Monks following the Way of the Sensei are full of wisdom and insight which they impart to those around them. They are trained in combat similar to all monks, but are rarely the first to instigate in potential altercations.

Sage Advice

When you choose this order at 3rd level, you can guide other with your wise words. To do so, you use a bonus action on your turn to choose one creature other than yourself within 60 feet of you who can hear you. That creature gains one Sage Advice die, a d6. Once within the next 10 minutes, the creature can roll the die and add the number rolled to one ability check, attack roll, or saving throw it makes. The creature can wait until after it rolls the d20 before deciding to use the Sage Advice die, but must decide before the GM says whether the roll succeeds or fails. Once the Sage Advice die is rolled, it is lost. A creature can have only one Sage Advice die at a time. You can use this feature a number of times equal to your Wisdom modifier (a minimum of once). You regain any expended uses when you finish a long rest. Your Sage Advice die changes when you reach certain levels in this class. The die becomes a d8 at 6th level, a d10 at 11th level, and a d12 at 17th level.

Bounty of Advice

Beginning at 6th level, you regain all of your expended uses of Sage Advice when you finish a short or long rest.

Centered Defense

Starting at 11th level, you can calm your body and mind and prepare for a foe's attack. On your turn, if you move less than half you speed, you can use a bonus action to center yourself. Until the beginning of your next turn, if a hostile creature moves within 5 feet of you, you can use your reaction to make an unarmed strike against the creature with advantage. On a hit, the creature must succeed on a Dexterity saving throw against your ki save DC or be pushed up to 10 feet away from you and knocked prone.

Internalized Council

At 17th level, you have learned to recall advice you have given to others and apply it to your own life. As a bonus action on your turn, you can expend one of your Sage Advice dice and regain a number of ki points equal to the roll. Additionally, you can expend 7 ki points to regain a use of Sage Advice.
