The Arcanist

You have made a pact with a being of immense magical knowledge—a master of the arcane whose power transcends mortal understanding. This patron might be a legendary archmage, a lich guarding forbidden lore, or a mysterious entity woven from raw magic. In return for your power, you serve as an apprentice, a devoted scholar, or a mere tool for your patron's schemes. Many Arcanist warlocks recover lost tomes, uncover forbidden spells, or advance their patron’s inscrutable goals in even more eccentric ways.

Expanded Spell List

The Arcanist 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.

Arcanist Expanded Spells

Spell Level	Spells
1st	magic missile, identify
2nd	see invisibility, detect thoughts
3rd	nondetection, lightning bolt
4th	arcane eye, resilient sphere
5th	arcane hand, legend lore

Student of Magic

Beginning at 1st level, you possess extensive knowledge of the arcane. You gain proficiency in the Intelligence (Arcana) skill. Your proficiency bonus is doubled for any ability check you make that uses this proficiency. In addition, you learn one cantrip of your choice from the wizard spell list. This cantrip counts as a warlock cantrip for you and does not count against your maximum number of cantrips known.

Magical Resilience

Also at 1st level, magic invigorates you. Whenever you cast a warlock spell using a Pact Magic spell slot, you gain temporary hit points equal to the spell’s level plus your Charisma modifier.

Essential Arcanum

At 6th level, you can borrow knowledge from your patron’s personal repertoire. Choose three spells of your choice from the wizard spell list: one of 1st level, one of 2nd level and one of 3rd level. The spells you choose count as warlock spells for you and do not count against your total number of spells known. You can cast one of these spells at its base level once per long rest, without expending a spell slot. You can also cast these spells using your Pact Magic spell slots.

Fortified Mind

At 10th level, the eldritch magic you wield reinforces your mind. While you're concentrating on a warlock spell, you have advantage on Intelligence, Wisdom and Charisma saving throws.

Exalted Arcana

At 14th level, you can call upon your patron's magical power to enhance your own.You gain an additional Pact Magic spell slot that is more potent than your other spell slots. When you cast a warlock spell using this slot, the spell's level is increased by one. Once you've spent this spell slot, you must finish a long rest to regain it.
