Off the Wagon
Meditating to regain your ki points can now include things such as playing cards, drinking ale, smoking leafy matter of various types, or other relaxing activities that reset the stress of all that punching.

How Outcasts Come to Be
How a monk becomes an Outcast can vary - maybe they only ever received incomplete training from a passing mentor that died or left, or maybe they were outright expelled from their Order. Alternatively, at your DMs discretion this could be a later in life development if a player becomes disenchanted with their Monastic Tradition.

Pragmatism

At 3rd level, you embrace a more pragmatic view, gaining the following benefits:

• You have proficiency in improvised weapons. Improvised melee weapons count as Monk weapons for you.
• You gain proficiency in light armor and medium armor, and gain the benefits of Martial Arts and Unarmored Movement while wearing it.
• You can use your Strength modifier in place of your Wisdom modifier for calculating your ki save DC.

You gain the following additional Pragmatic Techniques you can spend ki on.

Kick ‘em While They’re Down (1 Ki). When you hit a target that is prone, restrained, or incapacitated, you can expend a Ki point to deal additional damage equal to two rolls of your Martial Arts die.

Unexpected Technique (1 Ki). When you make a grapple check, you can expend a ki point to add your Martial Arts die to the roll. You can do this after the contested roll, and it can potentially turn a failure into a success. On success, the target takes damage equal to the amount rolled on the added die.

Soak it Up

At 6th level, your extensive training in the art of getting hit with bar stools and broken bottles grants you increased endurance. When you roll initiative you gain temporary hit points equal to your Constitution modifier + your proficiency bonus. These temporary hit points are refreshed any time you take the Dodge action.

Where it Hurts

At 11th level, when you use Stunning Strike on a critical hit or on an attack made against an enemy that was unaware of you, the target has disadvantage on their saving throw against being stunned.

Lean Into It

At 17th level, you have thrown your fair share of walloping hits, and know how to make them reliably. You can forgo adding your proficiency bonus to an attack roll with an unarmed strike or melee monk weapon. When you do so, you can add twice your proficiency bonus to the damage roll.
