Say a level 3 monk is wielding a dagger in each hand, without the Two-Weapon Fighting fighting style or Dual Wielder feat. He makes a melee attack, then, as a bonus action, makes a ranged attack by throwing a dagger straight in the air above him. His turn ends before it falls, and if it hits him, he uses his reaction to catch and throw it.
Is this a valid use of Deflect Missiles according to RAW?
