What is flurry of blows 5e?

Flurry of Blows is a monk ability in the 5th edition of Dungeons and Dragons. It allows the monk to spend 1 ki point as a bonus action to make two unarmed strikes. These strikes must be made against a creature within 5 feet of the monk and are made at a disadvantage if the monk is also making a ranged attack during the same turn. At higher levels, the monk can make additional unarmed strikes as part of the ability. This ability can be used multiple times per turn as long as the monk has enough ki points to spend.
