The **Cumulomenace** (Japanese: 積乱雲 *Sekiran'un*) is an optional Hardmode boss that is intended to be fought right before Cryogen and Pyrogen. Along with Queen Slime, it serves as an introductory boss to Hardmode and is considered the harder option.
Defeating it rewards the player with Aerialite Ore, a few weapons of varying classes, as well as an accessory.

## Spawn

The Cumulomenace does not spawn on its own, and requires the player to use a Puffy Abomination while at around the height Floating Islands are found. The boss does not enrage nor will it despawn when the player descends to surface level.

## Behavior

When spawned, the Cumulomenace will descend from the sky accompanied with the typical boss roar. Two seconds later, it will start to absorb cloud blocks that seemingly appear out of nowhere for five seconds before causing a small burst of clouds and beginning the fight. Cumulomenace fights by teleporting around the player and utilizing an array of different attacks at random. After executing an attack, Cumulomenace will teleport to another random position before teleporting again to execute the next attack.

### Attacks

#### Phase 1

* [Attack A] Cumulomenace teleports at random positions around the player, firing cloud bullets  towards them. The attack is repeated six times. Each time another bullet is fired, any bullet fired prior will redirect itself to the boss.
* [Attack B] Cumulomenace telegraphs with a harmless line of trajectory pointing toward the nearest player for a second before charging towards the spot where the line last pointed to and stopping a split second after, releasing cloud bullets  in ten different directions around it.
* [Attack C] Cumulomenace charges up before unleashing a volley of cloud bullets  in rapid succession following a circular pattern in one direction.
* [Attack D] Cumulomenace teleports to either the left or the right of a random player, following with a horizontal charge attack. This is repeated for three turns. A spread of four cloud bullets  is shot towards the nearest player behind Cumulomenace after stopping proceeding the third charge attack.

#### Phase 2

* After reaching 66% of its HP, Phase 2 will begin. Cumulomenace spins around frantically in a similar fashion to the Eye of Cthulhu when transitioning to its second phase, emitting puffs of clouds before changing its appearance and the fight resumes. This is followed with Rain.
* Phase 2 retains the same attacks as Phase 1, but with the following changes:
	+ For Attack A, Cumulomenace shoots either three or four cloud bullets  instead of one. The bullets are no longer redirected towards the boss following any subsequent shot.
	+ For Attack B, Cumulomenace shoots cloud bullets  in sixteen different directions instead of ten.
	+ For Attack C, Cumulomenace unleashes a volley of cloud bullets  in two opposite directions.
	+ For Attack D, the attack overall is executed slightly faster than in phase 1, with the spread-shot releasing seven cloud bullets .
* Phase 2 introduces two new attacks:
	+ [Attack E] Cumulomenace charges in a horizontal direction above a random player for a few seconds, laying down rainclouds which will rain damaging droplets. These clouds take one damage point per hit but only require very few hits before disappearing in a little puff. They disappear on their own after 15 seconds if the player leaves them be.
	+ [Attack F] Cumulomenace summons four clouds around itself that orbit around it. The clouds shoot water blasts towards the nearest player. The water blasts are much faster than normal.

#### Phase 3

* After reaching 33% of its HP, Phase 3 will begin. Cumulomenace once again spins around frantically before changing its appearance like in phase two. This is followed with a Thunderstorm.
* Phase 3 retains the same attacks as Phase 1 and Phase 2, but with the following changes:
	+ For Attack A, all cloud bullets  are replaced with blue lightning bolts similar to the ones fired from a Shockstorm Shuttle. They inflict the Electrified debuff for 2 seconds.
	+ For Attack B, just like Attack A, all cloud bullets  are replaced with blue lightning bolts.
	+ For Attack C, Cumulomenace unleashes a volley of cloud bullets  in three directions.
		- For the duration of the entire attack, a blue lightning bolt is fired towards the nearest player every second.
	+ For Attack D, all cloud bullets  are replaced with blue lightning bolts and nine are released instead of seven.
	+ For Attack E, a new variant of rainclouds are placed down. These rainclouds burst into four blue lightning bolts orthogonally upon disappearing. If they disappear on their own, the bolts are fired diagonally. If they disappear from taking too much damage, they fire horizontally and vertically.
	+ For Attack F, the four clouds are replaced with lightning orbs  that fire five bolts of lightning at the player. The lightning bolts as well as the orb itself inflicts the Electrified debuff for 3 seconds.
* Phase 3 introduces one new attack:
	+ [Attack G] Cumulomenace telegraphs on a random player with a row of  either vertically, horizontally or diagonally towards either direction. The row of  locks on said player for a very brief moment before becoming stationary, followed by a burst of electricity on each  shortly after. Any player caught within burst radius will be inflicted with the Electrified debuff for 3 seconds.

#### Desperation Phase

* Once Cumulomenace's HP has been fully depleted, it will enter its desperation phase.
	+ It starts off with a variation of Attack C in Phase 3 where rather than having the cloud bullets  fired from the Cumulomenace itself, they are absorbed into the boss instead. After that, Cumulomenace fires blue lightning bolts towards the nearest player in rapid succession. Following that, a bunch of  will start to appear in rapid succession at random positions around Cumulomenace which will disappear in a burst of lightning much like in Attack G. Finally, Cumulomenace explodes into a puff of clouds, the weather returns to normal and the fight ultimately concludes. The player can thereafter receive Cumulomenace's drops. If all players are slain before the end of the phase, Cumulomenace will simply vanish and the fight is lost.

### In Expert Mode

* Attack A in Phase 1 is repeated eight times.
	+ Attack A in Phase 2 and 3 has either four or five cloud bullets  / blue lightning bolts fired.

* For Attack B, all projectiles move faster.
* For Attack C, cloud bullets  are fired towards the nearest player every second for the duration of the entire attack for Phase 2.
* For Attack D, Cumulomenace charges four times.

### In Revengeance Mode

* For Attack C, cloud bullets  are fired in eight different directions two seconds after the attack ends.
* For Attack D, the charge attack is no longer horizontal and can aim toward players in any direction. The spread shot can also aim in any direction
* For Attack E, rainclouds in Phase 3 leave behind 4  after disappearing which will then disappear into a burst of electricity 5 seconds later.

For Attack F, Cumulomenace teleports to a random position around a player and repeats this attack after the first batch of lightning orbs  disappear.

* For Attack G, another row of  is telegraphed on the selected player perpendicular to the already-existing row.
* Right as the transition to Phase 2 or 3 ends, cloud bullets  / blue lightning bolts are fired in 16 different directions. These projectiles move at high speeds.

### In Death Mode

* For Attack A in Phase 1, two cloud bullets  are shot side by side.
* For Attack D, the charge attack is performed back to back similar to the Eye of Cthulhu in Expert Mode. The spread shot takes a second to occur but is then carried out like normal.
* Attack B repeats itself once.
* For Attack E in Phase 3, blue lightning bolts are shot in all eight directions regardless of the circumstances behind them disappearing.
* For Attack F, the lightning orbs  will slowly navigate their way towards the nearest player.
* The duration before Cumulomenace moves onto its next attack is reduced slightly.
* During its desperation phase, the cloud bullet  absorption attack lasts noticeably longer and the beam of blue lightning bolts will home in on the nearest player ever so slightly.  appear in twos side by side horizontally or vertically.

### In Malice Mode

* Phase 1 is entirely scrapped and the player only fights Cumulomenace in Phase 2 and 3.
* For Attack A, the cloud bullets  / blue lightning bolts redirect themselves towards the nearest player after the next spread of bullets are shot. They only do this once.
* Attack B repeats itself twice.
* For Attack C, volleys of cloud bullets  are fired in three directions in Phase 2 while volleys of blue lightning bolts are fired in four directions in Phase 3.
* For Attack D, the spread of projectiles following the final charge attack fly through much faster and after 3 seconds, redirect themselves back to the point from where they were fired.
* For Attack F, the lightning orbs  spawned around Cumulomenace will no longer slowly chase after the player. However, a row of lightning orbs  spawns above a player spacing out from one another shooting a single blue lightning bolt both upwards and downwards before disappearing. The next row appears three seconds later.

### On the For the worthy seed

* Cumulomenace becomes 50% smaller.
* All of Cumulomenace's projectiles explode on contact.
* Any  that doesn't move will regularly fire blue lightning bolts towards the nearest player every second.
* The world is plunged into a Thunderstorm no matter the phase and will last even up until a few minutes after the Cumulomenace has been defeated.
* For every attack that involves the Cumulomenace itself to move, it moves 75% faster.

### Simultaneously in Malice Mode and on the For the worthy seed

* Cumulomenace is 75% smaller.
* All cloud bullets  are replaced with blue lightning bolts.
* The beam of blue lightning bolts during Cumulomenace's desperation phase lasts a full minute.

## Tips

*For more elaborate strategies on defeating Cumulomenace, including weapon and arena recommendations, see Guide:Cumulomenace strategies.*
* Making an arena can potentially increase mobility, which is useful for dodging Cumulomenace's bullet hell attacks.
* Speed-increasing accessories and potions are recommended as the player will find themselves running away from Cumulomenace throughout most of the fight.
* A Shield of Cthulhu can prove useful for countering Cumulomenace's charge attacks.[1]
* Rather than getting rid of the Rainclouds in Phase 3, it is recommended that the player keeps a good horizontal distance from them. This is especially recommended if the player does not possess a piercing weapon or a weapon with a high fire/swing rate.

## Trivia

* The Cumulomenace's theme is **Clouded in Discord**, which was composed by the artist The ExiIed FeIIow, who is also the item's dedicatee.
	+ If the Calamity Music add-on mod is disabled, **Underground Hallow** will play instead.
* If the Boss Checklist Mod is installed, its unique despawn message will be "The Cumulomenace has lost all interest in fighting..."
* The Cumulomenace is a direct homage to the boss of the same name from a Minecraft datapack developed by The ExiIed FeIIow.
	+ Cumulomenace's theme, Clouded in Discord, was composed for its datapack counterpart, hence the boss shown in its music video being a Minecraft boss.
	+ The boss's unique despawn message if the Boss Checklist Mod is installed is a reference to the same message that appears when its datapack counterpart "leaves" once the boss's patience bar fully empties. Patience is a unique mechanic offered by the boss in the datapack counterpart in which the player has to collect randomly appearing special clouds throughout the fight that are highlighted within circling green sparkles before they disappear in order to keep the fight going. This mechanic no longer applies when the boss enters its last phase.
	+ The boss may also be a possible reference to the recurring boss character, Kracko, from the Kirby series as it too, is a cloud with a singular eye.

* Cumulomenace is a portmanteau of the words 'Menace' and 'Cumulonimbus', a dense, turbulent, towering vertical cloud that produces hail and lightning.
* In the mod's source files, the cloud bullet / projectiles are referred to as "kyumshawt" and "kwumshaht" respectively.
