Monks of the Way of the Sloth practice martial arts with efficiency, avoiding danger and attacking with no more effort than necessary. To this end, disciples of the Way of the Sloth will wait for the best time to strike and patiently conserve energy and reduce the amount of Ki expended to remain out of danger.

Patient Tactics

When you choose this tradition at 3rd level, you gain proficiency in the Perception skill if you don’t already have it. Your martial arts technique mixes combat training with the patience of a sloth. On your turn if your movement speed is greater than zero and you expend zero movement on that turn, you may use your patient defense without expending a Ki point.You may use this feature a number of times equal to your wisdom modifier between short rests.

Efficient Strike

At 3rd level, you learn to observe your opponents for openings as part of your Patient Tactics. Whenever you use Patient Tactics, on your following turn you may use your Flurry of Blows without expending a Ki point as long as no movement has been expended prior to your Attack that turn.

Restful Recovery

Beginning at 6th level, On your turn if your movement speed is greater than zero and you expend zero movement on that turn, as an action,  you can expend Ki points up to a number equal to your wisdom modifier to roll a die per Ki point spent to regain that number of  hit points.This die changes as you gain monk levels. At level 6 your Restful Recovery die is 1d4. At level 11 your Restful Recovery die is 1d6. At level 17 your Restful Recovery die is 1d8.

Nature's Cloak

By 11th level, you have learned to control your movements and be one with your surroundings. When you are in either forested or rocky terrain, you can use your action to become invisible. You remain invisible until you make an attack, cast a spell, move more than half your base speed on a turn, or are no longer on terrain with which you could cloak your movements.

Deft Perception

Starting at 17th level, your patience and perception of your surroundings result in more accurate execution of your plans. When you make an ability check, an attack roll, or a saving throw and have disadvantage on the roll, you can spend 2 ki points to cancel the disadvantage for that roll.

Tranquility

Beginning at 17th level, you can enter a special meditation that surrounds you with an aura of peace. At the end of a long rest, you gain the effect of a sanctuary spell that lasts until the start of your next long rest (the spell can end early as normal). The saving throw DC for the spell equals 8 + your Wisdom modifier + your proficiency bonus.
