Overview:

Adaptation of LaserLlama's Alternate Monk and Alternate Monk: Expanded homebrews into BG3

Attempts to balance between the homebrew and vanilla monk implementation as best as possible alongside what was actually feasible to implement. I recommend reading the original homebrew to see a more comprehensive explanation of the class mechanics.

There is an article explaining the deviations from the source material in this mod.

Currently Adds 11 Subclasses, Changes the 3 Vanilla Subclasses and adds 30 Techniques.

Also adds Unarmed Attack (can be used whilst melee weapon is equipped) and Decoupled Flurry of Blows to all subclasses.

Standalone versions of most of the subclasses are linked in the titles of each class.

Techniques
Adds 30 Total Techniques, which work similarly to Battlemaster Maneuvers to enhance the monk's versatility and choices in and out of combat. They can be chosen at certain levels and you have a limited total amount (a table is available in the pictures, or written below in the Base Class synopsis). A brief synopsis for each technique is below:

The DC for these techniques is 8 + Proficiency Bonus + Wisdom Modifier. You can replace a learned technique with a different one each time you level up (With the exception of Wu Jen Monks).

As of v5.0.0 passive techniques (marked with *) are automatically given when selected in the Techniques menu. When you level up a 2-minute timer is started, then the passive techniques chosen are assigned to you. If this fails for any reason you can add them by initiating a pickpocket with anyone (such as Withers).

Installation:

Compatibility:

Incompatible with ANY monk mods changing Monk class progressions. Most commonly feat mods. Subclasses can likely be merged to run however some core monk abilities (Such as Ki Adept) may not function correctly as they are hardcoded to specific spells/abilities. This mod also overrides some vanilla monk features & attacks.

UnlockLevelCurve 13-20 is compatible with the core mod, however, it overrides the Martial Arts die formula from the core, so load the core after UnlockLevelCurve

Changes the following items:
Drakethroat Glaive to allow Rising Dragon breath weapons
Corellons Grace to work with Radiance's Radiant Bolts

Patches Available for:
5e Spells
Level 13-20 / UnlockLevelCurve Patch (Check Articles for Changes & Supported Subclasses)
Hiding Dragon Scales for Rising Dragon
Draconic Bloodline Dialogue options for Rising Dragon
Level 2 Feat
Feat Every Level
Choosing a Deity
Musical Instrument Proficiency

Known Bugs / Shortfalls:

• The DC shown at the spell/technique selection/character level up screen is wrong as it uses the vanilla DC calculation
• Wu Jen Empowered Unarmed Strikes show incorrect Bludgeoning damage in the tooltips
• Disabling Strikes container spells sometimes collapse into subcontainers
• Tavern brawler causes the extra damage done to be bludgeoning (Unavoidable - hardcoded by Larian)
  

Future Plans:

• Possibly add techniques & Subclasses from Alternate Monk:Expanded
