Warlock Patron- The Lingering Shadow

Many a creature dwells within shadow and darkness that love to entice the foolish mortals to accept pacts. While Hexblade's often stem from the Shadowfell, their powers do not reflect the true power of the Negative Energy Plane. Lingering Shadow Patrons on the other hand embrace the powers of darkness and bestow them upon their loyal followers.

Eldritch Invocations

Blinding Blast Prerequisite- eldritch blast cantrip: Your eldritch blasts now carry accursed darkness or blinding light with them. The first time you hit a creature with an eldritch blast each turn you can force them to make a Constitution saving throw versus your spell save DC. On a fail the creature is blinded until the end of their next turn.

Festering Darkness: Prerequisite- 7th level: Your necrotic attacks cause the negative energy to cling to the victim, further draining their vitality. After you deal necrotic damage with a spell, the creature(s) become cursed for 1 minute. Whenever a creature cursed in this way makes an attack roll, ability check or saving throw you can use your Reaction to cause the necrosis to flair up thereby subtracting your Charisma modifier from the roll. Once you activate this ability the curse ends on the creature and it becomes immune to this feature for 24 hours.

Expanded Spell List

The Lingering Shadow 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.

Shadow Expanded Spells

Silhouette

At 1st level when you form this Pact shadows naturally cling to you granting you proficiency with Stealth checks. Additionally while in dim light or darkness, you can Hide as a Bonus action.

Cloak of Dusk

At 6th level you have become suffused purest shadow granting you advantage against effects that would frighten and you have resistance to poison and necrotic damage.

Additionally you can use a Bonus Action to coat yourself in darkness. This transformation lasts for 10 minutes and while transformed in this way you gain advantage on Stealth and Intimidation checks, you gain a fly speed of 30 feet during which you can hover and dim light or darkness within 15 feet of you becomes magical darkness, which you and creatures you choose can see through.

Night Ruler

At 10th level your familiarity with darkness deepens. You learn additional spells if you don’t already know them, as shown in the Night Ruler Spells table. These spells are always prepared and don’t count against the number of warlock spells you know.

Night Ruler Spells

You can cast each of these spells once at their base level without expending a spell slot. Once you cast a spell in this way, you can’t do so again until you finish a long rest. 

Midnight Raiment

At 14th level you can become a being not too dissimilar to your patron. While your Cloak of Dusk feature is active you become resistant to bludgeoning, piercing and slashing damage in exchange for vulnerability to radiant damage, while in darkness your speed is doubled and any spell attack you make deals an additional 1d8 necrotic damage on a hit. Additionally, when you are in darkness, as a Bonus Action you may teleport to another source of darkness you can see within 60 feet of you.
