SAVY

Beginning when you choose this role as your specialty, at 1st rank, and again at 2nd, 3rd, 4th, and 5th rank, you can choose a Savy.

Chef

At 1st rank, you've taken upon yourself to feed the entire crew. You gain proficiency in cook's utensils and gain a set for yourself. You may spend an hour prepping a special meal for the crew by making a check with these tools (ability used depends on how you cook the meal and is up to the discretion of the DM). Depending on the result the crews morale will either increase or decrease by 1. This feature may only be used once a week.

Scrounge For Food

At 2nd rank, you can order the crew to spend the day fishing and scrounging an island/mainland for food and ingredients. Make a Wisdom (Survival) check modified by your crews morale score to determine if they catch anything. If the crew is successful the ship gains one "Bulk" of food and drink.

Hunt

Also at 2nd rank, you've found that its a lot cheaper to hunt your food than buy it. When you lead your crew in hunting aquatic creatures you make a Wisdom (Survival) check modified by your crews morale score.
Additionally, you have advantage on Wisdom (Animal handling) checks on aquatic creatures. Also you have advantage on Intelligence (Nature) checks on aquatic creatures.

Drink Up Me Hearties

At 3rd rank, you know that good food and rum always raises the crews spirits. You throw a four hour party on the ship, the crews morale is increased by 1, and one "Bulk" of food and drink is used up.

Experienced Chef

Also at 3rd rank, you've trained some of the other crew to aid you in the kitchen. While the crew aids you in cooking you may add their morale score to the result.
Additionally when you prepare a special meal for the crew using a rare ingredient (Sea monster, rare fish, unique herb, etc.) the morale increased or decreased is now 2.

Old Sea Bones

Also at 4th rank, you've cooked so many aquatic creatures that you've begun to memorize their anatomy and can tell your ally's where their vital spots are. When an ally that can hear you makes an attack roll against an aquatic creature you may use your reaction to give the attack advantage. You may do this after the attack is already rolled but before any outcome is determined. You may use this feature a number of times equal to your proficiency bonus and regain all uses after a long rest aboard your ship.

In Their Hearts and Belly

At 4th rank, you've cooked for the crew for a long time now and the crew appreciates that. You have advantage on Charisma (Persuasion) checks when dealing with the crew.

A Legendary Meal

people Also at 5th rank, you've mastered the craft of cooking. When you successfully prepare a special meal for the crew their morale is temporarily increased (to a max of 10) by your proficiency bonus for 8 hours.
