Class Features

Level 1

 

Pact Magic

Your arcane research and the magic bestowed on you by your patron have given you facility with spells. For rules regarding Warlock Spellcasting, see Spellcasting.  

Otherwordly Patron:

 

Expanded Spell List

The Great Old One 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.

Spell Level	Spells
1st	Dissonant Whisperes, Tasha's Hideous Laughter
2nd	Detect Thoughts, Phantasmal Force
3rd	Clairvoyance, Sending
4th	Dominate Beast, Evard's Black Tentacles
5th	Dominate Person, Telekinesis

Awakened Mind

Starting at 1st level, your alien knowledge gives you the ability to touch the minds of other creatures. You can telepathically speak to any creature you can see within 30 feet of you. You don't need to share a language with the creature for it to understand your telepathic utterances, but the creature must be able to understand at least one language.  

Level 2

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.   At 2nd level, you gain two eldritch invocations of your choice. 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.   A level prerequisite in an invocation refers to warlock level, not character level. For the available invocations in Mundus, see the dedicated parts of the Feats article. You can copy these to your sheet at the Feats section of your sheet.  

Level 3

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. 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 use its reaction to make one attack of its own.
• 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. While the book is on your person, you can cast those cantrips at will. They are considered warlock spells for you, and they needn't be from the same spell list. They don't count against your number of cantrips known.
  • 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.
• Pact of the Talisman
  • Your patron gives you an amulet, a talisman that can aid the wearer when the need is great. When the wearer fails an ability check, they can add a d4 to the roll, potentially turning the roll into a success. This benefit can be used a number of times equal to your proficiency bonus, and all expended uses are restored when you finish a long rest.
  • If you lose the talisman, 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 amulet. The talisman turns to ash when you die.

 

Level 4

Ability Score Improvement

When you reach 4th level, you can increase one Ability Score of your choice by 2, or you can increase two Ability Scores of your choice by 1. Through this way, you can't increase an Ability Score beyond 20. Alternatively, you can pick a feat.  

Level 5

 

Level 6

Entropic Ward

At 6th level, you learn to magically ward yourself against attack and to turn an enemy's failed strike into good luck for yourself. When a creature makes an attack roll against you, you can use your reaction to impose disadvantage on that roll. If the attack misses you, your next attack roll against the creature has advantage if you make it before the end of your next turn.   Once you use this feature, you can't use it again until you finish a short or long rest.

Level 9

 

Level 10

Thought Shield

Starting at 10th level, your thoughts can't be read by telepathy or other means unless you allow it. You also have resistance to psychic damage, and whenever a creature deals psychic damage to you, that creature takes the same amount of damage that you do.  

Level 11

Mystic Arcanum

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.  

Level 12

Ability Score Improvement

Level 13

 

Level 14

Create Thrall

At 14th level, you gain the ability to infect a humanoid's mind with the alien magic of your patron. You can use your action to touch an incapacitated humanoid. That creature is then charmed by you until a Remove Curse spell is cast on it, the charmed condition is removed from it, or you use this feature again.   You can communicate telepathically with the charmed creature as long as the two of you are on the same plane of existence.

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.

Spellcasting

Spellcasting

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. 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 or 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 as a spellcasting focus for your warlock spells.

Subclass Options

Your patron is a mysterious entity whose nature is utterly foreign to the fabric of reality. It might come from the Far Realm, the space beyond reality, or it could be one of the elder gods known only in legends. Its motives are incomprehensible to mortals, and its knowledge so immense and ancient that even the greatest libraries pale in comparison to the vast secrets it holds. The Great Old One might be unaware of your existence or entirely indifferent to you, but the secrets you have learned allow you to draw your magic from it.   Entities of this type include Ghaunadar, called That Which Lurks; Tharizdun, the Chained God; Dendar, the Night Serpent; Zargon, the Returner; Great Cthulhu; and other unfathomable beings.   Source: Player's Handbook  

Mundus-specific

In Mundus the distinction between Clerics, Paladins and Warlocks isn't as harsh as in the D&D universe. Thus, make up a patron of your own, or check out The Pantheon to get inspired. Any powerful demon, fey, Daedra or Aedra, may serve as a Warlock patron.   For a "Great Old One" it is preferable to use a Demon Lord or such, which can be allied to either the Abyssal Lords, Infernal Accord or to neither.
