The Undying Light Warlock

---

---

Overview & Creation

With a pseudodragon curled on his shoulder, a young elf in golden robes smiles warmly, weaving a magical charm into his honeyed words and bending the palace sentinel to his will.   As flames spring to life in her hands, a wizened human whispers the secret name of her demonic patron, infusing her spell with fiendish magic.   Shifting his gaze between a battered tome and the odd alignment of the stars overhead, a wild-eyed tiefling chants the mystic ritual that will open a doorway to a distant world.   Warlocks are seekers of the knowledge that lies hidden in the fabric of the multiverse. Through pacts made with mysterious beings of supernatural power, warlocks unlock magical effects both subtle and spectacular. Drawing on the ancient knowledge of beings such as fey nobles, demons, devils, hags, and alien entities of the Far Realm, warlocks piece together arcane secrets to bolster their own power.  

Sworn and Beholden

---

A warlock is defined by a pact with an otherworldly being. Sometimes the relationship between warlock and patron is like that of a cleric and a deity, though the beings that serve as patrons for warlocks are not gods. A warlock might lead a cult dedicated to a demon prince, an archdevil, or an utterly alien entity—beings not typically served by clerics. More often, though, the arrangement is similar to that between a master and an apprentice. The warlock learns and grows in power, at the cost of occasional services performed on the patron’s behalf.   The magic bestowed on a warlock ranges from minor but lasting alterations to the warlock’s being (such as the ability to see in darkness or to read any language) to access to powerful spells. Unlike bookish wizards, warlocks supplement their magic with some facility at hand-to-hand combat. They are comfortable in light armor and know how to use simple weapons.  

Delvers into Secrets

---

Warlocks are driven by an insatiable need for knowledge and power, which compels them into their pacts and shapes their lives. This thirst drives warlocks into their pacts and shapes their later careers as well.   Stories of warlocks binding themselves to fiends are widely known. But many warlocks serve patrons that are not fiendish. Sometimes a traveler in the wilds comes to a strangely beautiful tower, meets its fey lord or lady, and stumbles into a pact without being fully aware of it. And sometimes, while poring over tomes of forbidden lore, a brilliant but crazed student’s mind is opened to realities beyond the material world and to the alien beings that dwell in the outer void.   Once a pact is made, a warlock’s thirst for knowledge and power can’t be slaked with mere study and research. No one makes a pact with such a mighty patron if he or she doesn’t intend to use the power thus gained. Rather, the vast majority of warlocks spend their days in active pursuit of their goals, which typically means some kind of adventuring. Furthermore, the demands of their patrons drive warlocks toward adventure.  

Creating a Warlock

---

As you make your warlock character, spend some time thinking about your patron and the obligations that your pact imposes upon you. What led you to make the pact, and how did you make contact with your patron? Were you seduced into summoning a devil, or did you seek out the ritual that would allow you to make contact with an alien elder god? Did you search for your patron, or did your patron find and choose you? Do you chafe under the obligations of your pact or serve joyfully in anticipation of the rewards promised to you?   Work with your DM to determine how big a part your pact will play in your character’s adventuring career. Your patron’s demands might drive you into adventures, or they might consist entirely of small favors you can do between adventures.   What kind of relationship do you have with your patron? Is it friendly, antagonistic, uneasy, or romantic? How important does your patron consider you to be? What part do you play in your patron’s plans? Do you know other servants of your patron?   How does your patron communicate with you? If you have a familiar, it might occasionally speak with your patron’s voice. Some warlocks find messages from their patrons etched on trees, mingled among tea leaves, or adrift in the clouds — messages that only the warlock can see. Other warlocks converse with their patrons in dreams or waking visions, or deal only with intermediaries.  

QUICK BUILD

You can make a warlock quickly by following these suggestions. First, Charisma should be your highest ability score, followed by Constitution. Second, choose the charlatan background. Third, choose the eldritch blast and chill touch cantrips, along with the 1st-level spells charm person and witch bolt.

Class Features

Otherworldly Patron

At 1st level, you have struck a bargain with an otherworldly being of your choice: The Celestial, which is detailed at the end of the class description, or one from another source. Your choice grants you features at 1st level and again at 6th, 10th, and 14th level.  

Eldritch Invocations

In your study of occult lore, you have unearthed eldritch invocations, fragments of forbidden knowledge that imbue you with an abiding magical ability. A level prerequisite refers to your level in this class.   At 2nd level, you gain two eldritch invocations of your choice. Your invocation options are detailed at the end of the class description. When you gain certain warlock levels, you gain additional invocations of your choice, as shown in the Invocations Known column of the Warlock table.   Additionally, when you gain a level in this class, you can choose one of the invocations you know and replace it with another invocation that you could learn at that level.   If an eldritch invocation has prerequisites, you must meet them to learn it. You can learn the invocation at the same time that you meet its prerequisites. A level prerequisite refers to your level in this class.   Agonizing Blast
Prerequisite: eldritch blast cantrip   When you cast eldritch blast, add your Charisma modifier to the damage it deals on a hit.   Armor of Shadows

The spells appear in the book and don’t count against the number of spells you know. With your Book of Shadows in hand, you can cast the chosen spells as rituals. You can’t cast the spells except as rituals, unless you’ve learned them by some other means. You can also cast a warlock spell you know as a ritual if it has the ritual tag.   On your adventures, you can add other ritual spells to your Book of Shadows. When you find such a spell, you can add it to the book if the spell’s level is equal to or less than half your warlock level (rounded up) and if you can spare the time to transcribe the spell. For each level of the spell, the transcription process takes 2 hours and costs 50 gp for the rare inks needed to inscribe it.   Chains of Carceri

Pact Boon

At 3rd level, your otherworldly patron bestows a gift upon you for your loyal service. You gain one of the following features of your choice.  

Pact of the Blade

You can use your action to create a pact weapon in your empty hand. You can choose the form that this melee weapon takes each time you create it (see the Weapons section for weapon options). You are proficient with it while you wield it. This weapon counts as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.   Your pact weapon disappears if it is more than 5 feet away from you for 1 minute or more. It also disappears if you use this feature again, if you dismiss the weapon (no action required), or if you die.   You can transform one magic weapon into your pact weapon by performing a special ritual while you hold the weapon. You perform the ritual over the course of 1 hour, which can be done during a short rest. You can then dismiss the weapon, shunting it into an extradimensional space, and it appears whenever you create your pact weapon thereafter. You can’t affect an artifact or a sentient weapon in this way. The weapon ceases being your pact weapon if you die, if you perform the 1-hour ritual on a different weapon, or if you use a 1-hour ritual to break your bond to it. The weapon appears at your feet if it is in the extradimensional space when the bond breaks.  

Pact of the Chain

You learn the find familiar spell and can cast it as a ritual. The spell doesn’t count against your number of spells known.   When you cast the spell, you can choose one of the normal forms for your familiar or one of the following special forms: imp, pseudodragon, quasit, or sprite.   Additionally, when you take the Attack action, you can forgo one of your own attacks to allow your familiar to make one attack with its reaction.  

Pact of the Tome

Your patron gives you a grimoire called a Book of Shadows. When you gain this feature, choose three cantrips from any class’s spell list (the three needn’t be from the same list). While the book is on your person, you can cast those cantrips at will. They don’t count against your number of cantrips known. If they don’t appear on the warlock spell list, they are nonetheless warlock spells for you.   If you lose your Book of Shadows, you can perform a 1-hour ceremony to receive a replacement from your patron. This ceremony can be performed during a short or long rest, and it destroys the previous book. The book turns to ash when you die.  

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score above 20 using this feature.   Using the optional feats rule, you can forgo taking this feature to take a feat of your choice instead.  

Mystic Arcanum (6th level)

At 11th level, your patron bestows upon you a magical secret called an arcanum. Choose one 6th-level spell from the warlock spell list as this arcanum.   You can cast your arcanum spell once without expending a spell slot. You must finish a long rest before you can do so again.   At higher levels, you gain more warlock spells of your choice that can be cast in this way: one 7th-level spell at 13th level, one 8th-level spell at 15th level, and one 9th-level spell at 17th level. You regain all uses of your Mystic Arcanum when you finish a long rest.  

Mystic Arcanum (7th level)

At 13th level, your patron bestows upon you a magical secret called an arcanum. Choose one 7th-level spell from the warlock spell list as this arcanum.   You can cast your arcanum spell once without expending a spell slot. You must finish a long rest before you can do so again.   At higher levels, you gain more warlock spells of your choice that can be cast in this way: one 8th-level spell at 15th level, and one 9th-level spell at 17th level. You regain all uses of your Mystic Arcanum when you finish a long rest.  

Mystic Arcanum (8th level)

At 15th level, your patron bestows upon you a magical secret called an arcanum. Choose one 8th-level spell from the warlock spell list as this arcanum.   You can cast your arcanum spell once without expending a spell slot. You must finish a long rest before you can do so again.   At 17th level, you gain a 9th-level warlock spell of your choice that can be cast in this way. You regain all uses of your Mystic Arcanum when you finish a long rest.  

Mystic Arcanum (9th level)

At 17th level, your patron bestows upon you a magical secret called an arcanum. Choose one 9th-level spell from the warlock spell list as this arcanum.   You can cast your arcanum spell once without expending a spell slot. You must finish a long rest before you can do so again.   You regain all uses of your Mystic Arcanum when you finish a long rest.  

Eldritch Master

At 20th level, you can draw on your inner reserve of mystical power while entreating your patron to regain expended spell slots. You can spend 1 minute entreating your patron for aid to regain all your expended spell slots from your Pact Magic feature. Once you regain spell slots with this feature, you must finish a long rest before you can do so again.

You start with the following equipment, in addition to the equipment granted by your background:

• (a) a light crossbow and 20 bolts or (b) any simple weapon

Spellcasting

Pact Magic

Your arcane research and the magic bestowed on you by your patron have given you facility with spells. See Spells Rules for the general rules of spellcasting and the Spells Listing for the warlock spell list.  

Cantrips

You know two cantrips of your choice from the warlock spell list. You learn additional warlock cantrips of your choice at higher levels, as shown in the Cantrips Known column of the Warlock table.  

Spell Slots

The Warlock table shows how many spell slots you have to cast your warlock spells of 1st through 5th level. The table also shows what the level of those slots is; all of your spell slots are the same level. To cast one of your warlock spells of 1st level or higher, you must expend a spell slot. You regain all expended spell slots when you finish a short or long rest.   For example, when you are 5th level, you have two 3rd-level spell slots. To cast the 1st-level spell witch bolt, you must spend one of those slots, and you cast it as a 3rd-level spell.  

Spells Known of 1st Level and Higher

At 1st level, you know two 1st-level spells of your choice from the warlock spell list.   The Spells Known column of the Warlock table shows when you learn more warlock spells of your choice of 1st level and higher. A spell you choose must be of a level no higher than what’s shown in the table’s Slot Level column for your level. When you reach 6th level, for example, you learn a new warlock spell, which can be 1st, 2nd, or 3rd level.   Additionally, when you gain a level in this class, you can choose one of the warlock spells you know and replace it with another spell from the warlock spell list, which also must be of a level for which you have spell slots.  

Spellcasting Ability

Charisma is your spellcasting ability for your warlock spells, so you use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for a warlock spell you cast and when making an attack roll with one.   Spell save DC = 8 + your proficiency bonus + your Charisma modifier   Spell attack modifier = your proficiency bonus + your Charisma modifier  

Spellcasting Focus

You can use an arcane focus (see the Adventuring Gear section) as a spellcasting focus for your warlock spells.

Subclass Options

The Undying Light

---

Your patron is not a specific entity, but the energy that radiates from the Positive Plane. Your pact allows you to experience the barest touch of the raw stuff of life that powers the multiverse. Anything more, and you would be instantly incinerated by it's energy.  

Contact with the Positive Plane causes subtle changes to your behavior and beliefs. You are driven to bring light to dark places, to annihilate undead creatures, and to protect all living things. At the same time, you crave the light and find total darkness a suffocating experience akin to drowning.  

Undying Light Features

Warlock Level	Feature
1st	Expanded Spell List, Bonus Cantrips, Radiant Soul
6th	Searing Vengeance
10th	Radiant Resilience
14th	Healing Light

 

Expanded Spell List

The Celestial 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.  

Celestial Expanded Spells

Spell Level	Spells
1st	burning hands
2nd	flaming sphere
3rd	daylight
4th	fire shield
5th	flame strike

 

Bonus Cantrips

At 1st level, you learn the light and sacred flame cantrips. They count as warlock cantrips for you, but they don’t count against your number of cantrips known.

Radiant Soul

Starting at 1st level, your link to the Celestial allows you to serve as a conduit for radiant energy. You have resistance to radiant damage, and when you cast a spell that deals radiant or fire damage, you can add your Charisma modifier to one radiant or fire damage roll of that spell against one of its targets.

Searing Vengeance

Starting at 6th level, the radiant energy you channel allows you to resist death. When you have to make a death saving throw at the start of your turn, you can instead spring back to your feet with a burst of radiant energy. You regain hit points equal to half your hit point maximum, and then you stand up if you so choose. Each creature of your choice that is within 30 feet of you takes radiant damage equal to 2d8 + your Charisma modifier, and it is blinded until the end of the current turn.  

Radiant Resistance

Starting at 10th level, you gain temporary hit points whenever you finish a long or short rest. These temporary hit points equal your warlock level + your Charisma modifier. Additionally, choose up to five creatures you can see at the end of your rest. Those creatures gain temporary hit points equal to half your warlock level + your Charisma modifier.    

Healing Light

At 14th level, you gain the ability to channel the Undying Light to heal yourself and other creatures. As a bonus action, you can touch a creature and heal it. With each touch, a creature regains from 1d6 to 5d6 hit points (your choice). You have a total pool of 15d6 you can expend. Subtract the dice you use with each touch from that total.
