Vital Signs: When Your Con Hits Zero

what happens if your constitution score goes to zero

In Dungeons & Dragons, a character's Constitution score is a measure of their health, stamina, and vital force. While it has no skills associated with it and isn't used for attack rolls or determining Armor Class, it is still considered one of the most important ability scores in the game. Constitution saves are common and vital to a character's success, and it increases a character's Hit Points (HP) and HP recovery. If a character's Constitution score is reduced to zero, they automatically fall unconscious and must make death saves to stabilize and avoid death.

You automatically fall unconscious and need to make death saves to stabilize

In Dungeons & Dragons, a character's Constitution score is a measure of their health, stamina, and vital force. While the rules and mechanics of the game don't explicitly state what happens when a character's Constitution score reaches zero, it is implied that the character's health and ability to withstand damage are severely compromised.

According to some sources, when a character's Constitution score is reduced to zero, they automatically fall unconscious and enter a dying state. At this point, the character must make death saving throws, commonly referred to as "death saves," to stabilize and avoid death. These death saves typically involve rolling dice and achieving a certain number of successes or failures to determine whether the character stabilizes or perishes.

The exact mechanics of death saves can vary depending on the edition of Dungeons & Dragons and the specific house rules used by the Dungeon Master (GM). In some cases, a character with a Constitution score of zero might be considered dying, and any additional damage they take could result in failed death saves. Additionally, the character might need to make Constitution saves to maintain concentration or resist certain effects, such as poison or spells that interfere with bodily functions.

It's important to note that the rules regarding Constitution and hit points (HP) are interconnected. A character's HP is influenced by their Constitution modifier, and changes to Constitution can affect their maximum HP. However, the current HP may remain unchanged unless it exceeds the new maximum due to the Constitution increase.

While the specific consequences of reaching zero Constitution might differ in various campaigns and house rules, it undoubtedly represents a critical situation for the character. It underscores the importance of Constitution as one of the most vital ability scores in the game, despite not being directly associated with skills or attack rolls.

You can regain Constitution through rest or magic

If your constitution score goes to zero, you will fall unconscious and start making death saves to stabilize and avoid death. Your constitution score can be reduced by additional damage after your hit points are reduced to zero or less.

You can regain your constitution through rest or magic. One day of rest restores one point of constitution. Similarly, magic restores one point per spell level of the spell used to heal. For example, a 1st-level Cure Wounds spell would restore one point, while the same spell cast with a 4th-level slot would restore four points. It is important to note that potions cannot restore constitution.

Resting and regaining hit points is an important part of the game. At the end of a long rest, a character regains all lost hit points. This may involve taking one or more hit dice during the long rest to gain additional maximum hit points. Additionally, whenever you complete a Short Rest, you can spend one or more Hit Point Dice to regain HP. You roll your Hit Point Dice and regain HP equal to the result plus your CON modifier. You can then decide if you want to repeat this process until you run out of Hit Point Dice.

Constitution is a measure of a character's health, stamina, and vital force, as well as their ability to push themselves beyond their normal limits. It is one of the most important ability scores in the game, despite not having any associated skills in Fifth Edition. Constitution saves are common and vital to a character's success, and it also increases a character's Hit Points (HP) and HP recovery.

Constitution saves become harder and penalties apply

Constitution, or CON, is a measure of a character's health, stamina, and vital force. It is the only ability score that the 2014 Player's Handbook identifies as important to every character. While it has no skills associated with it, it is vital to a character's success as it increases their hit points (HP) and HP recovery. It also contributes to some class and species abilities.

As your Constitution score decreases, making Constitution saving throws becomes more difficult and penalties apply. For example, if your Constitution score is reduced to zero, you will automatically fall unconscious and will need to make death saves to stabilize and avoid death.

Constitution saves can be used to resist dying. For instance, a Barbarian with the Relentless Rage ability can resist dying when their HP drops to zero by rolling a Constitution save with a DC of 10. If they succeed, their HP becomes double their Barbarian class level, and they will need to take a Long Rest before attempting another save.

Constitution saves can also be used to avoid or minimize the effects of poisons, spells that poison, deafen, blind, or otherwise interfere with a body's functions, and malnutrition. For example, if a character eats less than half of their daily food requirement, they must roll a Constitution save (DC 10) to avoid gaining a level of Exhaustion.

It is important to note that the rules for Constitution and HP may vary depending on the edition of Dungeons & Dragons being played and any house rules that the group may have implemented.

Your hit point maximum changes if your Constitution modifier changes

Constitution (CON) is a measure of a character's health, stamina, and vital force. It is the only ability score that the 2014 Player's Handbook identifies as important to every character. Constitution saves are common and vital to a character's success. In addition to saving throws, Constitution increases a character's Hit Points (HP) and HP recovery.

If your Constitution modifier changes, your hit point maximum changes as well, as though you had the new modifier from the first level. This is the case even if your Constitution score decreases, for example, if your character is brought back from the dead. Your current hit points remain the same, but you would have to heal to reach your new maximum hit points.

For example, if you raise your Constitution score when you reach the 4th level and your Constitution modifier increases from +1 to +2, you adjust your hit point maximum as though the modifier had always been +2. So, you add three hit points for your first three levels, and then roll your hit points for the 4th level using your new modifier.

This HP gain is retroactive: if you take a Constitution Ability Score Improvement at level eight and it increases your CON modifier, you'll gain eight HP, one for every level.

You can resist dying at low HP by rolling a Constitution save

In Dungeons & Dragons, a character's Constitution score is a measure of their health, toughness, resilience, stamina, and vital force. It determines their Hit Points (HP) and their ability to withstand damage and push themselves beyond their normal limits. When a character's HP reaches zero, they typically fall unconscious and must make death saving throws (or death saves) to determine whether they live or die. At this point, their fate is typically considered to be "in the hands of fate", and their chances of survival are influenced by spells, features, and bonuses that improve their odds of succeeding on a saving throw.

Death saves are made by rolling a 20-sided die (d20) at the start of the character's turn after they fall unconscious. A roll of 10 or higher is considered a success, while a roll of 9 or lower is considered a failure. The goal is to accumulate three successes before getting three failures. If a character rolls a 1 (a critical failure), it counts as two failures, and if they roll a 20 (a critical success), they instantly regain consciousness with 1 HP.

While Constitution is not directly added to death saving throws, it plays an important role in determining a character's resilience and their ability to withstand damage. A character with a higher Constitution score will have more HP and a greater ability to resist the effects of poison, exhaustion, and other challenges. Additionally, some class features reward characters for having a high Constitution, such as the Barbarian's Relentless Rage ability, which allows them to resist dying at low HP by rolling a Constitution save with a specific difficulty class (DC).

For example, when a Barbarian reaches level 11, they gain the ability to resist death when their HP drops to zero by making a Constitution saving throw against a DC of 10. If they succeed on this saving throw, their HP becomes double their Barbarian class level, and the DC for this save increases by five until they have a long rest. This demonstrates how a character's Constitution can influence their ability to survive in critical situations, even when their HP is depleted.

In summary, while a character's Constitution score does not directly affect their death saving throws, it plays a crucial role in their overall resilience, health, and ability to withstand damage. Additionally, certain class features and abilities may allow characters with high Constitution scores to resist dying at low HP by rolling Constitution saving throws, further emphasizing the importance of this ability score in the game.
