The Arcanist

Your patron is a being that has mastered the secrets of the arcane, and is capable of casting immensely powerful spells. In exchange for their power, you are sworn to them as an apprentice, familiar or as a mere tool. Most warlocks who forge such pacts are asked to collect forbidden lore or knowledge that has been lost to time for their patron, but some fulfill the role of a lackey or servant, working to further their arcane master’s agenda.

Your patron could be any powerful entity seeking powerful magic and knowledge, such as exceptionally powerful archmages, hags or liches.

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.

2nd	arcanist's magic aura, magic mouth
3rd	nondetection, lightning bolt
4th	arcane eye, private sanctum
5th	arcane hand, legend lore

Student of Magic

Starting at 1st level, your studies under your patron has made you a diligent apprentice with extensive knowledge about the world of the arcane. You gain the following features:

Subject Expert. You gain proficiency in the Arcana skill. Your proficiency bonus is doubled with this skill.

Mage’s Apprentice. You learn two cantrips from the wizard’s spell list. These cantrips count as warlock cantrips for you and do not count against your maximum number of cantrips known.

Adept Reader. You can use any spell scrolls you find, no matter if the spell is in your class’ spell list or not. Additionally, you have advantage on the ability check to cast the spell from the scroll.

Mind of the Magi

At 6th level, your patron’s arcane influence has enhanced your mind and focus. You gain the following abilities:

Master’s Excellence. Whenever you roll an Intelligence check, you can call upon your patron to aid you, granting you a bonus to the roll equal to your Charisma modifier. You can use this feature a number of times equal to your proficiency bonus per long rest.

Focused Apprentice. While you’re concentrating on a spell, you gain a bonus to any Intelligence, Wisdom or Charisma saving throws you make equal to 1d4. This bonus increases to 2d4 when you reach 14th-level.

Essential Arcanums

At 10th level, your patron bestows upon you the ability to cast fundamental wizard spells, referred to as an essential arcanum. Choose two spells of your choice from the wizard’s spell list. These spells must be of a level higher than that of a cantrip, and lower than that of a Mystic Arcanum. The spells you choose count as warlock spells for you, and you can cast each spell at their base level once per long rest without requiring material components or spell slots.

Exalted Magic

At 14th level, your patron has bestowed you with the ability to have their arcane prowess support your own. You gain the following features:

Master’s Focus. As a reaction to yourself casting a concentration spell with one of your Pact Magic or Arcanum spell slots, you can expend an additional Pact Magic spell slot to make your patron concentrate on it for you. While your patron is doing so, concentration cannot be broken on the spell and it will last for its entire duration. While this feature is active, you cannot cast a different spell that requires concentration. You can use this feature once per long rest.

Might of the Master. Whenever you expend one of your Pact Magic or Arcanum spell slots, you can choose to have your patron increase its potency, increasing the spell’s level by 1 stage. For example, what would normally be a 5th-level spell, would instead become a 6th-level spell. You can use this feature once per long rest.
