"The chatter ends here. Prove to me your resolve, and I will show my own."

Nebuleus, Angel of the Cosmos is a post-Moon Lord boss that can be fought after Patient Zero.

While Nebuleus, Angel of the Cosmos is alive, the music Interstellar Isolation will play. While Nebuleus, Angel of the Cosmos' Ultimate Form is alive, the music Hypernova will play instead.

Spawn

Nebuleus is summoned using the Galaxy Stone at night. If Nebuleus' Ultimate Form has been encountered at least once, right clicking the Galaxy Stone will instantly summon her second form.

Behavior

Nebuleus is a stationary boss that floats in place, teleporting between attacks or if the player is too far away. She does not deal contact damage if she is not performing a physical attack. Every time she loses 25% of her maximum health, she will briefly pause and drop two heart pickups.

Nebuleus starts with five attacks but gains more as she enters each new subphase, while also enhancing some of her older ones. Most attacks introduced in a phase will be called out by text appearing above Nebuleus' head.

Upon reaching 1% of her health, Nebuleus will give up and end the fight, dropping her loor after leaving. If the player has negative Alignment, she will offfer the player to either continue the fight or spare her. Choosing to continue will force Nebuleus to enter her Ultimate Form. If the player spares her, they can make another choice after refighting her first form. Nebuleus will drop her loot regardless of the choice.

Attacks

Star Blast - Shoots 3 rings of 8 telegraphed Shooting Stars from herself that spiral outwards, alternating between spinning clockwise and counterclockwise.
- Below 75% health, Nebuleus will launch the second and third rings with less delay.
- Below 50% health, the second ring will be slower and will consist of 10 Shooting Stars instead of 8.
- No longer performs this attack below 25% health.
Starfall - Rains a mass of Starfall projectiles angled towards the player's position.
Piercing Nebula - Quickly throws 2 Piercing Nebulas at the player.
- No longer performs this attack below 75% health.
Star Dash - Performs 4 consecutive predictive dashes towards the player, with the first 3 ending in her emitting a Giant Star around herself. The speed of the dash increases the further the player is from Nebuleus.
Nebula Dash - Vanishes before teleporting 3 times, performing a dash at the player each time. The dashes can only be performed in ordinal directions and their directions are telegraphed at the start of the attack.
- Below 75% health, performs 4 dashes instead.

Below 75% health gains the following attacks:

Piercing Nebula Burst - Teleports around 4 times, firing a Piercing Nebula at the player after each teleport.

Quotes

At the start of the battle:
Nebuleus says the following in sequence:

"Ah, you have brought me here yourself."
"Forgive my prying eyes, for I have been observing thee from afar." (If the player has positive alignment)
- "My eyes have loomed upon thee long enough, it is time to take action." (If the player has negative alignment)
"Thy presence is all-consuming within my thoughts, but I shan't run from this opportunity gifted to me."
"The chatter ends here. Prove to me your resolve, and I will show my own."
"If you lose to me, you may be spared from watchers far greater than I."

If the player has died once to Nebuleus before and has not defeated her yet:

"You... are still alive?"
"You still want to fight?"

Upon reaching 75% health for the first time:

"What purpose drives you? What is your goal?"

Upon reaching 50% health for the first time:

"Do you even have a motive for your actions?"

Upon reaching 25% health for the first time:

"Still fighting? Well I'm not done yet!"

Upon defeat:
Nebuleus says the following in sequence:

"I would appear to be fighting a hopeless battle..."
"Ever since this island suddenly appeared, I have been watching."
"I've seen you be slain countless times, however you never truly die."
"It seems most cannot or simply will not comprehend this."
"But I do."
"Time in the confines of this island seems to be dictated by powers unknown."
"And they are in thy favour."
"Alas, whatever the case may be, I no longer wish to fight you..."
"You hath proven thy resolve." (If the player has positive alignment)
- "Not like I could do anything to stop you." (If the player has negative alignment)
"And I... hath failed once more." (If the player has positive alignment)
- "I hope you find it in thine heart to stop thy rampage." (If the player has negative alignment)
"I will be leaving forthwith, but we can always spar again. Farewell." (If the player has positive alignment)
- "If you don't wish to fight me now, I'll leave you be." (If the player has negative alignment)

If the player has negative Alignment, and chooses to spare her:

"Thank you... At first I thought the concept of mercy was foreign to you."

If the player has negative Alignment, and chooses to continue the fight:

"You still want to fight?"
"Of course it wouldn't be that easy..."
"You've had thy chance at redemption, so don't blame me..."
"... When you die a thousand times!"

Upon transforming into her final form:
Nebuleus says the following in sequence

"I still have this hope in my mind that you're mortal, so even if I can't figure out how to be rid of you..."
"... There are still many foes greater than I!"
"... Epidotra's Protector..."
"... The Royal Knight..."
"... and the Demigod of Light..."
"But enough talk, I'm your opponent!"

Upon defeat in her final form:
Nebuleus says the following in sequence the first time she is defeated:

"... That was all I had."
"And yet I still lost..."
"Fighting you and that traitor have confirmed my suspicions."
"I'm weak."
"I don't deserve being part of their group. I was only a burden."
"If the Demigod ever comes for you, don't let him know I'm still alive."
"I fear what he might think of me, and I don't want to face him."
"To think I'd die again so soon..."
"I really am pathetic."

Aftermath

The Fool gains a different set of dialogue and a different sprite, no longer has shop and happiness options and will leave shortly afterward.
If Ultimate Form has been defeated, the player's Alignment will be reduced by 6.

Notes

While Nebuleus or her Ultimate Form are alive, time will always be frozen at 12:00 AM.
Nebuleus and her Ultimate form take 1.5x damage from physical melee weapons.
If the player has defeated Nebuleus' Final Form and spawns her again, Nebuleus will be replaced by Nebuleus' Mirage. Albeit being a simple aesthetic change, Nebuleus' Mirage will not give quotes.

Trivia

The Bestiary entry for the Nebuleus, Angel of the Cosmos: "..."

The idea for this boss was originally thought of by Kirill Greathly in the mod's homepage.
- Kirill also originally named the boss “Corrupted Star God” until Hallam, the main developer of Mod of Redemption, remade the concept of the boss into what it currently is.
