The Emissary

A pact for those hungry for knowledge beyond the mortal realm, Dusk presents himself to the truly desperate and needy. Dusk presents his victims with a contract, offering knowledge and arcane power in exchange for a price to be named later. When presenting the contract, Dusk hands his victims one of his freshly plucked feathers for them to sign it with. Once signed, the feather turns red and Dusk returns the feather to his wing, signifying the presence of the deal wherever he goes. Part of Dusk's contracts allow him to pass on the favour owed by the signer to any individual he wants, often his master, Lilith.

They say the wings of Dusk whisper the deals made by his previous victims. His wings growing more red and his power growing with every deal he makes.

Those with a standing deal with Dusk are said to be able to call upon him whenever they want, however whether he responds is up to him.

 

Demon Blade

If you are attuned to an uncommon or higher dagger, short sword, longsword or glaive, that weapon becomes an Infernal weapon and deals an extra 1d4 fire damage. An infernal weapon can ignite a smouldering fire, providing a dim light for 5 ft. This fire can ignite flammable objects. You can activate this effect once per short rest and end the effect at will.

This damage increase to 2d4 at 5th level and 4d4 at 15th level.

Jump of the Winged

Once per long rest, you can use the Dimension Door spell without the need for a spell slot. If you would arrive in a place already occupied by an object or a creature, that creature or object takes 4d6 fire damage, and is pushed back 5 ft.

Infernal Awareness

If a creature tells you a lie or a half-truth, you hear a quiet sound of your choice (as arranged with Dusk). If a creature makes a deception roll, an insight roll you make has advantage.

Knowledge of the Infernal

If you are to make an Arcana, History or Nature check in relation to something infernal, you gain advantage to the roll and a +4 bonus. 

Celestial Investiture

You become physically similar to that of Dusk, gaining access to blood red wings, the ability to speak all languages and an immunity to necrotic and poison damage. You also become immune to being poisoned.

You can summon your wings once per short rest for up to 1 minute without the need for an action. These wings grant you a flying speed of 50ft.
