Warlock (Revised)

[PwrHngryTortois]

The Warlock is a really cool class with unique abilities, but a an absolute slog to play in combat unless your party short rests after every fight. Here is a link to my revised Warlock, I tried to let the warlock lean more on its pact invocations and once a day spells as opposed to spamming eldritch blast with agonizing blast (which is now locked behind 12th level tome pact, sorry!) Changes are underline in the Spoilers for the Warlock class.

I did this by extending Mystic Arcanum down to lower levels and giving you a free invocation tied to you Pact Boon at 3rd and 10th, in addition to vamping up the Invocations so that they're more utility based and not all about making eldritch blast the only spell you ever need.

• (a) a component pouch or (b) an arcane focus
• (a) a scholar's pack or (b) a dungeoneer's pack
• Leather armor, any simple weapon, and two daggers

Otherworldly Patron
At 1st level, you have struck a bargain with an otherworldly being of your choice:
• Archfey
• Celestial
• Fiend
• Great Old One
• Hexblade
• The Lurker in the Depths (Revised)
• Raven Queen (UA)
• Seeker (UA)
• Undying
Your choice grants you features at 1st level and again at 6th, 10th, and 14th level.

Pact Magic
Your arcane research and the magic bestowed on you by your patron have given you facility with spells.
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.

Mystic Arcanum
At 1st level, your patron bestows upon you a magical secret called an arcanum. Choose one 1st-level spell from the warlock spell list as this arcanum. Whenever your Warlock Spell slot increases in level, you may learn one arcanum of the corresponding level.
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.

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. Invocations you learn as part of your Pact Boon can only be replaced by invocations that have you pact boon as a requirement.
A level prerequisite in an invocation refers to warlock level, not character level.

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.
At 3rd Level you gain one invocation that requires the Pact of the Blade feature. You gain another at 10th Level.

• 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.
At 3rd Level you gain one invocation that requires the Pact of the Chain feature. You gain another at 10th Level.

• 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.
At 3rd Level you gain one invocation that requires the Pact of the Tome feature. You gain another at 10th Level.

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.

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.
