Gravewyrm

You've made a pact with a gravewyrm, a deathly dragon that favors rulers with it's blessings of knowledge and authority and eats the souls of the dead from the kingdom it's warlocks rule. Perhaps you are a member of the royal family who has been chosen to swear fealty to the deity that permits your existence? Perhaps you believe yourself a destined ruler one day, and this being is inclined to give you a chance.

Expanded Spell List

Gravewyrm lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Gravewyrm Expanded Spells

Wingblades

As an action, you can cause two membrane-free and featherless wings to sprout from your back. These wings are natural weapons with the reach and finesse properties that do not take up your hands, and deal 1d10 slashing damage on a hit. Additionally, you may use your charisma modifier for the attack and damage rolls you make with these wings. These wings last until you use a bonus action to retract them or you become incapacitated.

These wings do not confer a flight speed on their own.

If you later gain the Pact of the Blade feature, you may treat these wings as your pact weapon. If you transform a weapon into your pact weapon, you may choose to instead absorb the weapon into your wings, conferring it's magical properties unto them.  The absorption ends if the weapon stops being your pact weapon, causing the wings to lose any properties they gained from the absorption.

Jagged Tips

Starting at 6th level, you gain resistance to necrotic damage. Additionally, your Wingblades count as magical for the purposes of overcoming resistances if they did not do so already, and when you hit a creature with your Wingblades you can immediatley attempt to grapple them as a bonus action, provided you have a free hand. If you successfully grapple a target, they are pulled up to 5 feet towards you. 

Unconquerable Mind

Starting at 10th level, your patron bestows a measure of it's mental protections upon you. You are immune to scrying and to any effect that would sense your emotions, read your thoughts, or detect your location.

Additionally, no matter what you say, magic that would determine if you are telling the truth indicates you are being truthful if you so choose, and you can't be compelled to tell the truth by magic.

Royal Ascent

Starting at 14th level, you manage to mimic the arcane flight of your patron. While your Wingblades are present, you have a flight speed equal to your walking speed, as long as you are not wearing heavy armor
