The Shadow

The Shadow subclass for Warlocks delves into the obscure realms of the Shadowfell, forging a bond with the darkness that shrouds reality. Through a pact with shadowy entities, you glean the essence of fallen adversaries as shadow echoes, while also mastering the art of summoning a shadow spirit, empowered by the very echoes you collect.

Expanded Spell List

The 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.

Fiend Expanded Spells

Spell Level	Spells
1st	disguise self, sleep
2nd	pass without trace, mirror image
3rd	nondetection, blink
4th	greater invisibility, freedom of movement
5th	seeming, modify memory

Shadow Pact

At 1st level, your communion with the Shadowfell enables you to seize the essence of fallen creatures as shadow echoes. Whenever a creature within 60 feet of you dies, a shadow echo is automatically captured if you have space available. If that creature was reduced to 0 hit points by you, you instead gain a number of shadow echoes equal to that creature’s CR.  You can maintain a maximum number of shadow echoes equal to your Warlock level.

Shadow Spirit

At 1st level, you gain the ability to summon a shadow spirit, an ethereal entity bound to your will. As an action, you can summon the shadow spirit, manifesting it in an unoccupied space within 30 feet of you. The spirit is an ally to you and your companions. It shares your initiative count in combat and obeys verbal commands without requiring an action. If no commands are issued, it takes the Dodge action and moves to avoid danger. Whenever you summon the shadow spirit you can spend any number of shadow echoes to enhance its abilities as shown in the shadow spirit statblock.
You can summon the shadow spirit a number of times equal to your proficiency bonus per long rest. The spirit disappears if it is reduced to 0 hit points, or after 10 minutes.

Shadow Infusion

At 6th level, you gain the ability to infuse yourself or an ally with the power of shadows. As a bonus action, you can consume any number of shadow echoes, drawing upon their essence. You, or an ally within 60 feet, gain a number of temporary hit points equal to 5 per two shadow echoes consumed. Whenever you use this ability all previous temporary hit points gained from it are lost.

Shadow Harvest

At 10th level, you unlock the ability to harness the power of shadows from the Shadowfell. As a bonus action, you beseech your patron to provide you with shadows from the depths of the Shadowfell. You gain a number of shadow echoes equal to half your level. These shadow echoes last until the end of your next turn or they are lost as the shadows cling back to the Shadowfell. You can use this ability once per long rest, or twice if your level in this class is 15 or higher.

Echoes of Your Enemies

At 14th level, you gain the ability to preserve the templates of defeated creatures to use them in the future, maintaining a maximum of five creature templates at a time. Upon the demise of a creature within 60 feet of you, its template is automatically acquired if you have space available. Alternatively, you can choose to switch a template you had for the new one.
As an action, you can spend a use of your Shadow Spirit feature to summon one of these preserved creatures spending an amount of shadow echoes equal to its CR. Channeling their essence into a spectral form, the echo manifests in an unoccupied space within 30 feet of you. It is an ally to you and your companions, sharing your initiative count in combat and obeying verbal commands without requiring an action. If no commands are issued, it takes the Dodge action and moves to avoid danger.

You cannot have an echo of an enemy and the shadow spirit summoned simultaneously; only one can be summoned at any given time. The echo disappears if it is reduced to 0 hit points, or after 10 minutes.
