[RPG] How many times can a monk use Deflect Missiles in a round

Monks get the Deflect Missiles feature at 5th level.

How many times can a monk use Deflect Missiles in a round?

One of my players and I got into a debate. I contend that it is for one successful attack per round, while he maintains that it is more of a reaction and can be done as often as needed. Could someone please set us straight?

Best Answer

Deflect Missiles is a reaction:

Starting at 3rd level, you can use your reaction to deflect or catch the missile when you are hit by a ranged weapon attack.

You can only use one reaction per round.

From the PHB, page 190:

When you take a reaction, you can't take another one until the start of your next turn.

So he can do it once between each of his turns. Note that this also means he can't take any other reaction, such as an attack of opportunity.
