Pact of the Blade

Gain a pact weapon. You also gain proficiency in medium armor and shields.

You can use your action to summon the pact weapon to your empty hand. You can choose the form that this melee weapon takes each time you summon it (see the Weapons section for weapon options). It counts as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

You can perform the somatic components of your Eldritch Blast or warlock spells with the same hand you are using to hold this weapon. If you do so for Eldritch Blast, it becomes a melee spell attack with a range of 10 feet, and on a hit, the target takes 1d12 force damage.

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 summon 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

Gain a familiar as if you had cast the find familiar spell. You can choose one of the normal forms for your familiar or one of the following special forms: imp, pseudodragon, quasit, or sprite. Whatever your choice, the familiar's hit point maximum is increased by an amount equal to your warlock level and its AC is equal to your warlock spell save DC.

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

Gain a grimoire called the Book of Shadows. When you gain this feature, choose a number of cantrips from any class’s spell list equal to your proficiency (they needn’t be from the same list). While the book is on your person, you can cast them at will. You can change these additional cantrips when you finish a long rest.

In addition, learn a spell from the wizard spell list. A spell you learn needn't be of a tier for which you have spell slots. You learn an additional spell from the same list each time you gain a level in this class.

The chosen spells count as warlock spells known for you but don't count against the number of warlock spells and cantrips you know.

These spells don’t count against your number of cantrips or spells known. If they don’t appear on the warlock spell list, they are nonetheless warlock spells for you.

When your Spellcasting feature lets you learn a sorcerer cantrip or a sorcerer spell of 1st level or higher, you can choose the new spell from the cleric spell list or the sorcerer spell list. You must otherwise obey all the restrictions for selecting the spell, and it becomes a sorcerer spell for you. The chosen spells don't count against the number of warlock spells you know.

Pact of the Talisman

Gain 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, and all expended uses are restored when you finish a long rest.

In addition, when the wearer of your talisman fails a saving throw, you can use your reaction to add a bonus to the roll equal to 1d4 + half your warlock level, potentially turning the save into a success. If it does, the talisman is destroyed, crumbling into ash.
