Cook

"I always cook with rum. Sometimes I even add it to the food"

— Eezle Steinbach

Ships boast large crews and those crews need to eat. The best ship cooks can turn limited ingredients into feasts capable of boosting morale with a single spoonful. Being on an airship can be a rough experience for some. Food is their respite. Cooks often spend their time thinking of new edible creations to make for the crew and its morale. Cooks should have high Constitution scores and proficiency with brewer’s supplies and/or cook’s utensils.
Role Proficiency: The cook can add its proficiency bonus to skill checks, prepare cooked meals and keep food costs low. If the cook is already proficient in the requisite skill to make the check, their proficiency bonus is doubled for that check. The check cannot benefit from more than one feature (such as Expertise) that doubles the proficiency bonus.

Character Level	Role Feature
1st	Bonus Proficiency, Here's a Little Snack
5th	Big Ol' Feast, Tamper Sense
11th	Ration It Out, It'll Do in a Pinch
17th	Brain Food, The Heart of the Ship

Bonus Proficiency: When you accept this role at tier 1, you gain proficiency in cook's utensils. You add double your proficiency bonus to all ability checks you make using this proficiency. The check cannot benefit from more than one feature (such as Expertise) that doubles the proficiency bonus.
Here's a Little Snack: Also at tier 1, you learn the goodberries spell. Wisdom is your spellcasting ability for this spell.
Big Ol' Feast: Starting at tier 2, when you participate in the boost morale downtime task, you can replace the requisite Charisma check with a Constitution check using proficiency in cook's utensils. When you do, you can treat a d20 roll of 10 or lower as a 10.
Tamper Sense: As a tier 2 cook, you gain a supernatural ability to detect food tampering. If you spent 1 minute observing, smelling, and touching food and drinks in an area no larger than 10 feet by 10 feet, at the end of the duration, you can make a DC 15 Constitution saving throw using proficiency in cook's utensils. If your roll is successful, you determine whether or not the food is poisoned, spoiled, or otherwise tampered with. Once you use this role feature, you can't use it again for 24 hours.
Ration It Out: At tier 3, you can spend 1 hour performing a ritual to extend the effectiveness of a magic potion by combining it with food. You must have at least 2 pounds of food and the potion within reach, both of which are consumed at the end of the ritual. At the end of the ritual, make a DC 15 Intelligence check using proficiency in cook's utensils. On a success, the food is imbued with the same benefits of the potion except that it now has 1 use per pound of the food that was imbued (to a maximum of 5 pounds). The food must be consumed in 24 hours or it spoils and loses its benefits. If the check fails, the potion and the food are destroyed and nothing new is created. Once you use this role feature, you can't use it again for 30 days.
It'll Do in a Pinch: Starting at tier 3, you can cast create food and water. Wisdom is your spellcasting ability for this spell. Once you use this feature, you can't use it again for 7 days.
Brain Food: Beginning at tier 4, you can spend 10 minutes consuming food that you did not prepare yourself. From the food, you gain a psychic impression of both the person who prepared the food and the creature or creatures who consumed it (if any). You learn the names of the creatures (if any), their appearance, when they prepared/ate the food, and one or two important details each about them. The information you learn is accurate. What you learn is the GM's discretion.
The Heart of the Ship: Also at tier 4, so long as you are aboard a ship to which you are attuned, the crew can never gain 4 levels of fatigue.
