The subtle force that is Ki can be manipulated in a million different ways. Some use it to empower their unarmed strikes, weapons, or to shield their bodies from Poison and Disease. What is almost unheard of, however, is the ability to suffuse one's Innate Magic with ki. Enter the Arcane Monk. His magic comes through the strength of body, not strength of mind. Through intense training, he has learned to manipulate his ki to produce spells much akin to a sorcerer.

• At 3rd level, you learn to turn your ki into raw arcane energy granting you the ability to cast spells. You gain a spellbook and must prepare spells.

Cantrips

• At 3rd level, you know one cantrip of your choice from the wizard spell list. You learn additional wizard cantrips of your choice at higher levels, as shown in the Cantrips Known column of the Ki Casting table.

Your Spellbook

• At 3rd level, you have a spellbook containing three 1st-level wizard spells of your choice. Your spellbook is the repository of the arcane spells you know except cantrips which are fixed in your mind..

Adding New Spells

• When you find a wizard spell of 1st level or higher, you can add it to your spellbook if it is of a level which you can prepare and if you can spare the time to decipher and copy it.
• For each level of the spell, the process takes 2 hours and costs 50 GP. The cost represents material components you expend as you experiment with the spell to master it, as well as the fine inks you need to record it. Once you have spent this time and money, you can prepare the spell just like your other spells.

Replacing Your Spellbook

• You can copy a spell from your own spellbook into another book. This is just like copying a new spell into your spellbook, but faster and easier, since you understand your own notation and already know how to cast the spell. You need to spend only 1 hour and 10 GP for each level of the copied spell.

• If you lose your spellbook, you can use the same procedure to transcribe the spells that you have prepared into a new spellbook. Filling out the remainder of your spellbook requires you to find new spells to do so, as normal.

Spell Slots

• The Ki Casting table shows how many spell slots you have. The table also shows what the level of those spell slots is; all of your spell slots are the same level. To cast one of your monk spells of 1st level or higher, you must expend a spell slot. You regain all expended spell slots on a long rest.
• For example, when you are 5th level, you have three 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.

Preparing Spells

• You prepare the list of monk Spells that are available for you to cast. To do so, choose up to a number of spells from your Spellbook equal to your Intelligence modifier + your wisdom. The Spells must be of a level or lower for which you have Spell Slots.
• Your maximum pool of ki points is reduced by the number of spells you currently have prepared.
• You can change your list of prepared spells when you finish a long rest.
• Preparing a new list of Spells requires time spent studying your Spellbook and memorizing the incantations and gestures you must make to cast the spell: at least 1 minute per Spell Level for each spell on your list.
• You regain all expended spell slots when you finish a long rest.
• When you complete a short rest you can choose to clear your mind and unprepared any number of spells of your choice.

Spellcasting Ability

• Intelligence is your spellcasting ability for your monk spells. You use your Intelligence whenever a spell refers to your spellcasting ability.
• In addition, you use your Intelligence modifier and proficiency bonus for the spell save DC of a monk 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.

Ritual Casting

• You can cast a wizard spell as a ritual if that spell has the ritual tag and you have the spell in your spellbook. You don't need to have the spell prepared.

Spellcasting Focus

• You can use your fists as you arcane focus.

Arcane Arts

If an Arcane Monk casts a cantrip or spell that costs one action (ranged spells and cantrip included ranged spells ranged is reduced to 15 feet), they can deliver it with an unarmed strike. Using a spell this way costs an additional spell slot.

Also, an Arcanes Monk gains-

• Flurry of Spells

  Flurry of spells is a full round action. When doing so, they may cast any two cantrips that they know as a bonus action.

• Magical Defence 

  You can spend 1 level one or higher spell slot to cast Mage Armor as a reaction on yourself (The spell functions the same)

• Arcane Step

  As a reaction to an attacking creature, you can spend 1 level one to add +2 to your AC if the attack misses you can teleport 30 feet. 

 

Arcane Fist

• At 6th level, your practice of martial arts and study of magic grants you insight into a new style of combat that uses strikes laced with bits of ki and arcane energy woven together. When you use your Martial Arts, you can choose to use your Intelligence modifier for attack and damage rolls instead of Strength or Dexterity.
• When you gain this feature, choose one damage type from fire, lightning, cold, or thunder. When you roll damage for your monk die you can choose to have your Martial Arts deal the chosen damage type instead of bludgeoning. (Your attacks count as magical for the sake of overcoming resistances) 

Ki Empowered Spells

• At 6th level, you gain the ability to empower your spells with the mystic power of ki. You gain the following benefits when you cast a spell.
• If a spell you cast deals damage, you may add your monk die to the damage roll.
• If a spell affects an ally, roll your Martial Arts die, the affected ally gains temporary hit points equal to the number rolled. Any target affected by these temporary hit points has resistance to the type of damage of your Arcane Fist. These temporary hit points last for 1 minute.

Ki Savant

• Your ability to weave ki and arcane energy becomes so precise you can sap the energies from other creatures when you connect with their vitals. Gain Ki points equal to half your intelligence modifier rounded up (minimum 1) each time you score a critical strike.
• In addition, you also learn how to extend the reach of your ki through your spells. You may spend up to 3 ki points as you cast a spell to increase the spells effect. Each effect costs 1 ki point.
• Disabling: any creature affected by your spell must make a constitution save or be incapacitated until the start of your next turn.
• Crippling: any creature affected by your spell has disadvantage on attack rolls and ability checks for a number of rounds equal to your intelligence modifier (min 1).
• Vital Impacting: Add an additional monk die to the damage roll of the spell if it deals damage. If the spell would cause the target to make a saving throw and the target fails the saving throw by 5 or more, that creature has vulnerability to the damage type of your monk die until the end of your turn. If a creature has resistance to the damage type, the resistance and vulnerability cancel each other. If a creature is immune to the damage type, the target takes no damage from the damage type.
• Forceful: Any target affected by this spell effect is pushed 10ft in a direction you choose. If the target collides with any object they must make a dexterity saving throw or take 2d6 bludgeoning damage.
• Obscuring: Any target affected by your spell must make a Wisdom saving throw or have their passive perception reduced by 5. Additionally they have disadvantage on wisdom perception checks for 1 minute.
