Extra Warlock Invocation Options

Arcane Fury of the Familiar

Prerequisite: 10th level, Pact of the Chain feature

When you cast a spell of with a range of 120 feet or less, your familiar can deliver the spell as if it had cast the spell. Your familiar must be within 100 feet of you, and it must use its reaction to deliver the spell when you cast it. If the spell requires an attack roll, you use your attack modifier for the roll.

If the spell deals damage and is higher than first level, your familiar must make a constitution saving throw after casting the spell. If it fails the saving throw it takes 1d4 force damage for each level of the spell above 1st.

Beastly Shape-Change

Prerequisite: 5th level, Pact of the Chain feature

For five minutes, you can have your familiar take the form of any beast of size large or smaller with a challenge rating of 1 or lower. The familiar has the statistics and can use any of the actions of the chosen form for the duration of the ten minutes.

In combat, when your familiar transform, it assumes the beast form’s hit points and Hit Dice. When it reverts to its normal form, it returns to the number of hit points it had before it transformed. However, if it reverts as a result of dropping to 0 hit points, any excess damage carries over to its normal form. For example, if it takes 10 damage in its beast form and it has only 1 hit point left, it reverts and take 9 damage. As long as the excess damage doesn’t reduce its normal form to 0 hit points, it does not disappear.

You must finish a long rest before you can use this invocation on your familiar again.

Bringer of Dreams and Nightmares

Prerequisite: 9th level

You can cast Dream once without expending a spell slot. You can't do so again until you finish a long rest.

Consumption of the Soul

Prerequisite: 5th level, Pact of the Blade feature

When you reduce a creature to 0 hit points, as a result of an attack with your pact weapon or hexblade weapon, you can use you reaction to regain hit points equal to your warlock level and have advantage on the next attack with the pact weapon.

Once you use this ability, you can't do so again until you finish a short or long rest.

Dreadful Harbinger of Darkness

Prerequisite: 7th level

You can cast Darkness at will without expending a spell slot.

Emerge from the Shadows

Prerequisite: 3rd level

You can cast Misty Step once without expending a spell slot. You can't do so again until you finish a long rest.

Enchanting Fog

When you cast an enchantment type spell on a creature, if the spell says the creature realizes that you used magic on it when the spell ends the creature instead must make a wisdom saving throw. If it fails the saving throw, it's unaware any magic or spell was placed on it.

Forgotten Spellbook of the Mad

Prerequisite: 10th level, Pact of the Tome feature

Your Book of Shadows can now learn almost any spell in much the same way a wizard's spellbook can. Choose one 1st level spell, one 2nd level spell, and one 3rd level spell from any class’s spell list (the three needn’t be from the same list). Those spells are then transcribed in the book and you always have them known while you have the book, but they don’t count against your number of spells known. If they don’t appear on the warlock spell list, they are nonetheless warlock spells for you.

On your adventures, you can add other 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.

If it is a warlock spell, the gold and time you must spend to copy the spell into your spellbook is halved.

Gift of Second Life

When you are reduced to 0 hit points but not killed outright, you can use you reaction to regain 1 d8 hit points and stand back up. You can’t use this feature again until you finish a long rest.

Invader of the Mind

Prerequisite: 7th level

You can cast Detect Thoughts at will without expending a spell slot.
