The Arcane

The Arcane is a powerful magical being, an expert of all things arcane, only the most prolific and talented archmages, wizards, and magicians. Patrons such as this are not limited to humanoids, as any creature with a powerful enough understanding of the arcane workings of the Weave can provide a worthy acolyte with gifts of magical capacity.

Different from apprenticeship, warlocks of these magical patrons do not learn their magic from their patrons, but rather are somehow granted the use it. This could be through magically implanted memories, bioarcane experimentation, or any other kind of magical method the Arcane chooses to bless or curse their warlock followers with. Warlocks of this sort often become unparalleled spellslingers, performing any sort of task or errand their magical patrons require of them.

Examples of the Arcane include Aganazzar, Bigby, Drawmij, Evard, Leomund, Melf, Mordenkainen, Nystul, Otiluke, Otto, Rary, Snilloc, Tasha, Tenser, and any other magicians powerful enough to remember the name of.

2nd	levitate, Nystul's magic aura
3rd	lightning bolt, magic circle
4th	Otiluke's resilient sphere, polymorph
5th	creation, teleportation circle

Mage Minded

Starting at 1st level, the magic of your patron's powerful influence grants you knowledge of the workings of the arcane. You gain proficiency in the Arcana skill and learn one cantrip of your choice from the wizard spell list. This counts as a Warlock spell for you and does not count against your spells known.

Also, you gain one additional warlock spell slot for your Pact Magic feature.

Extended Incantation

Starting at 6th level, your patron’s adeptness with the use of spellcraft has given you the ability to overclock your own spells. When expending a warlock spell slot by casting a spell that has a duration of Instantaneous and has a casting time of 1 action, you can choose to extend its use. When a spell is extended, its duration becomes 1 minute and requires concentration to maintain. During the duration of the extended spell, you can cast it again during your turn as an action without expending a spell slot.

Once you use this feature, you can’t use it again until you finish a long rest.

Spellslinger

Starting at 10th level, the finesse with which you cast your spells has become invaluable. Whenever you cast a warlock spell as an action, you can use a bonus action to cast a warlock cantrip that has a casting time of one action. You can cast a cantrip using this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Additionally, you learn two spells of 3rd level or lower from the wizard spell list, which count as warlock spells for you, but don't count against the number of spells you know.

Master Arcanist

Starting at 14th level, your arcane mastery nearly rivals your patron's. The Slot Level of your warlock spells increases to 6th level rather than 5th level. You also learn one 6th-level spell of your choice from the warlock or wizard spell lists, which counts as a warlock spell for you, but don't count against the number of spells you know. 

Additionally, you can gain advantage on saving throws against spells and other magical effects until the beginning of your next turn as a reaction.
