Base Class: Monk
Warriors of the Mystic Arts wield magic to supplement their martial skill. They harness their supernatural focus to enhance their magical and physical abilities.
Mystic Focus
You keep your magical power and martial focus in perfect balance, allowing you to convert spell slots into Focus Points, or convert Focus Points into spell slots.
Converting Spell Slots to Focus Points. You can expend a spell slot to regain a number of expended Focus Points equal to the slot’s level (no action required).
Recovering Spell Slots. As a Bonus Action, you can transform unexpended Focus Points to recover one expended spell slot. The Recovering Spell Slots table shows the cost of recovering a spell slot of a given level, and it lists the minimum Monk level you must be to recover a slot. You can recover a spell slot no higher than level 4.

Mystic Fighting Style
When you take the Attack action on your turn, you can replace one of the attacks with a casting of one of your Sorcerer cantrips that has a casting time of an action.
Centered Focus
Whenever you expend a Focus Point to use Flurry of Blows, Patient Defense, or Step of the Wind, you have Advantage on any saving throw you make to maintain Concentration until the start of your next turn.
Improved Mystic Fighting Style
When you take the Attack action on your turn, you can replace two of the attacks with a casting of one of your level 1 or 2 Sorcerer spells that has a casting time of an action.
Spellcasting
You have learned to cast spells. See the Player’s Handbook for the rules on spellcasting. The information below details how you use those rules as a Warrior of the Mystic Arts.
Cantrips. You know two cantrips of your choice from the Sorcerer spell list. Blade Ward and Thunderclap are recommended. Whenever you gain a Monk level, you can replace one of these cantrips with another cantrip of your choice from the Sorcerer spell list.
When you reach Monk level 10, you learn another Sorcerer cantrip of your choice.
Spell Slots. The Warrior of the Mystic Arts Spellcasting table shows how many spell slots you have to cast your level 1+ spells. You regain all expended slots when you finish a Long Rest.
Prepared Spells of Level 1+. You prepare the list of level 1+ spells that are available for you to cast with this feature. To start, choose three level 1 spells from the Sorcerer spell list. Jump, Magic Missile, and Shield are recommended.
The number of spells on your list increases as you gain Monk levels, as shown in the Prepared Spells column of the Warrior of the Mystic Arts Spellcasting table. Whenever that number increases, choose additional spells from the Sorcerer spell list until the number of spells on your list matches the number on the table. The chosen spells must be of a level for which you have spell slots. For example, if you’re a level 7 Monk, your list of prepared spells can include five Sorcerer spells of levels 1 and 2 in any combination.
Changing Your Prepared Spells. Whenever you gain a Monk level, you can replace one spell on your list with another Sorcerer spell for which you have spell slots.
Spellcasting Ability. Wisdom is your spellcasting ability for your Sorcerer spells. Spellcasting Focus. You can use an Arcane Focus as a Spellcasting Focus for your Sorcerer spells.
Multiclassing. If you multiclass and have the Spellcasting feature from more than one class, add one third of your Monk levels (round down) to determine your available spell slots.

Posted Feb 13, 2026I made a video about all of the decisions I made to make all of the subclasses in the UA
https://youtu.be/s4YmEa1J8g0
It's the first one I look at and I explain how it works. The audio is a bit tinny, but the information is there for anyone who wants it. You have to manually create a feature called "spellcasting" then make sure that the spellcasting type options are selected.

Posted Feb 12, 2026How did you manage to add the spellcasting feature into a homebrew subclass?

Posted Jan 17, 2026the other subclasses had problems trying to add from the UA, but I was able to create them all in the private homebrew if you have questions on how I did it. If more people could get to them, I'm sure there'd be more playtesting. I'd also like a "your mom" monster to fight against in an arena so we can have a baseline of how these things perform.
