In D&D 5e, a monk can use Martial Arts to attack twice. They can then spend a ki point to Dodge as a bonus action using the Patient Defense benefit of the Ki feature; if they have the Dwarven Fortitude feat (XGtE, p. 74), they can simultaneously heal themselves by spending a Hit Die.
Can this possibly be right? Can such a monk make 2 attacks and heal in the same turn?
Best Answer
You only have one bonus action on your turn
The additional attack from Martial Arts uses a bonus action (emphasis added):
Similarly, Patient Defense also uses a bonus action (emphasis added):
And you can only take one bonus action per turn:
Dwarven Fortitude does work with Patient Defense
The requirement for the relevant part of the Dwarven Fortitude feat reads (XGtE, p. 47):
And since Patient Defense does have you take the Dodge action (just as a bonus action), this meets the requirement listed in the feat. You should note that you are spending your Hit Dice to do this healing, eating into the healing resources for your short rest (and have taken a half feat for the privilege), and that you've spent a ki point (though the benefits of the Dodge action is often worth it). This totals one attack and some borrowed healing on one turn (until you get Extra Attack at 5th level, but that's built into the class).
