When you gain access to a new diabolical gift, choose one of the following. Some gifts have requirements, such as minimum diabolist level or another gift. You must meet those requirements before you choose that gift.
You can briefly borrow the potent bowels of a monster, able to digest truly disgusting fare as nourishment for yourself. You can spend 1 diaboli point as an action to consume 1 Supply that has spoiled as if it were unspoiled, gaining the usual benefits.
With 1 minute of preparation you can perform a ritual that opens up a portal within 100 feet from which a Large toe rips out to lift or support something. The toe can lift up to 1,000 pounds × your diabolist level. An object of Gargantuan size or smaller in the location where you summon the toe is perfectly raised directly upward and held there for a number of minutes equal to your diabolist level. The toe cannot be moved but it can be attacked (AC 20, 300 hit points) and it retreats early when bloodied. Once you have used this feature, you cannot use it again until you finish a long rest.
Prerequisite: Cast-Iron Stomach
You can consume a corpse to gain the benefits of 1 Supply. The corpse must be of a creature with a CR equal to at least half your diabolist level in order to gain this benefit. Consuming the corpse takes an hour; if the creature consumed is your size or smaller your consumption is total, leaving just a few telltale bloodstains. If it is larger than you, a stripped skeleton is left behind.
Your body bends and twists in ways that it shouldn’t, allowing you to traverse environments with ease. You gain an expertise die on Acrobatics and Athletics checks.
Prerequisite: Ritual Specialist
When you cast a ritual spell with a time of 10 minutes you can instead do so in 1 minute.
The workings of ritual magic are second nature to you and you are able to cast twice as many ritual spells as normal before requiring a long rest.
When a non-hostile creature within 60 feet of you fails a Strength, Dexterity, or Constitution check you can use your reaction and spend 1 diaboli point to scourge it, driving it to succeed. The creature takes 1d6 necrotic damage and adds an equal amount to the result of its ability check, potentially turning a failure into a success.
By entreating otherworldly powers with a 1 minute ritual you can make an unidentifiable and sumptuous feast of 1d4+1 Supply with all the fixings appear in an unoccupied space within 30 feet. Although filling and delicious, for the next 24 hours any creature that eats the meal has disadvantage on ability checks and saving throws against fatigue.
Once you have used this feature, you cannot use it again for 1d4 days. When you use Necromantic Touch to kill a creature with hit dice equal to or greater than your level, instead of gaining necro hit points you can recharge the use of this feature.
Preresuite: Carry Manifestation
When you use the Carry Manifestation you can expend an additional 3 diaboli points to use it on a number of willing creatures you can see equal to your diaboli level. The creatures all move in the same direction as you do and have the same fly speed, but may move a shorter distance (as little as 5 feet, or 10 feet if you take the Dash action).
