The Necrocomicon

As a result of your studies on magic and ancient spell books, you discovered a ritual. This ritual was used to transform an ordinary spell book into a special Grimoire called a "Necronomicon" that merged with the soul of its user. And you were either brave or mad enough to use this Grimoire.

Awakened Necronomicon

Along with the spells contained in, your spellbook has been transformed into a Necrocomicon. This has given you the following features.

 

• If your Necrocomicon is destroyed or lost, you can regenerate it with 1 hour of meditation. This action can be done during Short Rest. After this action is performed, the Necronomicon you previously created will be destroyed.

• You don't need any materials for copying spells into your Necrocomicon. 

•You can use Necrocomicon as Arcane Focus. •Necronomicon can glide within 5 feet of you. (Using it this way will not affect your use as Arcane Focus, you can use it as Arcane Focus even if it floats.)

 • The time you must spend to copy a spell into your Necronomicon equals 2 minutes per spell level.

 • The Necrocomicon is a reflection of your soul. Therefore, it grants 1 extra spell per each level. This spell can belong to any class.

Apprentice of Necronomicon

The Necrocomicon's power grew with you and granted you the following blessings.

 

• The Necrocomicon's aura surrounds and protects you as you hold it. Your Armor Class increased by your Intelligence Modifier. (If it's in floating form, this increase is half of the Intelligence Modifier, rounded down.)

• Your Spell Attack and Spell Save DC is increased by +1.

This increase becomes +2 at level 10 and +3 at level 14.

• Once per day, you can cause a spell equal to your Proficiency Bonus to deal maximum damage or healing. If you cast a spell this way, you can only cast Cantrip for 1d4 rounds.

Journeyman of Necronomicon

With the Necronomicon you can now achieve things that are impossible for most mages.

 

• You can now use 2 concentration spells at the same time. The dice you need to roll to protect these spells must be rolled with disadvantage. Likewise, when using this ability (with the Spell Casting action), you can only use Cantrip.

Master of Necronomicon

You have finally mastered the most powerful grimoire to ever exist. Necronomicon now gives you everything it can and turns you into an invincible mage.

 

• After each Long Rest, you can roll 1d10-1 and cast a spell of the level of the number that comes up once that day without spending a Spell Slot. If the result is 0, you cannot cast any of your spells with this method until the next Long Rest. 

• You no longer age and are immune to aging effects. • You are immune to Charmed, Frightened, and Possessed. 

• Your 7th Level Spell Slot(s) increased by one. At level 16, the 8th Level Spell Slot(s) increases, and at level 18, the 9th Level Spell Slot(s) increases by one.
