Consuming the Wrong Food

To represent the myriad effects the variety of different foods might have on an individual and varying tolerances, this system implements a simple metric for processing food of the wrong Chirality; When a character attempts to digest food in their stomach of the wrong Chirality, instead of gaining Diet Points, they gain Toxin Points equal to the diet points the food would have provided. Toxin points do not impact the character's metabolism directly and so do not impact whether the character gains or loses weight, but are flushed from the metabolism along with diet points when diet calculations are done.

Toxin Buildup

The real danger in consuming opposite-chirality food and drink comes from allowing the toxins to build in your system. Most characters can handle a certain amount of this buildup without issue, experiencing no more harmful symptons than mild indigestion or intestinal discomfort. This limit for 'safely' processing Toxin Points is represented by your Toxin Limit, which is equal to your Constitution Modifier (minimum 1). A character's metabolism can handle this many Toxin Points in their system before they begin to see any adverse effects.

Each time a character gains an amount of Toxin Points above this limit, they must make an Eating check or Constitution saving throw (DC 8 + the number of Toxin Points in their metabolism pool). On a failure, they gain a level of exhaustion. They also gain the Poisoned condition, which lasts until they complete a Long Rest.

Purchasing the Right Food

Most places that see plenty of Galactic traffic will have businesses and stores that offer both Levo and Dextro-based food products, and they can usually be found for around the same price. In areas that see less diverse traffic or are more specific in their clientele, the food usually skews mostly or entirely to the appropriate chirality, and any food you can find of the opposite chirality might be more expensive by comparison. In most places, the common food will be Levo-based, but in Quarian or Turian-centric areas such as the Migrant Fleet or on Palaven, it will be Dextro-based. Products are usually clearly labeled, but not always.

Someone trying to identify whether an unlabeled food product is Dextro or Levo-based can make an Intelligence(Investigation) check with a DC of 12, correctly identifying the food's Chirality on a success.

Most people can immediately tell whether a food product is based in the wrong chirality once consumed, however, as either the taste will be off or it will sit poorly in the stomach. The DC for the Investigation check to recognize that you have just consumed wrong-chirality food is only 5.

Angara - Electrometabolism (Ancestral)

Angara have somewhat more control over their physiology than most races. During a long rest, an Angara can add or remove exercise points from their metabolism up to their proficiency bonus.

Asari - Charismatic Feeder (Cultural)

When you take the Force-Feeding Action, you can use your Charisma modifier with your Athletics proficiency rather than your Strength modifier for the roll.

Batarian - Competetive Eating (Cultural)

Whenever you roll to stuff yourself, the amount you increase your stomach capacity by increases by 1 pound for each ally you can see wtithin 30 feet (to a maximum of +5).

Drell - Reptilian Dormancy (Ancestral)

If you do not move on your turn, your can use your bonus action to instantly digest a number of pounds of food in your stomach up to your Proficiency bonus, adding them to your Diet points for the day and releasing a burst of gas that imposes disadvantage on attack rolls made by enemies within 5 feet of you until the start of your next turn. You can do this a number of times equal to your Constitution modifier, regaining expended uses at the end of a long rest.

Elcor - Durable Physiognomy (Ancestral)

You have resistance to damage caused by overeating.

Geth - Artificial Metabolism (Ancestral)

Geth can choose whether or not to do diet calculations at the end of each of their long rests. If they choose not to, any Diet and exercise points remain in their metabolism until they decide to do diet calculations at the end of a long rest.

Hanar - Levitation Assistance (Ancestral)

So long as your Contra-Gravitic Levitation racial feature is active, you may add your Wisdom modifier to your other attributes when determining your Bulk, Flex, and Inflation limits.

Human - Natural Glutton (Cultural)

Humans are culturally insatiable creatures, and take just as well to food as anything else. You have proficiency in the Eating skill.

Krogan - Voracious Predator (Ancestral)

As an Action, you can force a character with less hit points than your Character Level + your Constitution modifier to make a Strength Saving throw (DC 8 + your Proficiency bonus + your Constitution modifier). On a failure, you swallow them whole.

A creature you swallow in this way begins suffocating and is blinded, restrained, and incapacitated while in your stomach, and the creature contributes 1/10th of its weight for the purpose of determining your fullness. If you fall to 0 hit points while you have a creature in your stomach, it is neither restrained nor incapacitated and can exit your body using 5 feet of movement, ending the blindness. If a creature falls to 0 hit points in your stomach, they turn into into an amount of Fatty food equal to 1/10th their total weight. Any edible items are immediately consumed with the creature, and activate their effects on you. Any inedible items are coughed up on your next short or long rest.

Once you use this feature, you cannot do so again until you finish a long rest.

Prothean - Psychometric Hunger Sense (Ancestral)

A prothean's psychometric capacities allows them to read the metabolic states of others. As an action, you can touch another creature, immediately learning their current stomach capacity (if any) as well as how much food is in their stomach. Doing so also allows you to impart a sense of hunger into them, granting you advantage on Force-Feeding checks against them for the next minute. Once you use the second part of this feature on a creature, that creature is immune to that effect until the end of your next long rest.
