# D&D 5e Weight Gain Rules
This guide provides rules to add weight-related fetish content to a D&D 5e campaign. The fetishes involved in this document include weight gain, struggling with weight, stuffing, stuckage, and feederism, though the degree to which each is involved in the game depends heavily on your group and the campaign.
Gaining weight is not a quick process, at least if magic is not involved. This guide assumes that most weight gain is accomplished the good old fashioned way: with a hearty diet and insufficient exercise. While gaining weight through magic, or as the result of a curse, is a common trope that may appear in your game, it is outside the scope of this document.
This guide divides weight-related content into two phases: gaining weight, and adventuring while fat. Gaining weight is a process that takes place over weeks or months, and is therefore usually reserved for downtime and travel. The choices a character makes in how they spend their time determine whether their belts start to tighten as they wait for their next adventure.
Adventuring while fat covers the more heroic endeavors the characters go on, and how their changing weights affect them. While actually gaining weight is uncommon in this phase, there are many situations characters can find themselves in where their weight is at the forefront of the scenario. Crawling into tight dungeons becomes harder, food becomes more tempting, and NPCs may react to their new girths in a variety of ways. To encourage roleplaying these scenarios, players earn Indulgence Points by roleplaying, which they can then spend on various perks.
## Gaining Weight
While an adventurer is between adventures, they often live a very different life from being out on the road: carousing, resting, enjoying life before they will be forced back out into the fray. Depending on how indulgent their relaxation is, living large like this may result in a quite a few pounds creeping onto their bodies if they're not careful.
### Downtime
At the start of a week or month of downtime, you decide what type of lifestyle you live. This determines your potential for gaining; the more opulent your lifestyle, the richer the food you get to enjoy, and the less physical activity you are likely to engage in. If you do gain weight, this determines the dice you would roll to see just how much.
##### Variant: Speedy Gaining
This guide attempts to approximate a semi-realistic rate of weight gain. Even a character eating as much as possible will rarely gain more than 30-40 pounds in a month.
If your group prefers to roleplay a more rapid version of weight gain, the easiest solution is to multiply the amount of weight gained during downtime by a factor of 1.5 or 2.
\columnbreak
##### Lifestyles
Lifestyle | Cost (per day) | Gain Die | Max portion size
--- |:---:|:---:| ---
Wretched | — | d2 | Meager
Squalid | 1sp | d2 | Average
Poor | 2sp | d4 | Average
Modest | 1gp | d6 | Plenty
Comfortable | 2gp | d8 | Generous
Wealthy | 4gp | d10 | Excessive
Aristocratic | 10gp | d12 | Hedonistic
#### Portion Sizes
You also choose your portion sizes - do you stop eating when you're no longer hungry, or do you keep going until you're truly sated? The amount you consume per day modifies your daily lifestyle costs by a multiplier shown in the Portions table below. Note that not all portion levels are available to all lifestyles, as shown on the Lifestyles table above.
Some effects raise or lower the effective Portion Size you consume during a rest. This can raise the Portion Size above the level normally allowed by your Lifestyle. If your Portion Size would be raised above Hedonistic, you gain an Indulgence Point for each additional size instead. Your Portion Size cannot fall below Starvation.
##### Portion sizes
Portion Size | Lifestyle Cost Multiplier | # of Gain Dice
--- |:---:|:---:
Starvation | 0.5x | -2
Meager | 0.75x | -1
Average | 1x | 0
Plenty | 1.25x | 1
Generous | 1.5x | 2
Excessive | 2x | 3
Hedonistic | 2.5x | 4
#### Losing Weight
If the number of gain dice becomes negative, they become d4s, regardless of your lifestyle. When those dice are rolled, you lose that amount of weight, rather than gaining it. For instance, someone living a Comfortable lifestyle on Starvation portions would roll -2 dice, so they would roll 2d4 to determine how much weight they lose, even though their Gain Dice are normally d8s.
#### Starvation
A starvation diet is unsustainable and unhealthy. For each month a character’s Portion Size is set at Starvation level, they gain a level of Exhaustion which cannot be removed until they spend a week recuperating and receiving portions of at least Meager size.

##### Additional Modifiers
Modifier | Effect
--- | ---
Exercise Regimen | DC 11 Strength (Athletics) or Dex (Acrobatics) check:
Reduce the number of gain dice rolled by 1. On a roll of 20+, reduce it by 2.
Manual Labor | DC 11 Strength (Athletics) check:
Reduce the number of gain dice rolled by 1.
Eating Encouragement | If someone is plying the character with food at least several times a week, when rolling for weight gained, roll twice and take the higher of the two results.
Lazing Around | If the character spends most of an average day just being idle, sleeping, and eating, increase the number of gain dice rolled by 1.
Dieting | DC 11 Wisdom check:
On a success, when rolling for weight gained or lost, roll twice. Take the lower result.
On a failure, treat your portion size for the rest as 1 higher, at cost.
Home Cooking | DC 13 Wisdom (Cooking Utensils) check:
Treat the character's portion size as one tier higher, for free. Up to three other humanoids may benefit from this.
Scavenging|DC 13 Dex (Stealth) or Wisdom (Survival) check:
Treat your portion size as one tier higher, for free. On a roll of 20+, treat your portion size as two tiers higher.
Carousing|If the character spends their time Carousing, increase the number of gain dice rolled by 1.
Traveling on Foot|If the character spends an average day traveling 8 hours on foot, reduce the number of dice rolled by 1.
#### Traveling
While not downtime in the typical sense, overland (or overwater) travel takes time, during which a character’s weight might fluctuate. Typical foot travel, consuming rations as your primary form of sustenance, can be considered equivalent to a Modest lifestyle, without the daily cost. One ration per day is the equivalent of an Average portion size, while two per day is Plenty.
If a traveler is walking on foot, they also apply the Traveling on Foot modifier, and roll one fewer gain die. If the traveler is riding in a coach or boat and makes no effort to exercise during rests, they apply the Lazing Around modifier. There is no modifier for riding a mount, as that can be considered average physical activity. Other modifiers apply as relevant to the situation; for instance, a character who is well-supplied with spices and Cook’s Utensils could do some Home Cooking during travel to spice up their rations.
#### NPC Weight Gain
NPCs follow different rules for weight gain. Each NPC falls into a weight category on a track ranging from 1 (Skinny) to 10 (Massive). An NPC is generally at an equilibrium based on their lifestyle and won’t gain or lose weight unprompted, but changes in their environment (or influence from the PCs) may move them up or down the track.
When an NPC recieves extra portions above Average during downtime, roll 1d10 and add the number of extra portions (for instance, Generous portions grant +2). Compare the result to the NPC's current Weight Level. If the result is higher, their Weight Stage moves one step up the track. If it is 5 or more higher, they move up two steps.
Level| Weight Stage | Modifiers
:---:|--- | ---
1|Skinny|—
2|Thin|—
3|Average|—
4|Thick|—
5|Chubby|—
6|Overweight|-1 to Athletics and Acrobatics
7|Fat|-2 to Athletics and Acrobatics
8|Rotund|-3 to Athletics and Acrobatics
9|Overflowing|-4 to Athletics and Acrobatics
10|Massive|-5 to Athletics and Acrobatics

## Weight Levels
Your character’s Weight Level is determined by how high their weight is compared to an average member of their race. Determine the average weight for your race, then divide it by 2. That value is the interval between Weight Levels. For each interval between your weight and the average weight of your race, you increase your Weight Level by 1.
For instance, an average elf is between 100 and 140lbs, so 120 is the average number. Dividing 120 by 2 gives an interval of 60, so for every 60 pounds a character reaches above 120, they increase 1 Weight Level. This is shown in the table below.
For each Weight Level a character has, they take a -1 penalty to Dexterity (Acrobatics) and Strength (Athletics) checks.
#### Example Weight Levels
A character can have any number of these points stored up, and can spend them for various perks. Unless the description says otherwise, a perk can be purchased at any time. If a perk indicates it is single-use, its effects are applied immediately, and the perk must be purchased again to re-gain the effect.
##### Customizing Indulgent Behavior
There are many weight-related scenarios available for roleplaying, but not all of them are good fits for every group. Some may want to leave out the teasing or stuckage aspects. Others may want to add a focus on eating messily, or behaviors like burping. Modifying the list of behaviors that earn Indulgence Points is a good way to influence which types of content players bring to their roleplaying.
##### Spending Indulgence Points
Perk | Cost | Effect
--- |:---:| ---
Plump Up | 1 | **Single Use**
After a long rest or during downtime, gain 2 pounds. You may spend any number of points on this effect during downtime, but may only spend up to 1 + your Weight Level during a long rest.
Thickspiration | 1 | **Single Use**
Reroll one ability check, attack roll, or saving throw, provided you can justify how your history of gluttony assists you. You may only use this once per roll.
A Fruitful Season | 1 | **Single Use**
During downtime, when you roll for weight gained, reroll one gaining die, and choose which result to use. You may use this multiple times per instance of downtime.
Superior Flavor|2|**Single Use**
Purchase this while eating a meal to gain a d4. Any time before your next meal, you can spend that d4 to roll it and add the result to an attack roll, ability check, or saving throw.
If you became stuffed as a result of the meal, the die is a d6 instead.
Double-Check the Scale|2|**Single Use**
When you feed an NPC during downtime and they don't gain any weight, reroll the d10, adding the same modifiers.
Fast Digestion|3|The Stuffed and Overstuffed conditions last half as long for you.
Binge Eater|4|During downtime, the maximum portion size available to your chosen lifestyle is increased by 1 tier. For instance, if you are living a Modest lifestyle, the maximum portion size you can choose becomes Generous, rather than Plenty. You may purchase this perk multiple times, but the cost is increased by 1 each time.
Competitive Eater|5|You gain proficiency in the Eating skill. This skill is used when the amount of food you can eat, or the speed at which you can eat it, is called into question.
If you already have proficiency in Eating, you may take this again to gain Expertise.
Frequently Stuck|5|You're used to getting stuck in small spaces and it isn't the hardship that it once was.
Attacks against you don't gain advantage while you're squeezing through a narrow space, and you provide full cover to those behind you.
Allies who attempt to free you have advantage on their Strength (Athletics) checks to do so.
Stretched Stomach|5|You require 50% more food to become stuffed, but can also eat 50% more when successfully stuffing.
Persuasive Feeder|5|When you use the Help action to assist someone’s Eating check, they may use your Persuasion modifier in place of their Eating modifier.
One More Slice|5|When you feed an NPC during downtime, add 1 to the d10 roll.
\pagebreakNum
##### Spending Indulgence Points (continued)
Perk | Cost | Effect
--- |:---:| ---
Imposing Bulk|5|Once per long rest, you may add your Weight Level to an Intimidation check you make against a humanoid that is skinnier than you.
Refined Palate|6|When your Lifestyle is Wealthy or greater and you roll for weight gained, you may reroll any dice that come up as a 1 or 2, keeping the second result.
Gourmand|8|Your elevated palate allows you to get more out of a good meal than most. Once per long rest, when you stuff yourself, you gain Temporary Hit Points equal to half your level (rounded up).
Fast/Slow Metabolism|8|Choose Fast or Slow.
**Fast:** You roll one fewer Gain Die during downtime.
**Slow:** You roll one additional Gain Die during downtime.
This perk can only be taken once.
Down In Front|8|**Requires Weight Level 3+**
When you provide cover from a ranged attack against a creature, you provide 3/4 Cover (+5AC).
Soothing Hands|8|You can perform a belly rub to attempt to ease the suffering of a character with the Overstuffed condition. Make a DC 13 Dexterity (Sleight of Hand) check. On a success, the character is no longer Overstuffed, and if they wish to continue eating, they can retry their eating check against the same DC they failed.
Once a character has received a belly rub, they cannot benefit from another one until they finish a long rest.
Expert Feeder|8|During downtime, you may specify one character to be the main recipient of your feeding efforts. If they are a PC, they roll an extra Gain Die this downtime. If they are an NPC, increase their Portion Size once for free.
Bottomless Pit|10|You have advantage on Constitution (Eating) checks to avoid becoming Overstuffed.
As long as you are not Overstuffed, you may always attempt to continue eating. Each additional time you do this while Stuffed, increase the DC of the Eating check by 5.
Weight Training|10|Rather than be burdened by your heft, you have learned to use it to your advantage in certain situations.
Gain one Feat from this document.
You may gain this perk multiple times, taking a different feat each time.
Neighborly Hospitality|10|When you feed an NPC extra portions during downtime, you add 2 to the d10 roll for each portion size above Average, rather than 1.
Well-Padded|10|**Requires Weight Level 1+**
Your plush form is better at absorbing blows, simply due to your abundant mass.
After you complete a long rest, you gain Temporary Hit Points equal to three times your Weight Level. You may regain these temporary hit points on a short rest by eating a meal.
You have advantage on Constitution saving throws made to avoid the effects of cold climates, but disadvantage on ones made to avoid the effects of hot climates.
Explosive Growth|10|Whenever you roll the maximum value on a Gain Die, roll one additional Gain Die of the same type and add it to the total. If the additional dice roll a maximum value, do not roll additional ones.

## Weight-Related Feats
These feats can be gained through the spending of Indulgence Points, but if taken in lieu of an Ability Score Improvement, they also provide a +1 bonus to their associated attribute.
### Heavyweight Champ (Str)
You are adept at using your weight to dominate your enemies on the battlefield.
When you make a grapple, trip, or shove attack (or are targeted by those attacks), your weight penalty adds to your Athletics check, rather than subtracting from it.
At the start of each of your turns, if you are grappling an opponent, you may inflict Bludgeoning damage to them equal to two times your Weight Level.
When you follow an Exercise Regimen during downtime, you have advantage on the Strength (Athletics) check as long as your portion size is at least Plenty.
### Surprising Agility (Dex)
You have grown very comfortable with your larger body, and can move in ways others rarely expect.
When you are targeted by a grapple or shove attack, or attempt to escape a grapple, your weight penalty adds to your Acrobatics check, rather than subtracting.
Your weight penalty does not subtract from Acrobatics checks to avoid becoming stuck, or escaping from being stuck.
You can hide in a smaller space you could normally fit in. Doing so grants you advantage on your Stealth check, but you must also make a Dexterity (Acrobatics) check to avoid becoming stuck. On a failure, you are Restrained.
### Iron Stomach (Con)
The intensive workout you have put your digestive tract through has made you resistant to many harmful poisons and other nauseating effects.
Whenever you make a Constitution saving throw against poison, you may add your Weight Level to the result.

A well-fed figure can alter the fabric of many a social encounter. When you gain this feat, choose one of the following situations.
**Belle of the Banquet:** During a meal or other social event involving food
**Alluring Silhouette:** During seduction, or any other attempt to flaunt your sensuality
**Stately Figure:** During a situation where you take the role of an authority figure
Whenever you make a Charisma ability check in your chosen situation, you may add your Weight Level to the result of the check.
Additionally, you have advantage on checks made while Carousing.
