Sharkbait's Compendium of Stuff: Warlock Flavored

Eldritch Invocations

At 2nd level, a warlock gains the Eldritch Invocations feature. Here are a whole buncha options for them.

Abyssal Rebuke

Prerequisite: Hellish Rebuke

The flames summoned by your Hellish Rebuke spell are tainted by fumes from the Abyss. When you cast Hellish Rebuke, the creature must also make a Constitution saving throw against your spell save DC. On a failed save, the creature becomes poisoned for 1 minute. Creatures affected by the poison can make another Constitution saving throw at the end of each of their turns. On a success, the spell ends.

Betrayal of Hollow’s Heart

Prerequisite: 5th level, Fiend Patron, Counterspell

Your Counterspell causes a cruel feedback of hellfire against the caster. When you successfully counter a spell with Counterspell, the caster of the countered spell takes 1d6 fire damage per half level of the spell countered, rounded down (to a minimum of 1).

Embrace of Auril

Prerequisite: 12th level, Archfey Patron

Your skin is freezing cold, coating objects and creatures in frost. As long as you still have a warlock spell slot available, you gain resistance to cold or fire damage (your choice whenever you finish a short or long rest).

Benefactor's Gaze

Prerequisite: Pact of the Tome

A new page appears in your Book of Shadows. With your permission, a creature can use its action to write its name on that page, which can contain a number of names equal to your Charisma modifier (minimum of 1).

Once per day, you can use your Book of Shadows to watch upon on a creature who has written their name. You can concentrate for up to 1 hour using this object as a focus and an open page of your Book of Shadows. Everything that the target creature says during this time is magically transcribed into the book. Distance is of no consequence but if the creature is on another plane of existence the ability has a 25% chance of failure.

As an action, you can magically erase a name on the page by touching the name on it.

Grace of Sarula Iliene

Prerequisite: Archfey Patron

You have the nimble grace of a Nixie while submerged in water. You have a swim speed equal to your movement speed and can breathe underwater. You add your Charisma modifier to Stealth skill checks while submerged in water or while in the rain.

Graz’zt’s Realm

Prerequisite: Fiend Patron

Once per day, you can use your action to cause the area in a 100 ft. radius of you to become reflective and mirrorlike. Creatures have disadvantage on Stealth checks made in the area unless they are invisible. This ability lasts for 10 minutes.

Strengthen the Connection

Prerequisite: Pact of the Chain

You can spend a warlock spell slot once per short rest to grant your familiar a bonus to their attack rolls, damage rolls, and saving throws equal to your Charisma modifier for 1 hour.

Limbs of Relkath

Prerequisite: 7th level, Archfey Patron

Once per day, you can turn into a 60 ft. tall oak tree over the course of 3 rounds using your concentration. You can stay in this form for up to 8 hours but cannot speak, cast spells, move, or do anything that a tree couldn’t normally do. You can dismiss this form as a bonus action. As a tree, you have 60 hit points and immunity to piercing and bludgeoning damage unless 20 or more such damage is dealt from a single attack. You revert to your normal form and original hit points when the tree is reduced to 0 hit points.

Neifon’s Vampiric Swarm

Prerequisite: 3rd level, Undying Patron, Cloud of Daggers

When you cast Cloud of Daggers, you instead summon a cloud of spectral bats in the spell’s area. The spell deals necrotic damage instead of slashing and you gain an amount of life equal to half the damage it deals whenever it deals damage. Once you have used this invocation, you can't use it again until you finish a short or long rest.

Paranoia of the Patient One

Prerequisite: 7th level, Great Old One Patron

You can expend a warlock spell slot and your action once per day to target three creatures you can see within 120 ft. Each creature can make a Wisdom saving throw against your spell save DC. On a failed save, the creature becomes frightened of each other targeted creature for 1 minute. Creatures can make a new save at the end of each of their turns, ending the effect on a successful save. If you spent a spell slot of 5th or higher, you can choose an additional creature for each spell slot above 5th.

Rennbuu’s Whims

A number of times each day equal to your CHA modifier, you can change the colors of a creature or an object of Huge size or less. The color change lasts for 24 hours.

Servants of Vanity

Prerequisite: Unseen Servant

When you cast Unseen Servant with a warlock spell slot, you summon an additional number of servants equal to half your CHA modifier, rounded up.

Spores of Zuggtmoy

Prerequisite: Fiend Patron

You can cast Fog Cloud once per day using a warlock spell slot. When you do, creatures within the spell’s area when it was cast or who pass through the area must make a Constitution saving throw against you spell save DC. Creatures that fail become poisoned for 1 minute after leaving the cloud. Affected creatures can repeat the saving throw at the end of each of their turns, ending the condition on themselves on a success.

Winter’s Hex

Prerequisite: 5th level, hex spell or a warlock feature that curses

Your curses envelop creatures like a blizzard. A the target cursed by your hex spell or by a warlock feature of yours, such as Hexblade's Curse or Sign of Ill Omen, has their movement speed reduced by 10 while cursed.

Impactful Curse

Prerequisite: 5th level, hex spell or a warlock feature that curses

As a bonus action, you can attempt to shove a creature that is affected by your hex spell or by a warlock feature of yours, such as Hexblade’s Curse or Sign of Ill Omen, by blasting them with a wave of eldritch force. When attempting to shove a creature with this ability, you make a Charisma check with proficiency instead of an Strength (Athletics) check.

To use this invocation, you must be able to see the cursed target and it must be within 30 feet of you.

Eldritch Armory

Prerequisite: Pact of the Blade

You can create second pact weapon and/or bind a second weapon as your pact weapon, and can summon both as a single action.

Shield of Atropis

Prerequisite: Pact of the Blade

You can create a Pact Shield in addition to your pact weapon, which appears strapped to your waiting arm. You are proficient with this shield, and you can summon both your shield and your weapon as a single action. Your Pact Shield 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 shield (no action required), or if you die.

You can transform one magical shield into your pact shield by performing a special ritual while holding the shield. You perform the ritual over the course of 1 hour, which can be done during a short rest. You can then dismiss the shield, shunting it into an extradimensional space, and it appears whenever you create your pact shield thereafter. You can’t affect an artifact in this way. The shield ceases being your pact shield if you die, if you perform the 1-hour ritual on a different shield, or if you use a 1-hour ritual to break your bond to it. The shield appears at your feet if it is in the extradimensional space when the bond breaks.

Pages of Infinite Madness

Prerequisite: 12th level, Pact of the Tome

When you gain this invocation, choose two spells of fifth level or lower from the sorcerer and wizard spell list (the two needn't be from the same list). While the book is on your person, you can cast those spells as warlock spells. Once you take this invocation, it cannot be replaced when you gain a level in the warlock class.

Shadow Warrior

Prerequisite: 5th level

You learn the shadow blade spell; this spells does not count against your total number of spells known. When you make an attack with shadow blade, you can use your Charisma modifier for the attack and damage rolls.

When you cast shadow blade, you can choose to give the weapon the two-handed property; if you do so, the damage dice of the weapon become d10s. Once you use this invocation, you can't use it again until you finish a long rest.

Eyes of the Great Mother

Prerequisite: 5th level, Great Old One Patron

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.
