Order of the Arcane studies

Disclaimer: This subclass is heavily based on the Order of the Profane Soul subclass sharing some of its abilities however, this does have a lot of changes including allowing you to cast more powerful magic more times. If you were hoping for something completely new sorry to disappoint you but if you wanted to play a sort of wizard/blood hunter this is the subclass for you. I don't know for sure who made the subclass but I think it was mat mercer because he made the class so here is me crediting him or whoever made it.

This subclass is a mix between two classes, blood hunters and wizards. Blood hunters must learn from one of the 8 schools of magic and not any of the nonspecific schools like the war mage or the art of blade singing.

School of magic

When you reach 3rd level, You start to study magic and how to cast spells, you can choose one of the 8 main schools of magic: Abjuration, Conjuration, Divination, Enchantment, Illusion, Necromancy, Transmutation all which can be found in the Player’s Handbook

Abjuration

You have chosen Abjuration as your school of magic.

Conjuration

You have chosen Conjuration as your school of magic.

Divination

You have chosen the Divination as your school of magic.

Enchantment

You have chosen Enchantment as your school of magic.

Evocation

You have chosen Evocation as your school of magic

Illusion

You have chosen Illusion as your school of magic.

Necromancy

You have chosen Necromancy as your school of magic.

Transmutation

You have chosen Transmutation as your school of magic

Spellcasting

When you reach 3rd level, you can augment your combat techniques with the ability to cast spells. See chapter 10 of the PHB for the general rules of spellcasting and chapter 11 of the Player’s Handbook for the Warlock spell list.

Cantrips. You learn three cantrips of your choice from the wizard spell list. You learn an additional wizard cantrip of your choice at 7th level and another at 13th level.

Spell Slots. The Arcane studies Spellcasting 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 wizard 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 8th level, you have two 2nd-level spell slots. To cast the 1st-level spell magic missile, you must spend one of those slots, and you cast it as a 2nd-level spell.

Spells In Book of 1st Level and Higher. At 3rd level, you know six 1st-level spells of your choice from the wizard spell list and learn a new spell each time you level up when you. lose your spellbook or it is destroyed you can't prepare or cast any spells that you didn't already have prepared. You can make a copy of your spellbook by copying your spells into another one, it costs 25GP per level and takes 30 minutes per spell level.

The Spells Known column of the Arcane studies table shows when you how many wizard spells of your choice of 1st level and higher you should have in your spellbook. 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 11th level, for example, you can add a new wizard spell to your spellbook, which can be 1st, 2nd, or 3rd level.

When you choose a spell in this class you can't change what spells you had known unless your spellbook is destroyed, in which case you have to choose to completely restart your spellbook from the spells you had prepared to the maximum number of spells you can have in this class.

Spellcasting Ability. Intelligence is your spellcasting ability for your wizard spells, so you use your Intelligence whenever a spell refers to your spellcasting ability. Also, you use your Intelligence modifier when setting the saving throw DC for a wizard spell you cast and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus + your Intelligence modifier

Spell attack modifier = your proficiency bonus + your Intelligence modifier

Rite Focus

Beginning at 3rd level, your weapon becomes a core to link to the weave.
