hardmode Boss that can be fought only at night, she is intended to be fought after the Eye of Cthulhu.

While Spirit is alive, her own theme, "Spirit" will play.

Spawn

 * Spirit does not spawn on her own, and requires the player to summon her with a Hastily Crafted Remote at night. Upon summoning her, the player will hear ringtone as in a phone call, alongside a message in chat popping up that says "Connecting... Please, stay on the line." After around 10 seconds, Spirit will teleport above the player and say: "Stop right here, criminal scum, and prepare for justice!", she'll then proceed to pull a weapon out, beginning the fight.

Behavior
The Spirit flies above the player, launching a continuous series of attacks at them, such as launching beams at the player, summoning an orb that shoots in all directions, etc.

Upon reaching 50% HP, Spirit's hood will fall off and she'll say this: "Oh shoes, my transmitter is dead! Do you even know how expensive this stuff is these days?". This is only visual and nothing about the fight will change whatsoever.

Attacks

 * Launches several sword beams at the player, moving incredibly quickly from side to side, making it harder to hit her. This attack happens after every attack;
 * Throws away her weapon and casts a giant orb above her. The orb itself will shoot ice crystals (or, sometimes, fireballs) in all directions, getting hit by any will inflict Frozen (or On Fire) debuff;
 * Casts another orb that instead launches many more knives that curve and go more into the center after a few seconds.

Aftermath

 * Upon defeating Spirit, she will fall down to the ground and enter a dialog with the player. At this moment, Mysterious Person theme will play.
 * She can later be found in the Underground Jungle working on fixing her transmitter. You can give her any food other than Kebab to get early game ores, gems, Life Crystals and obsidian.

After defeating her

 * "I thought it would be easier... Hey, you don't look like a space pirate! Of course you're not! Did I... Ooh! I just got it all mixed up?... But my transmitter got a signal from here... Now it's absolutely irretrievably destroyed! How do I get it back now..." (Upon talking to her for the first time)
 * "The carbon-based life-form is trying to relate to me. What should I do?"
 * "So many answers and so few questions!"
 * "Do you hear this music? Sounds kinda ominous, like something serious is gonna happen."
 * "The air is filling up with... confusion..."
 * "I'm in the middle of something..."

In the Underground Jungle

 * "One day I looked in the mirror and saw my reflection. I've never been so disappointed."
 * "My boss always says I'm good for nothing but nuclear astrophysics and quantum mechanics. It helps a lot, makes me forget all the unnecessary things and focus on what I know best."
 * "'Why can't we be friends, why can't we be friends...'"
 * "No, I don't know who Yuyutsu is. Why you're asking!"
 * "Who were you expecting? The Moon Jelly Wizard?"
 * "You'd better be careful, there's some sort of maniac lurking around, constantly calls me and kills me occasionally. I'm getting pretty tired of it!"

 * "Cooked marshmellow? Now we're talking bussiness, magic man!" (Cooked Marshmallow)
 * "What is that? I'm an eater, not a drinker. The mug will do though!" (Ale)
 * "Woooo~hooooo! Yeah, baby! That's what I've been waiting for! That's what it's all about! Wooooo~" (Bowl of Soup)
 * "Are you sure this is edible? It looks kinda fishy..." (Cooked Fish)
 * "Oh, sorry, I didn't come up with a shrimp-related quote. But I'll take it anyway!" (Cooked Shrimp)

Trivia

 * Spirit's fight theme contained sounds similar to a phone call so her summon item was changed to resemble a phone and have another similar theme as its 'ringtone'
 * Her Yuyutsu and Moon Jelly Wizard quotes are direct references to the Spirit Mod. Yuyutsu is the main developer of the mod and the Moon Jelly Wizard is also a boss in the mod.
 * This also refers that the Spirit mod, Split mod, and the spirit boss all sound very similar to each other.
 * Her summoning line is a reference to the "Stop right there, criminal scum! Nobody breaks the law on my watch!" line from Elder Scrolls: Oblivion, which plays when a guard catches you committing a crime.
 * Her "Why can't we be friends, why can't we be friends..." quote is a reference to a song of the same name made by Smash Mouth.
 * Her maniac quote is about the Terrarian and how the player may occasionally use the Hastily Crafted Remote to kill her.
