Cloudkill in D&D 5th Edition
In battles, different spells serve different purposes. While some spells, like fireballs and lightning bolts, cause immediate destruction, others, like Cloudkill, work more subtly. Cloudkill creates a deadly fog that slowly suffocates anything it touches.

Cloudkill’s fog is quiet and yellowish-green, unlike flashy spells with big explosions. It doesn’t cause instant damage but brings a slow and painful death to those trapped inside. This makes it a tricky spell to use because it raises serious moral questions.
However, Cloudkill can still be helpful in battles. It can force enemies out of hiding or control where they can go on the battlefield. But using it comes with a price – innocent people might get hurt.
This blog dives into Cloudkill’s details: how it works, what it does to different creatures, and how to use it in battles. But it also talks about the ethics of using such a deadly spell. We’ll discuss whether the benefits outweigh the harm it can cause.
By the end of the blog, you’ll understand Cloudkill not just as a spell but as something that challenges us to think about the balance between strategy and morality in magic.
So, get ready, magic users (and those who are cautious of them), as we uncover the mysteries of Cloudkill.
Mechanics of Cloudkill
Cloudkill is a potent 5th-level spell that unleashes a deadly cloud of poisonous vapors. Understanding its mechanics is crucial for casters wielding its power and those facing its wrath.

The mechanics of the spell are such that when cast, it creates a dense, rolling cloud of poison that stays close to the ground and spreads around corners, seeping into lower levels.
Any creature that enters the spell’s area must succeed on a Constitution saving throw or take significant poison damage, and the cloud moves away from the caster at the start of each turn, persisting and potentially affecting new areas.
This spell is particularly feared for its ability to fill large spaces with lethal gas, making it a formidable weapon in a spellcaster’s arsenal. The strategic use of Cloudkill can turn the tide of battle by creating zones of denial and forcing opponents to reposition or risk succumbing to its deadly embrace.
By understanding these mechanics, casters can utilize Cloudkill to control the battlefield and devastate their foes. However, opponents aware of its workings can strategize to mitigate its effects and turn the tide of battle.
Cloudkill: Mastering the Art of Poisonous Warfare
Cloudkill is a powerful spell that creates a poisonous mist for attacking and defending. Here’s how you can use it effectively:
Attacking Moves
- Controlling the Battlefield: Place Cloudkill in spots that block enemies or control essential areas. This makes it hard for them to move where they want.
- Creating Danger Zones: Cloudkill makes areas dangerous for enemies to enter. This helps you control where they go and can set them up for attacks.
- Causing Continuous Damage: The poison in Cloudkill keeps hurting enemies over time. Even though it might not break a lot initially, it weakens them for a big attack later.
Defensive Strategies
- Protecting Your Friends: Put Cloudkill around your group or important places to keep enemies away. This is really good against enemies who fight up close.
- Defending Narrow Paths: Put Cloudkill in narrow places to stop enemies from coming through quickly. They’ll either get hurt or have to find another way, giving you time to get ready.
- Making Enemies Move: Cloudkill can mess up how enemies are standing and make them leave good spots. This lets you attack them more easily.
Combining Cloudkill with Other Moves
- Cloudkill and Hold Person: Use Hold Person on an enemy to freeze them, then put Cloudkill around them. They’ll take a lot of damage and won’t be able to escape.
- Cloudkill and Pushing Spells: If you can push enemies, push them into Cloudkill. They’ll get hurt while trying to get out.
- Cloudkill and Big Damage Spells: First, use Cloudkill, then follow up with a spell like a fireball to hurt everyone inside even more.
When you get good at using Cloudkill along with these tactics, you can control the battlefield and win fights easily. Remember, using Cloudkill smartly is the key to winning battles. Let the poisonous cloud help you defeat your enemies and become a master of the battlefield!
Mitigating Risks
This section dives into strategies for minimizing harm and maximizing success:
Positioning and Area Control
In spells like Cloudkill, careful positioning is paramount to ensure allies’ safety. Casters must have a keen sense of battlefield awareness,considering the current locations and potential movements of friends and foes.
The risk of friendly fire can be significantly reduced by strategically placing the spell in areas likely to be occupied by enemies and avoided by allies. Additionally, clear communication with fellow combatants about the intended area of effect can prevent accidental harm.
Dispersal Methods
Sometimes, controlling the duration and area of effect of a spell-like Cloudkill is necessary to prevent extended harm. This can be achieved through natural strong winds or magical means such as the Gust of Wind spell. Other spells influencing air currents or environmental conditions, like Control Weather, can also effectively disperse the poisonous gas, mitigating its potential risks.
Considerations for Dungeon Masters

For Dungeon Masters, Cloudkill offers a tool to design tactically challenging encounters and pose ethical considerations. By introducing this spell into a scenario, DMs can compel players to think creatively and make difficult choices, such as using potent but dangerous magic that could have unintended consequences. This can lead to deeper engagement with the game’s moral complexities and enhance the storytelling experience.
Countering Cloudkill
Cloudkill is a deadly poison cloud that can quickly turn the tide of any encounter. Here’s how to prepare for it and survive its noxious fumes:
Prevention
- Be wary of well-sealed chambers or trapped passageways. Cloudkill is often used to booby-trap locations. Look for signs of tampering or hidden mechanisms, and be cautious about entering confined spaces.
- Consider the enemy. If you’re facing foes known for using poison or environmental hazards, prioritize spells and equipment that offer protection.
Defensive Measures
- Resistance is key : Spells like Potion of Poison Resistance or the Stone Skin class feature can significantly reduce the damage you take from Cloudkill.
- Shield yourself with magic : Spells like Protection from Poison or Heroes’ Feast can grant an advantage on saving throws against Cloudkill’s poison.
Mobility
- Move with haste : If caught in the cloud, use high movement speed to escape the area quickly. Spells like Expedite or fleet-footed abilities can be lifesavers.
- Teleportation offers escape : You can instantly escape the cloud’s reach by accessing teleportation magic like Dimension Door or Misty Step.
Ethical Considerations in Using Cloudkill
The spell Cloudkill conjures a deadly fog that spreads rapidly, capable of ending life indiscriminately. Its use raises profound ethical questions, particularly in the context of its potential to harm innocents and the environment.

Justifiable Scenarios
- Self-Defense: In a situation where lives are at imminent risk, and no other options are available, using Cloudkill could be argued as a necessary evil.
- War: Such spells might clear strategic locations during warfare, albeit with heavy moral consequences.
Reprehensible Scenarios
- Civilian Areas: Deploying Cloudkill in areas populated by non-combatants is ethically indefensible, violating principles of proportionality and discrimination in combat ethics.
- Ecological Impact: The spell’s residual effects could devastate ecosystems, an act that could be deemed ecologically irresponsible and morally reprehensible
Character Perspectives
- Lawful Good Paladin: A paladin, sworn to uphold justice and protect the innocent, would likely abhor the use of Cloudkill. They might argue that its indiscriminate nature goes against their oath to harm no innocent.
- Chaotic Neutral Rogue: A rogue might consider Cloudkill a tool like any other to be used when it serves their purpose. Their moral compass might extend beyond the broader implications of such actions, focusing instead on immediate benefits.
In conclusion, while potent, Cloudkill is fraught with moral complexities. It is a stark reminder of the heavy responsibilities of those who wield great power and the ethical considerations they must weigh in its use.
