Those who serve the Magnate of Starvation learn the power granted by infinite hunger, both for sustenance and for more nebulous concepts like wealth and power. As members of the shadowy organization Cornucopia, supplicants of Starvation use their knowledge and connections in the culinary world to fund their more exotic vices.
Starting when you select this tradition at 3rd level, you learn the ability to extract the life energy of your foes. When you hit a creature with an unarmed strike or a monk weapon, you may create a Consumptive Tether between you and the creature, forming a thick and shadowy black line that connects you to one another.
Your Consumptive Tether lasts for 1 minute, until you are knocked unconscious, until you are more than 30 feet away from the creature, or until you create a Consumptive Tether on a new creature. When a creature connected to you with a Consumptive Tether begins its turn, it takes Necrotic damage equal to your Wisdom modifier, and you gain temporary hit points equal to the damage.
Additionally, as a bonus action on your turn, you may spend a number of Ki points up to your proficiency bonus. When you do so, you deal 2d4 Necrotic damage to the creature for every Ki point spent, and you regain a number of hit points equal to the total damage.
At 6th level, the power of the void turns your stomach into an extradimensional space. You may store any item within your stomach that you can reasonably swallow, and such items are not digested unless you wish them to be. You may store up to 4 cubic feet or 40 pounds of material within your stomach, vomiting up all contents of your stomach if you exceed this amount. As an action, you may gag up any item stored within your stomach.
Additionally, on your turn, you may channel your hunger to instantly digest any item stored in your stomach in this capacity, gaining the effects of consuming this item with no action required. If an item has multiple uses, you consume only one use of it, and non-consumable magic items cannot be consumed in this way. You cannot use this ability if you are incapacitated.
You may use this feature a number of times equal to your Wisdom modifier, regaining all uses once you finish a long rest.
At 11th level, you gain the ability to empower yourself by consuming the strength of another. When you reduce a creature connected to you with your Consumptive Tether to 0 hit points, you may expend a hit die. When you do so, you roll the hit die and regain hit points equal to the total rolled plus your constitution modifier.
If the creature you reduced to 0 hit points has a hit die larger than your own, you may roll one of its hit die instead of your own. Similarly, if its Constitution modifier is higher than your own, you may use the creature's Constitution modifier instead of your own.
You may then select one skill the creature is proficient with, and you gain proficiency with the chosen skill. If you are already proficient with a skill you select, you gain expertise. This benefit lasts until the end of your next short or long rest, or until you use this feature to gain proficiency or expertise with another skill.
At level 17, you are able to become the manifestation of unrelenting consumption. As an action, you spend up to 10 Ki points, and select a number of creatures within 60 feet of yourself equal to the Ki points spent.
Each creature you selected must make a Constitution saving throw equal to your Ki save DC, taking 2d8 Necrotic damage on a failed save and half as much on a success. You regain hit points equal to the total damage dealt by this feature.
Once you have used this feature, you can't use it again until you finish a long rest.
